    担当区分:最終著者

     概要を見る

    © Copyright © 2020 Nakano and Tanabe. In this work, thermal adaptation characteristics and thermal comfort zones were investigated in urban semi-outdoor environments in Tokyo. Four spaces with different levels of environmental control, i.e., heating, ventilation, and air conditioning (HVAC) spaces and non-HVAC spaces, were selected for the seasonal field surveys lasting over a period of 80 days. The survey consisted of the thermal environment measurement, questionnaire survey, and observation of occupancy conditions. The occupants were adapting themselves to fit within a certain range of standard effective temperature (SET∗). Clothing adjustment was the principal form of behavioral adaptation. The dominant factor affecting the clothing adjustment was the daily mean outdoor temperature, and not the immediate environment, in both the non-HVAC and the HVAC spaces. The total number of occupants and the mean occupancy period of the day had a strong linear relationship with the daily mean air temperature of the occupied zone in the non-HVAC spaces. No correlation was found between the thermal environment and the occupancy conditions in the HVAC spaces. Adaptive thermal comfort zones, not comfort temperatures, were derived directly from the subjective votes. The comfort zone in SET∗ was found to be 23–28°C for the predicted percentage of dissatisfied (PPD), 18–29°C for HVAC spaces, and 14–32°C for non-HVAC spaces. Occupants in semi-outdoor environments were tolerant to their thermal environment two to three times wider in range than the one predicted by the PPD. These findings are expected to be useful in the design and assessment of urban semi-outdoor environments.

  • Measurement of local evaporative resistance of a typical clothing ensemble using a sweating thermal manikin

    Akihisa Nomoto, Yoshito Takahashi, Shu Yoda, Masayuki Ogata, Shin‐ichi Tanabe, Shun Ito, Yuki Aono, Yoshihide Yamamoto, Kunio Mizutani

    Japan Architectural Review   3 ( 1 ) 113 - 120  2020年01月  [査読有り]

     概要を見る

    To accurately simulate human physiology and thermal comfort, certain human physiological and comfort models categorize the human body into multiple parts. Most of these body parts are normally clothed, which must be quantified in the simulation. However, existing databases of clothing evaporative resistance only characterize the evaporative resistance of the whole body and not those of individual body parts. This implies that each body part has the same level of clothing evaporative resistance. In this research, we measure the local clothing insulation and evaporative resistance. Here, we present the local thermal characteristic values as well as the values for the whole body.

  • Distribution of transient formaldehyde concentration in confined small glass desiccators and its impact on emission rate measurement

    Kang, Y., Yoo, S.-J., Takenouchi, K., Yoshida, H., Tanabe, S.-I., Ito, K.

    Atmospheric Environment   218  2019年12月  [査読有り]

     概要を見る

    © 2019 Elsevier Ltd The headspace method is used frequently for measuring the emissions rates of chemical compounds from building materials when operating labeling systems for these materials. A numerical investigation of transient formaldehyde concentration distribution in confined small glass desiccators was conducted in this study. To clarify the impact of the desiccator geometry on the formaldehyde emission and diffusion characteristics, three-dimensional (3D) laser-based measurement was first conducted to define the detailed inner geometries of the different commercial desiccators. A petri dish containing water was used as the sorbent for test specimens of formaldehyde emission sources produced inside the desiccators. Fundamental experiments concerning formaldehyde emission rates and sorption onto the sorbent were next performed using high- and low-emission types of building materials in the desiccators. Transient and steady numerical analyses were conducted for formaldehyde emissions from the building materials, molecular diffusion, and sorption onto the water sorbent. Transient analysis of the formaldehyde diffusion field over 24 h revealed that the total amount of dissolution of formaldehyde in the water was not significantly affected by the desiccator geometry in the building material of the inner diffusion control type. For evaporative/external diffusion emission-type, however, the formaldehyde emission rate was strongly affected by the desiccator shape. To obtain reproducible emission rate measurements in desiccators with different geometrical shapes, substantial adjustment is needed for the relative positions of the emission source and the sorbent in terms of the equivalent diffusion length, Ld.

  • Renovating a house to aim for net-zero energy, thermal comfort, energy self-consumption and behavioural adaptation: A method proposed for ENEMANE HOUSE 2017

    Oki, R., Tsuneoka, Y., Yamaguchi, S., Sugano, S., Watanabe, N., Akimoto, T., Hayashi, Y., Wakao, S., Tanabe, S.-I.

    Energy and Buildings   201   183 - 193  2019年10月  [査読有り]

     概要を見る

    © 2019 In Japan, low thermal insulation performance in existing houses is a considerable issue that may lead to health problems. Therefore, it is necessary to acquire technologies and knowledge regarding thermal insulation renovation. On the other hand, with the spread of photovoltaic panels, urban scale energy management and self-consumption have become important. The purpose of this study is to introduce a net-zero energy house which was designed, built, and analyzed by the team of Waseda University and Shibaura Institute of Technology in the ENEMANE HOUSE 2017 competition. The team proposed a renovation method which insert highly insulated walls into the existing structure, creating not only highly insulated areas but also non-insulated areas called “loggias.” By opening and closing the windows of the loggia according to the season, it functions as a passive system and enables residents’ behavioural adaptation to the environment. On the other hand, to aim for self-consumption and leveling of reverse power flow, a heat pump water heater and a storage battery were operated according to solar radiation prediction. Actual measurements confirmed the implementation and effect of this operational method. Moreover, the energy consumption was greatly reduced, while thermal comfort was maintained by thermal insulation and efficient equipment introduction.

  • A review of the surface heat transfer coefficients of radiant heating and cooling systems

    Shinoda, J., Kazanci, O.B., Tanabe, S.-I., Olesen, B.W.

    Building and Environment   159   106156 - 106156  2019年07月  [査読有り]

     概要を見る

    Heat transfer coefficients are often used to describe the thermal behavior of radiant systems in buildings and how they transfer heat between their cooled/heated surfaces and the room. In addition to current standards, several studies have been conducted to determine such heat transfer coefficients by means of experiments and simulations. Inconsistency is evident in the values and expressions derived for this purpose. The present study investigated possible sources of discrepancy in an extensive literature review of articles, standards and guidelines that focus on the heat transfer coefficients of cooled/heated surfaces. Measurement data provided by different authors were analyzed to compare both the amount of heat transfer and the estimated heat transfer coefficients. These estimated values and expressions were used to predict the measured data reported in other articles, to examine their accuracy. Larger deviations and prediction errors were found in the total and convective heat transfer values than in radiant heat transfer, which had a range of errors within +/- 20% throughout the literature. The major sources of error were shown to be the calculation procedure for each heat transfer mechanism, the choice of reference temperature and its measurement height and position, and room dimensions. It is suggested that heat transfer coefficients should be chosen by matching the calculation/measurement conditions in which they were obtained to the purpose and conditions in which they will be applied.

  • Applying TABS to a Publishing Company Headquarters Using Integrated Design

    Kosuke Sato, Eri Kataoka, Susumu Horikawa, Shin-ichi Tanabe, Jun Shinoda

    ASHRAE TRANSACTIONS 2019, VOL 125, PT 1   125   64 - 71  2019年01月  [査読有り]

     概要を見る

    This paper describes an example application of Thermo Active Building System (TABS) in a publishing company headquarters building located in the urban area of Tokyo, Japan. The successful integration of architectural, structural and building services design made it possible for this technology to be implemented. Since a part of the structure is utilized as a radiant surface instead of mounting ceiling panels, the floor height was greatly reduced. Some of the most important features of the novel TABS implemented in this building, are the alternately arranged nomal and reversed beams, which form a concave-convex salb structure. The bottom surface of the concave slab and beam structure works as a radiant surface for the lower floor, while the hollow space works as a passage for supply air for the upper floor. On the other hand, the hollow space in the convex structure works as a passage for return air and smoke exhaust from the lower floor.This means that all the space formed by slabs and beams are utilized for the building services. In addition, the building structure is effectively utilized as a radiant surface with a large heat storage capacity redacting electricuty demands during the peak period Furthermore, indoor temperature variation could be made smaller. In addition to the essential points of TABS, this paper reports the results of a mock-up experiment of the radiant cooling and heating system during the construction phase, and the results of the heat balance in a room. Moreover, it reports the results of a questionnaire distributed to occupants to investigate the indoor environment after the commencement of operation.

     概要を見る

    Recognizing the value of open-source research databases in advancing the art and science of HVAC, in 2014 the ASHRAE Global Thermal Comfort Database II project was launched under the leadership of University of California at Berkeley's Center for the Built Environment and The University of Sydney's Indoor Environmental Quality (IEQ) Laboratory. The exercise began with a systematic collection and harmonization of raw data from the last two decades of thermal comfort field studies around the world. The ASHRAE Global Thermal Comfort Database II (Comfort Database), now an online, open-source database, includes approximately 81,846 complete sets of objective indoor climatic observations with accompanying "right-here-right-now" subjective evaluations by the building occupants who were exposed to them. The database is intended to support diverse inquiries about thermal comfort in field settings. A simple web-based interface to the database enables filtering on multiple criteria, including building typology, occupancy type, subjects' demographic variables, subjective thermal comfort states, indoor thermal environmental criteria, calculated comfort indices, environmental control criteria and outdoor meteorological information. Furthermore, a web-based interactive thermal comfort visualization tool has been developed that allows end-users to quickly and interactively explore the data.

     概要を見る

    With growing attention to sustainability and recognition of the impact of global warming problems, energy supply and consumption have become critically important. This paper presents the construction of a modeling platform accommodating cooperative energy management systems (EMSs), which virtually produces the model of a smart city with a distribution network (DN) by using a wide range of data obtained from the real world. The platform involves models of various EMSs, governing the operation of a power system or controlling consumer-installed devices, and simulating the power flow, electrical losses, and voltage in the DN. In addition, indices measuring the sustainability of the model city, such as CO2 emission, are estimated from scenarios, for example, photovoltaic system installation, electric vehicle penetration, etc. The results can be visually displayed and the platform is highly versatile and applicable to various types of issues associated with smart cities. Two case studies are presented in detail.

  • Distributed Energy Management for Comprehensive Utilization of Residential Photovoltaic Outputs

    Yu Fujimoto, Hiroshi Kikusato, Shinya Yoshizawa, Shunsuke Kawano, Akira Yoshida, Shinji Wakao, Noboru Murata, Yoshiharu Amano, Shin-ichi Tanabe, Yasuhiro Hayashi

    IEEE TRANSACTIONS ON SMART GRID   9 ( 2 ) 1216 - 1227  2018年03月  [査読有り]

     概要を見る

    The introduction of photovoltaic power systems is being significantly promoted. This paper proposes the implementation of a distributed energy management framework linking demand-side management systems and supply-side management system under the given time-of-use pricing program for efficient utilization of photovoltaic power outputs; each system implements a consistent management flow composed of forecasting, operation planning, and control steps. In our framework, demand-side systems distributed in the electric distribution network manage individual energy consumption to reduce the residential operating cost by utilizing the residential photovoltaic power system and controllable energy appliances so as not to inconvenience residents. On the other hand, the supply-side system utilizes photovoltaic power maximally while maintaining the quality of electric power. The effectiveness of the proposed framework is evaluated on the basis of an actual Japanese distribution network simulation model from both the supply-side and demand-side viewpoints.

    Energy and Buildings   177   351 - 362  2018年  [査読有り]

     概要を見る

    Home energy management systems (HEMSs) are the system to manage the energy usage in houses. The use of HEMSs, and especially those which are capable of automatically controlling home energy appliances such as air-conditioners (ACs), is expected to manage energy utilized in domestic field effectively. In the present study, we focused on automatic AC operation by HEMS with the combined goal of improving thermal comfort while reducing electricity costs. In general, the room temperature and electricity consumption of an AC are highly dependent on the characteristics of the installation environment. so that the derivation of an appropriate AC operation plan is generally a difficult task. To tackle this problem, an energy management method to provide AC operation plan tailor-made for the target AC installation environmental by learning the characteristics of the installation environment (CIE) from the historical operation result data is proposed. The efficacy of the proposed method is verified via numerical and real-world experiments. (C) 2018 Elsevier B.V. All rights reserved.

     概要を見る

    &nbsp;Since a number of residential houses in Japan have built before 1980, they have very poor thermal insulation. With poor thermal insulation specification, the indoor thermal environment in winter could be so uncomfortable. The low temperature in houses could cause occupants' common cold, higher blood pressure, heat shock, and many other diseases.<br>&nbsp;Chapter 1 comprised previous studies, including ones about CASBEE Housing Health Checklist, and introduced the purpose of this research.<br>&nbsp;CASBEE Housing Health Checklist by Japan Sustainable Building Consortium (JSBC) is a type of software used to assess the health of residences. Answering 50 questions allows residents to identify the aspects of their home that affect their health. The score on the warmth is the sum of points for 7 questions about warmth in the checklist. The perfect score for each question is 3 points, therefore the perfect score for 7 questions is 21 points. Questions about warmth are intended to evaluate the thermal environment of both living rooms and non-living rooms. The first question is about the coldness of living room, the 2nd is about the coldness of bedroom, the 3rd is about the dryness of the bedroom, the 4th and the 5th are about the coldness of sanitary spaces, the 6th is about the coldness of toilet, and the last question is about the coldness of Corridor/Stairs/Closet. Examples of questions are as follows: &ldquo;Do you feel cold during heating the living room?&rdquo;, &ldquo;Do you feel cold in the toilet in winter?&rdquo;<br>&nbsp;The purpose of this research is proposing a method to calculate the score on the warmth, and making it possible to evaluate health performance of detached house by using room temperatures of simulation results. As using this method, it could be possible to indicate the necessity of thermal insulation of houses or help the occupants to consider an improvement of thermal insulation performance.<br>&nbsp;The calculation method to calculate the score on the warmth in a house is proposed in Chapter 2. Score on the warmth in CASBEE Housing Health Checklist is calculated from the temperatures that are simulated in the previous case study using a heat load simulation. The method to calculate the scores from temperatures is based on other studies about thermal sensation, health, dwelling performance and so on. For example, the score to the question of &ldquo;Do you feel cold in the toilet in winter?&rdquo; is calculated from operative temperature (OT), floor surface temperature of the toilet, and the OT difference between the bedroom and the toilet at late-night. Regarding converting OT into scores, 8&deg;C corresponds to 0 points, and 15&deg;C corresponds to full points. This allocation is decided based on the study that indicates the average toilet temperature that occupants felt cold was approximately 8&deg;C, and the average temperature that does not feel cold was approximately 15&deg;C.<br>&nbsp;Using the score on the warmth, it is possible to predict the crisis rate of catching a cold in winter. The predicted crisis rates are indicated in Chapter 3. The temperatures calculated in the case study simulation of houses with various thermal insulation levels are used to predict the crisis rates. For example, if a house with no insulation is replaced with a house which insulation performance meets the Japanese energy saving standard (so-called &ldquo;H25 Standard&rdquo;), the score raises approximately 6 points, and the rate of catching a cold in winter decreases approximately 15 %.

     概要を見る

    &nbsp;In the 23 wards of Tokyo, air-conditioners have been set up in all classrooms of public elementary and junior high schools since 2014. In Japan, the proportion of installing air conditioners in public classrooms of public elementary and junior high school is 49.6%, which is rapidly increasing. There is concern that energy consumption of elementary and junior high school will increase even further in the future. However, in Japan, the "Building Energy Efficiency Act" came into effect in 2016, and the thermal performance of the building's envelope and the method of calculating the primary energy consumption were determined. According to the specified method of calculation, two indices, Building Perimeter Index (BPI) and Building Energy Index (BEI) are obtained.<br>&nbsp;The purpose of this investigation is to comprehend the energy consumption situation of elementary schools in the Tokyo S ward, which is equipped with air conditioning facilities in all classrooms. First, we calculate the thermal performance of the envelope and the primary energy consumption according to the method prescribed in the "Building Energy Efficiency Act" and examine the correlation. Next, we compare the calculation result obtained by this calculation method with the actual measurement value. The following conclusions were obtained.<br>&nbsp;1) The average primary energy consumption of the primary school in S ward is 498 MJ /m2 per year. This significantly exceeded the primary energy consumption average of elementary and middle schools, 356 MJ /m2 per year nationwide and 305 MJ /m2 per year in the 6th climate zone including Tokyo.<br>&nbsp;2) The primary energy consumption of the elementary schools in S ward are classified into two categories based on the completion year. For these two model schools, the calculations were conducted based on the "Building Energy Efficiency Act". BPI and BEI for both school A of the new specification and school B of the conventional specification were less than 1.0, and satisfactory results were obtained. The BPI was lower in school A than that in school B, and the difference in thermal performance of the envelope appeared to be remarkable. The BEI of school B was lower than that of school A.<br>&nbsp;3) In addition, we calculated the energy consumption based on the type of building. The school building shows substantial air- conditioned energy consumption, and the gymnasium building shows significant lighting energy consumption. The consumption equipment ratio of the school building and the gymnasium were exceedingly different.<br>&nbsp;4) The energy consumption of the air-conditioning equipment accounts for 60% of the total consumption. The air conditioning energy consumption per floor area of school A exceeds that of school B. Converting to the calculation per air-conditioning floor area, the value for school A becomes lower than that of school B.<br>&nbsp;5) The design values of the primary energy consumption calculated from the "Building Energy Efficiency Act" were 454 MJ /m2 per year for school A and 341 MJ /m2 per year for school B. However the measured value of the primary energy consumption of the entire school was 585 MJ /m2 per year in case of school A and 449 MJ /m2 per year in case of school B. The design value was estimated to be approximately 3/4 of the measured value of the entire school, and the primary reason behind this difference is the use of kitchen equipment not being included in the calculation earlier

     概要を見る

    © 2017 The Authors. Indoor Air published by John Wiley & Sons Ltd Conditions in which exhaled and dermally emitted bioeffluents could be sampled separately or together (whole-body emission) were created. Five lightly dressed males exhaled the air through a mask to another, identical chamber or without a mask to the chamber in which they were sitting; the outdoor air supply rate was the same in both chambers. The carbon dioxide concentration in the chamber with exhaled air was 2000 ppm. Chamber temperatures were 23°C or 28°C, and ozone was present or absent in the supply airflow. When dermally emitted bioeffluents were present, the perceived air quality (PAQ) was less acceptable, and the odor intensity was higher than when only exhaled bioeffluents were present. The presence or absence of exhaled bioeffluents in the unoccupied chamber made no significant difference to sensory assessments. At 28°C and with ozone present, the odor intensity increased and the PAQ was less acceptable in the chambers with whole-body bioeffluents. The concentrations of nonanal, decanal, geranylacetone, and 6-MHO were higher when dermally emitted bioeffluents were present; they increased further when ozone was present. The concentration of squalene then decreased and increased again at 28°C. Dermally emitted bioeffluents seem to play a major role in the sensory nuisance experienced when occupied volumes are inadequately ventilated.

    JAPAN ARCHITECTURAL REVIEW   1 ( 1 ) 154 - 166  2018年01月  [査読有り]

     概要を見る

    The purpose of this paper is to clarify the causal relationship between certain factors through longitudinal research on health and living environment. Based on a questionnaire survey administered online to 5000 Japanese women in February 2011, and a follow-up survey of 3053 subjects undertaken in February 2013, an analysis was performed on 1575 people with a history of low back pain. First, causal relationships between 2 factors, "Chronic low back pain" and "Stress and fatigue," were analyzed using cross-lagged effects modeling and synchronous effects modeling. Similarly, causal relationships between 2 factors, "Stress and fatigue" and "Satisfaction with living environment," were analyzed using the 2 models. It was revealed that "Satisfaction with living environment" affects "Stress and fatigue," and "Stress and fatigue" affects "Chronic low back pain." Covariance structure modeling was used to show that "Satisfaction with living environment" indirectly affects "Chronic low back pain" through "Stress and fatigue" using longitudinal data. Accordingly, it was shown that improving the satisfaction with living environment can improve health in terms of stress, fatigue, and chronic low back pain. Moreover, it was suggested that CASBEE Health Checklist 6 score (group with good housing environment) and health variables were related.

     概要を見る

    &nbsp;Currently, most detached houses in Japan are airtight wooden structures that have a high risk of vapor condensation in the wall cavities. Vapor condensation in insulation material is a primary contributor to mold growth in wall cavities. Indoor mold concentrations depend not only on indoor mold sources, but also on infiltration from concealed spaces, such as beam space and crawl space. The air pollutants infiltrate houses from these spaces by indoor decompression via the ventilation system, and mold that infiltrates through the glass wool used for heat insulation may remain and grow on the material. In order to measure the mold concentrations in glass wool, a new method is required for air cavity sampling. A method using a Teflon tube inserted into thin spaces in wall cavities or crawl spaces is useful for accomplishing this task. The surface of Teflon is very smooth, but mold adheres to it because of friction or static electricity. The objectives of the present investigation were to develop a method to measure mold concentration using Teflon tubes and to characterize the movement of mold spores between heat insulators.<br>&nbsp;The following conclusions were obtained from this study:<br>&nbsp;(1) The mean rates of mold retention in 0.3, 0.5, and 1.0 m Teflon tubes, which were washed three times with sterilized physiological salt solution, were 5%, 21%, and 37%, respectively. This indicated that retention rates increase with increases in Teflon tube length, and it was concluded that a useful sampling method for concealed spaces must use a Teflon tube that is about 0.3 m long, given the retention rate. Data from inter-laboratory testing indicated that a Teflon tube that is 1 m long is unsuitable for this sampling method.<br>&nbsp;(2) The amount of mold spores in the glass wool heat insulator decreased the more it was washed using sterilized physiological salt solution to clarify the movement of mold spores. After the third wash, the desorption rate of mold spores in the glass wool was about 85%, showing that three rounds of washing were required to measure the mold movement.<br>&nbsp;(3) Measurement of the movement of mold spores inside the heat insulator showed that the quantity of mold spores adhering to the heat insulator decreases exponentially with an increase in length of the Teflon tubes.<br>&nbsp;(4) In this range of the wind velocity, the movement of mold spores between insulators through the heat insulator is not significantly influenced by wind in the small chamber.<br>&nbsp;(5) The experimental results indicate that the quantity of mold spores displaced from the heat insulator by air transportation was not significant.

    Indoor air quality of homes, workplaces, public buildings, and cabins of transportation vehicles plays an essential role in the health and well-being of individuals. During recent decades, interest in indoor air research increased significantly as is reflected in the increasing number of scientific publications and international standards. Various ambient (outdoor) air quality standards and regulations have been established within many countries to protect public health. However, indoor air quality standards with legally binding force are scarce. Currently, consumer demand is helping to drive manufacturers using product labels indicating so-called "low emissions" as a marketing tool.

  • Concentration of Formaldehyde, Acetaldehyde, and Five Volatile Organic Compounds in Indoor Air: The Clean-Healthy House Construction Standard (South Korea)

    JOURNAL OF ASIAN ARCHITECTURE AND BUILDING ENGINEERING   16 ( 3 ) 633 - 639  2017年09月  [査読有り]

     概要を見る

    The authors evaluate indoor air quality in apartments built according to the South Korean Clean-Healthy House construction standard. The evaluation includes three types of residential units with differing gross floor areas. Indoor air was analyzed for formaldehyde (observed range 52.0-99.2 ug/m(3)), acetaldehyde (14.6-61.0 ug/m(3)), benzene (0.6-1.3 ug/m(3)), toluene (161.8-371.0 ug/m(3)) ethylbenzene (6.5-17.0 ug/m(3)), xylene (14.7-45.0 ug/m(3)), and styrene (37.7-112.5 ug/m(3)). The concentrations of all analyzed substances were within the South Korean guidelines. The findings confirm that the Clean-Healthy Homes initiative has led to a greatly improved indoor air environment compared to existing newly built apartment blocks in South Korea. However, this construction standard is applied only to large apartment developments comprising 1,000 or more units, and it seems that further effort should be made to extend the standard to stand-alone residences and small-scale apartment blocks in order to ensure that indoor air quality is maintained more widely.

  • Measuring Degree of Contamination by Semi-volatile Organic Compounds (SVOC) in Interiors of Korean Homes and Kindergartens

    Hyun-tae Kim, Shin-ichi Tanabe

    JOURNAL OF ASIAN ARCHITECTURE AND BUILDING ENGINEERING   16 ( 3 ) 661 - 668  2017年09月  [査読有り]

     概要を見る

    PVC floor material is widely used in Korean homes, and people customarily sit or lie on the floor surface. This could potentially put residents of such homes at high risk of exposure to semi-volatile organic compounds (SVOCs). However, there is a current lack of information regarding the degree of SVOC contamination in Korean homes. Therefore, this study was implemented to measure SVOC concentration in the air and house dust in homes and kindergartens, places where children spend long periods of time. The substances analyzed were 2E1H, D6, DEP, TBP, TCEP, DBP, TPP, DOA, and DEHP. Amounts of 2E1H, D6, DEP, DBP, and DEHP were detected in the air of the homes included in the study, and the average air concentrations of DBP and DEHP were 0.53 mu g/m(3) and 0.28 mu g/m(3), respectively. The average dust DEHP concentrations in the rooms of homes and kindergartens were 2,800 mu g/g and 4,350 mu g/g, respectively, showing that higher values were measured in kindergartens. The measured DEHP concentrations in the dust of both homes and kindergartens where PVC floor materials are used were high.

     概要を見る

    &nbsp;The purpose of this research is to evaluate the economic value of certification of green buildings based on j-reit (Japan Real Estate Investment Trust) owned office buildings. In the recent years, assessment systems for the environmental performance of buildings are being widely used in Japan. Some analyses were conducted in Japan to investigate whether green building certificates have a positive influence on the contract rent. However we need to investigate profits and expenses of the real estate rent to clearly explain the economic benefits of green buildings.<br>&nbsp;In this research, we analyze the office building annual data in Japan which was disclosed by J-REIT. Operating benefits and utilities costs of 657 buildings in January 2014 - December 2014 was analyzed. Regarding the objective office, the total leased area is under 50000 m2 and each building was divided into green building certified or Non-certified. Subject green building certifications are Tokyo Top-Level Business Facility and CASBEE (Comprehensive Assessment System for Built Environment Efficiency).<br>&nbsp;The net operating incomes of Top-Level Business Facility or CASBEE certified office buildings over 10000 m2 of total building area are bigger than that of not certified office buildings. The utilities costs of Top-Level Business Facility certified office buildings are the same as that of not certified office buildings, but the utilities cost of CASBEE certified office buildings is bigger than that of not certified office buildings. The net operating incomes of CASBEE certified office buildings over 3000 m2 and less than 10000 m2 of total building area are bigger than that of not certified office buildings. The utilities costs of CASBEE certified office buildings over 3000 m2 and less than 10000 m2 are the same as that of not certified office buildings. The net operating incomes of expired CASBEE certified office buildings over 10000 m2 of total building area are bigger than that of not certified office buildings. The utilities costs of expired CASBEE certified office buildings are the same as that of not certified office buildings. Using these results, the environmental performance of Top-Level Business Facility certified office buildings over 10000 m2 of total building area and expired CASBEE certified office buildings over 10000 m2 of the area, CASBEE certified office buildings over 3000 m2 and less than 10000 m2 of the area may be high in the value of the real estate.<br>&nbsp;The utilities costs of buildings are not always related to the energy consumption, because an energy source, a type of contract and a contract fee are different in each building. In this survey, the primary energy consumption of CASBEE real estate buildings is correlated with the utilities cost of the buildings. The objective buildings do not install the regional air-conditioning.

  • Emerging developments in the standardized chemical characterization of indoor air quality

    Sascha Nehr, Elisabeth Hoesen, Shin-ichi Tanabe

    ENVIRONMENT INTERNATIONAL   98   233 - 237  2017年01月  [査読有り]

     概要を見る

    Despite the fact that the special characteristics of indoor air pollution make closed environments quite different from outdoor environments, the conceptual ideas for assessing air quality indoors and outdoors are similar. Therefore, the elaboration of International Standards for air quality characterization in view of controlling indoor air quality should resort to this common basis. In this short review we describe the possibilities of standardization of tools dedicated to indoor air quality characterization with a focus on the tools permitting to study the indoor air chemistry. The link between indoor exposure and health as well as the critical processes driving the indoor air quality are introduced. Available International Standards for the assessment of indoor air quality are depicted. The standards comprise requirements for the sampling on site, the analytical procedures, and the determination of material emissions. To date, these standardized procedures assure that indoor air, settled dust and material samples are analyzed in a comparable manner. However, existing International Standards exclusively specify conventional, event-driven target-screening using discontinuous measurement methods for long-lived pollutants. Therefore, this review draws a parallel between physico-chemical processes in indoor and outdoor environments. The achievements in atmospheric sciences also improve our understanding of indoor environments. The community of atmospheric scientists can be both ideal and supporter for researchers in the area of indoor air quality characterization.This short review concludes with propositions for future standardization activities for the chemical characterization of indoor air quality. Future standardization efforts should focus on: (i) the elaboration of standardized measurement methods and measurement strategies for online monitoring of long-lived and short-lived pollutants, (ii) the assessment of the potential and the limitations of non-target screening, (iii) the paradigm shift from event-driven investigations to systematic approaches to characterize indoor environments, and (iv) the development of tools for policy implementation.

     概要を見る

    This study examines the relationship between individual thermal satisfaction and worker performance. Field measurements and a questionnaire survey were conducted within an organization participating in the COOL BIZ energy conservation campaign. A subjective experiment was also conducted in a climate chamber with eleven Japanese male subjects, testing five scenarios combining operative temperature (25.5 degrees C and 28.5 degrees C), clothing (with and without suits), and cooling items (desk fan, air-conditioned shirt, mesh office chair). From the individual analysis, actual air temperature in the COOL BIZ office was poorly correlated with self-estimated performance, whereas perceived thermal satisfaction correlated well with self-estimated performance (R-2 = 0.944, p < 0.001). The results of the subjective experiment indicate that performance during simulated office work (i.e. multiplication and proof reading tasks) increased with greater individual thermal satisfaction (R-2 = 0.403 and 0.464, p < 0.001). The finding that perceived thermal satisfaction of occupants is reflected in objective measurement of office work performance has practical implications for the evaluation of thermal satisfaction in real offices as a means to boost workplace productivity.

  • Workers' awareness and indoor environmental quality in electricity-saving offices

    Sayana Tsushima, Shin-ichi Tanabe, Kei Utsumi

    BUILDING AND ENVIRONMENT   88   10 - 19  2015年06月  [査読有り]

     概要を見る

    Owing to the enormous damage caused by the Great East Japan Earthquake of 2011, a 15% reduction in peak power consumption was required to address the gap between demand and supply capabilities in the summer of 2011. Electricity-saving measures are promoted in offices today for both environmental and safety reasons, and indoor office environments have changed greatly. This paper aims to reveal to what extent workers' awareness of electricity-saving has changed since the earthquake disaster had an impact on energy consumption and productivity. The authors have conducted continuous fieldwork and questionnaire surveys in seven electricity-saving office buildings in the summers of 2011-2013. Additionally, our laboratory's past research data were collected together and analyzed. The results show that excessive indoor air temperatures, such as 28 degrees C, were avoided, and the desk level illuminance greatly decreased, from 750 lux to around 400 lux, after the earthquake. People learned to implement electricity saving in a proper way that does not spoil workers' comfort, and workers' acceptability zone for the indoor environment was extended by the experience of electricity-Saving. Moreover, when we compared individual differences in the way environmental information is perceived, it was shown that differences in the workers' awareness of electricity-saving had a more profound effect on their satisfaction with the indoor environmental quality than those in their gender or age. Mechanical power-saving is definitely important; however, building devices that induce the occupants' energy-saving actions are vital. Our results will be considerably useful to other countries, whether or not they experience a natural disaster. (C) 2014 Elsevier Ltd. All rights reserved.

     概要を見る

    In Japan, many people feel cold in housing during winter. In this study, focusing on comfortable thermal environment for people sensitive to cold in housing during winter, subjective measurements were carried out experimentally. People sensitive to cold and not so selected as subjects were exposed to climate chamber controlled to 5℃, heating room controlled to 21℃, and non-heating room controlled to 14℃, 16℃, 18℃. The results of this study are as follows: (1) the whole body and hand/foot thermal sensation correlates well with the thermal comfort in both groups of subjects; (2) in case of examining skin temperature of extremities during winter, that of fingers should be measured instead of back of hand and instep, and (3) people sensitive to cold felt cold, especially in their foot during experiment all the time. When examining the comfort of residents in housing, it is very important to considering difference of their constitution.

    The purpose of this paper is to clarify the causal relationship for from longitudinal research with health and living environment. Based on a questionnaire longitudinal survey administered online to Japanese women of 3054 in 2011 and 2013, about 1500 people with a history of low back pain, covariance structure analysis was conducted to explore the relationship between satisfaction of living environment, stress-related health and chronic low back pain. The models showed that there was a causal effect from &quot;stress and fatigue&quot; to &quot;chronic back pain&quot;, while a second causal effect was shown from &quot;satisfaction of living environment&quot; to &quot;stress and fatigue.&quot; Taken together, this suggests that &quot;satisfaction of living environment&quot; influences levels of &quot;stress and fatigue&quot; which in turn manifests itself as &quot;chronic low back pain.&quot;

    Recently, residences are becoming more insulated and airtight for energy saving action. In such residences, floor heating (radiative system) and air conditioner (convective system) have become widely used. So the thermal comfort in rooms heated by floor heating or air conditioner was compared by the thermal manikin. The experiment for the thermal manikin was performed in the artificial climate chamber. When sensible heat loss became thermal neutrality, the thermal comfort in rooms heated by floor heating or air conditioner was compared by air temperature. In the result, for all conditions air temperature by floor heating was lower than that by air conditioner.

  • Influence of sorption area ratio and test method on formaldehyde reduction performance for sorptive building materials

    Hoon Kim, Shin-ichi Tanabe

    CONSTRUCTION AND BUILDING MATERIALS   70   175 - 182  2014年11月  [査読有り]

     概要を見る

    Sorptive materials can be used to improve the air quality by adsorbing harmful chemicals and other pollutants in indoor air. This study aims to (1) investigate the differences in the reduction performance values with changes in surface area ratios of sorptive materials for the two test methods (constant concentration supplying method and emission material method, hereinafter CCSM and EMM); (2) discuss whether the sorption flux "F-s" and equivalent ventilation rate "Q(eq)", which are two ways of representing the results, can accurately represent the reduction performance; and (3) suggest a method for compensating for disparities between the two test methods.Under the standard sorption area condition, CCSM yielded F-s with higher performance than EMM. The evaluation using F-s gave more advantage to a smaller sorption area condition, and CCSM was less influenced by the area than EMM. Changes in the area ratios resulted in changes in F-s, but Q(eq) was less affected. However, for an identical area ratio condition, F-s resulted in steady values, while Q(eq), fluctuated owing to subtle changes in chamber concentrations. Compensation using the HBF (Hoetjer-Berge-Fujii) equation could improve EMM performance value and thus reduce the disparity between the two methods. (C) 2014 Elsevier Ltd. All rights reserved.

     概要を見る

    The Great East Japan Earthquake and Tsunami which occurred on March 11, 2011 caused widespread damage and electricity shortage. So the Japanese government has directed large-scale electricity users to curb their consumption by 15 percent of what they used last summer. However, excessive saving electricity forces office workers to be patient, and it can lead to productivity decline. In this study, the field survey and questionnaire survey were conducted in six buildings saving on electricity to study the indoor environment, the workers productivity and energy conservation. As a result, it was found that the rise of temperature leads to the sharp decline of productivity and comfort, and that power saving of lighting made less dissatisfaction for office workers and reduced more electric energy than turning up the air conditioning. Office workers can keep productivity if there are no dissatisfactions for them. Therefore, lowering illuminance is found to be more effective for saving electricity than turning up the air conditioning.

    INDOOR AND BUILT ENVIRONMENT   23 ( 5 ) 653 - 664  2014年08月  [査読有り]

     概要を見る

    Information on the compositions of construction products is useful to construction designers, builders and occupants to help establish good indoor air quality and building environment. Existing measures to deliver this information, such as labelling or material safety data sheets, have not been adequate for construction products. The study aims to evaluate the status of the current information-delivery system and clarify requirements for a future system. A questionnaire survey on the current status and requirements of an information-delivery system for construction-product compositions was conducted in Japan. In total, 203 manufacturers, including two associations, and 35 users responded. Responses relating to 439 and 226 products from manufacturers and users, respectively, were obtained. Majority of the manufacturers and users responded that a standardized scheme is needed. Large discrepancies were noted between the delivery levels required by users and the actual levels from manufacturers in terms of the information-delivery range and display elements. The limitations of information delivery for manufacturers differed between composite products or equipment and products in which the compositions played an important role in quality and performance. Concerns included the cost and manpower required to examine the compositions for new information-delivery system and the importance of maintaining consistency with existing systems.

     概要を見る

    Semi-outdoor environment is defined as a grade of environmental control in thermal environmental planning, falling in between indoor and outdoor environment. Thermal adaptation of occupants, together with building and equipment, needs to be taken into account for planning such environment. Behavioral and psychological adaptation was found to be influential on thermal comfort, and context of thermal environment was found to be important to understand the adaptive process from literature review. Environmental context was categorized into social, architectural, and personal elements. A concept model of adaptive thermal comfort in semi-outdoor environment was proposed. Problems concerning application of existing thermal comfort standards were discussed. Adaptive comfort zone, not comfort temperature, needs to be investigated through field surveys considering the Japanese context such as geographical location, climate, degree of environmental control and general-purpose of the architectural space. Adaptive comfort zone needs to be presented together with the definition of environmental context.

    Semi-volatile organic compounds (SVOCs) have low volatility and tend to adhere to dust particles. Recently, many scientific papers show that SVOCs may have a health risk, especially affect for children. Wensing showed that infants take dust 10 times more than adults. Considering the health damages and the intake of dust, the risk of infants exposing to SVOCs might be high. Therefore, it is necessary to assess SVOCs pollution situation of the residences and children welfare facilities which are the main life space for infants. Although many results of measurements for the SVOCs concentrations of dust at residences have been reported in Japan and overseas, few of them are at children welfare facilities. In this paper, we measured SVOCs concentrations of dust at four child welfare facilities, to assess the degree of SVOCs pollution in those places.As a result, in many cases the SVOCs concentrations of dust at children welfare facilities were high compared with that of residences. Also, higher SVOCs concentrations were observed in rooms with polyvinyl chloride (PVC) flooring materials compared with that in rooms with wood-based flooring material.

     概要を見る

    Some field surveys were conducted in the offices in Tokyo to investigate worker&#039;s comfort and productivity under the saving electricity after the Great East Japan Earthquake. However, we need nationwide survey because saving electricity is ongoing all over Japan now. In this study, we conducted web-based questionnaire in Tokyo, Nagoya and Osaka to know the workers&#039; awareness and measures of saving electricity. As a result, similar saving electricity measures were implemented in three areas and lowering illuminance made less dissatisfaction than turning up the set point of the air conditioning. It is estimated that workers&#039; awareness of saving electricity was different because of the areal targeted value of saving electricity. Workers&#039; satisfaction of the office environment was affected to a large degree by not only indoor environment or their gender and age, but also their feelings.

    BUILDING AND ENVIRONMENT   71   153 - 164  2014年01月  [査読有り]

     概要を見る

    The effects of indoor air quality on symptoms, perceptions, task performance, cerebral blood flow, fatigue, and mental effort of individuals working in an office were investigated. Twenty-four right-handed Danish female subjects in an office were exposed in groups of two at a time to two air pollution levels created by placing or removing a pollution source (i.e. a used carpet) behind a screen. During the exposure, the subjects performed four different office tasks presented on a computer monitor. The tasks were performed at two paces: normal and maximum. When the pollution source was present, the air quality was perceived to be worse and more errors were made when subjects typed text at the maximum pace. No other changes in subjective responses, performance, or physiological measurements were associated with different exposures. Although cerebral blood flow and voice analysis did not detect any effects caused by modifying pollution exposure, they were well correlated with increased mental effort when the tasks were performed at maximum pace and subjectively reported fatigue, which increased during the course of exposure, respectively.

     概要を見る

    Climate change and the urgency of decarbonizing the built environment are driving technological innovation in the way we deliver thermal comfort to occupants. These changes, in turn, seem to be setting the directions for contemporary thermal comfort research. This article presents a literature review of major changes, developments, and trends in the field of thermal comfort research over the last 20years. One of the main paradigm shift was the fundamental conceptual reorientation that has taken place in thermal comfort thinking over the last 20years; a shift away from the physically based determinism of Fanger's comfort model toward the mainstream and acceptance of the adaptive comfort model. Another noticeable shift has been from the undesirable toward the desirable qualities of air movement. Additionally, sophisticated models covering the physics and physiology of the human body were developed, driven by the continuous challenge to model thermal comfort at the same anatomical resolution and to combine these localized signals into a coherent, global thermal perception. Finally, the demand for ever increasing building energy efficiency is pushing technological innovation in the way we deliver comfortable indoor environments. These trends, in turn, continue setting the directions for contemporary thermal comfort research for the next decades.

    The Great East Japan Earthquake on March 11, 2011 caused widespread damage, especially electricity shortage. Therefore the Japanese government has directed large-scale electricity users to curb their consumption by 15 percent of what they used in the previous summer. Most companies in Tokyo were saving electricity by reducing their use of lights and air conditioning systems in their offices. decline. Few field investigations have been conducted under special conditions including after big disasters. Purpose of this study is to find efficient strategies for saving electricity that do not decrease workers&#039; productivity so much. In this report, energy consumption of existing building have analyzed and prepared between before the great east Japan earthquake and after. Further, it experimented on the conditions which changed an illumination setup and an air-conditioning setup under power-saving environment, and conducted the sensitivity analysis of each item in analyzing the power consumption on each condition.

    BUILDING AND ENVIRONMENT   66   1 - 10  2013年08月  [査読有り]

     概要を見る

    A human thermoregulation model called JOS-2 was developed based on the Stolwijk model and our previously developed (in 2002) JOS model. In this model, the whole body was idealized as 17 spherical or cylindrical body segments (Head, Neck, Chest, Pelvis, right and left Shoulders, right and left Arms, right and left Hands, right and left Thighs, right and left Legs, and right and left Feet). The Head segment consists of four layers-core, first layer, second layer, and skin-and the other segments consist of two layers-core and skin). All body segments have artery and vein blood pools. In addition, the limb segments have a detailed vascular system consisting of superficial veins and arteriovenous anastomoses (AVA). Thermoregulatory mechanisms such as vasoconstriction, vasodilation, perspiration, and shivering are considered. The physical parameters of this model, such as height, weight, sex, age, body fat percentage, basal metabolic rate, and cardiac index, can be changed. This paper describes the equations and coefficients as well as the model validation for stable, nonuniform, transient conditions. (C) 2013 Elsevier Ltd. All rights reserved.

    ARCHITECTURAL SCIENCE REVIEW   56 ( 1 ) 4 - 13  2013年02月  [査読有り]

     概要を見る

    Little is known of workers' comfort and productivity under special conditions, particularly after large disasters. The Great East Japan Earthquake in 2011 caused enormous damage, leading to a 15% peak-power reduction to address power shortages. We investigated occupants' comfort and productivity in five office buildings in Tokyo during the summer season under mandatory electricity savings implemented after the earthquake. We changed the temperature, illumination and ventilation rate settings to investigate their effects on thermal comfort, productivity and energy levels. Occupants were more receptive towards decreased illumination than increased temperature. Awareness of power savings was increased, with more than 90% of people accepting the poor indoor environment in the light of recent events. Set-point temperature and clothing recommendations made by the Super Cool Biz campaign were followed in most offices. However, self-estimated productivity was 6.6% lower than the previous summer. Thus, electricity-saving strategies that do not affect productivity are required.

     概要を見る

    Air-cleaning systems using a low concentration of chlorine dioxide (ClO2) gas for prevention against infection by the influenza virus have been developed. ClO2 gas is easily decomposed by indoor climate factors. Three experiments were conducted to evaluate the effects of indoor environmental factors on the decrease of ClO2 gas concentration. The reaction (decay) rate constant was also determined. High air temperatures and light irradiation accelerated the decrease of ClO2 gas concentration; the latter had the greatest influence on the decrease of ClO2 gas concentration among the conditions. A quicker decay of concentration and greater value of the reaction rate constant of ClO2 was found when a UV lamp was used; this is because the gas absorbs irradiation in the UV range. ClO2 gas concentration was significantly reduced when an evaporative humidifier was employed due to adsorption and a chemical reaction between the gas and the filter in the humidifier.

    Phthalates are used as plasticizers and flame retardants in building materials and phthalates emitted in indoor environment tend to adhere to house dust. According to Wensing, infants take dust 10times as adults, so an investigation on the concentration of phthalates in house dust is important. This study examined the concentration of phthalate in house dust in Japan and Korea. Specially, Korea house much used polyvinyl flooring as floor product and also used floor heating system during the winter. As a result, the amount of the collected dust per square meter in Japan house was more than the one in Korea house. In addition, the amount of house dust in Japan was more than the one in Korea house, even in under dust 63μm. And the concentration of DEHP in the houses investigated in Korea was higher than 50 percentile in Germany and some Korea houses were higher than 95 percentile in Germany. Japan houses investigated had lower concentration of DEHP in house dust than 95 percentile in Germany, and some house in Japan were lower than 50 percentile in Germany.

    For the improvement of the air quality of indoors, it is necessary to determine the kinds and the concentration of the chemical substances that emit from building products and production parts. On this study, the heating temperature, the amount of the nitrogen filling, and the heating time, etc. was executed as an important item related to the measurement of bag method. It was a tendency that the recovery percentage raises with the rise of the heating temperature as a result of examining the recovery percentage by using the standard test solution, too. Therefore, 65 degrees of the heating temperature is preferable. However, the recovery percentage is less than 80% at even 65 degrees in heating temperature, and it has been understood that it is unsuitable in the measurement in the bag method in Tetradecan. In addition, it has been understood that the bag value calculated from the chamber method becomes small more than the bag value calculated from the bag method.

     概要を見る

    The environment of workplace in an office involved in creative work was evaluated in 2005 and 2006. The M Company has installed partition based task/ambient conditioning systems (TAC) and several environment-friendly systems, such as double-skin and thermal-storage structures. It was intended to investigate the influence of the worker's behavior and task conditioning on worker's thermal comfort and productivity. In this survey, immediate thermal environment and worker's behavior were measured, and occupants' surveys of thermal comfort and feeling of fatigue were conducted. We found that both activity level of occupant and exposed thermal environment is greatly different one by one. It is suggested that an increase in metabolic rate according to worker's behavior influenced on their thermal comfort. Based on the knowledge obtained from this investigation, needs for TAC are discussed. (C) 2009 Elsevier Ltd. All rights reserved.

     概要を見る

    Conventional multi-zonal ventilation measurement methods by multiple types of perfluorocarbon tracers use a number of different gases equal to the number of zones (n). The possible n x n+n airflows are estimated from the mass balance of the gases and the airflow balance. However, some airflows may not occur because of inter-zonal geometry, and the introduction of unnecessary, unknown parameters can impair the accuracy of the estimation. Also, various error factors often yield an irrational negative airflow rate. Conventional methods are insufficient for the evaluation of error. This study describes a way of using the least-squares technique to improve the precision of estimation and to evaluate reliability. From the equations' residual, the error variance-covariance matrix Lambda(q) of the estimated airflow rate error is deduced. In addition, the coefficient of determinant using the residual sum of squares and total variation is introduced. Furthermore, the error matrix (m)Lambda(q) from the measurement errors in the gas concentration and gas emission rate is deduced. The discrepancy ratio of the model premises is defined by dividing the diagonal elements of the former by those of the latter. Moreover, the index of irrationality of the estimated negative airflow rate is defined, based on the different results of the three estimation methods. Some numerical experiments are also carried out to verify the flow rate estimation and the reliability evaluation theory. (C) 2008 Elsevier Ltd. All rights reserved.

     概要を見る

    近年の空気質への関心の高まりを受けて、日本自動車工業会は車室内のVOCs低減に関する自主規制を公表した。しかし、実測データの公表事例が少ない。そこで、本研究では車室内の実測から放散しているVOCs成分と濃度の把握を行なった。この結果より、トルエン、キシレンなどの成分の低減が行なわれている車両であってもTVOC濃度は低減されていない場合があることが分かった。また、発生ガス濃縮装置を用いて部品から放散する成分を測定した結果、SVOCs成分も多く放散しており、VOCs同様に低減対策が必要であることが分かった。更に、トルエンの放散濃度が一番高かった部品のトルエンの低減対策により、車室内のトルエン濃度を下げることができた。

    温冷感を一定に保ったSET^*一定環境で、定常状態および代謝量が上昇した非定常状態において、湿度が在室者の熱的快適性に及ぼす影響を検討することを目的とした被験者実験を行った。実験条件は、温冷感を一定に保つため等SET^*とし、SET^*26℃、28℃の2条件を設定した(代謝量1.2met時)。各SET^*条件に対し、相対湿度4条件(35%RH、55%RH、65%RH、75%RH)を設定し、空気温度を調節した。本実験で設定したような熱的中立に近い等SET^*条件では、定常状態において、環境の湿度が被験者の温熱感覚(温冷感、熱的快不快感、熱的受容度)、湿度感覚(乾湿感、湿度受容度)に及ぼす影響は小さかった。本実験ではSET^*を一定に保つために、湿度を低下させた場合、空気温度を上昇させている。このため、等SET^*条件下では湿度が変化しても被験者の熱的快適性が等価に保たれていると考えられる。代謝量が上昇した場合、高湿度環境では、代謝量が上昇した際の温冷感、熱的不快感が高くなり、乾燥感が低下した。SET^*一定条件では、湿度の上昇に伴い皮膚水分量は高くなった。

    Subjective experiments were conducted to evaluate the effects of humidity on human comfort and productivity under transient conditions from hot and humid environment to thermally neutral condition. Two climate chambers, "Chamber 1" and "Chamber 2", adjoined each other were used for this study. Subjects were exposed to 30 degrees C/70%RH air in Chamber 1 for 15 min with 2.0 met of metabolic rate. Then they moved into Chamber 2, where 4 humidity conditions, 30, 40, 50 and 70%RH were examined. Air temperature was adjusted to keep SET* constant at 25.2 degrees C for all conditions. Subjects were exposed in Chamber 2 for 180 min performing 2 kinds of simulated office work.Positive effects of low humidity on subjective pleasantness were found under transient condition at low humidity due to more evaporation from human body, while no significant difference in thermal sensation and humidity sensation among 4 relative humidity levels was obtained. Subjective performance was found to be at the same level under all conditions. However, subjects reported to be more tired at 70%RH after humidity step change. (C) 2006 Elsevier Ltd.

    Subjective experiments with task conditioning systems, 3DU(+), PEM, TU, and RCU were conducted to investigate the effect of three different types of Task air-conditioning systems on thermal comfort in a climate chamber. The chamber was conditioned at 28 degrees C/50%RH with task systems and 26 degrees C/50%RH without them. Under the condition with the task conditioning systems, the average rating of comfort sensation was between comfortable (0) and slightly uncomfortable (-1). For males it was between -0.5 and -0.7 and for females between -0.3 and -0.4. This was equal to or even better than that in condition without task system. It was found that these systems were effective in providing thermal comfort. The parts to which subjects wanted to diffuse air were different for each system. However, the individual control of task conditioning system contributed to create the preferred environment. (C) 2006 Elsevier Ltd. All rights reserved.

    In recent years, natural ventilation system is widely used for sustainable buildings. However, systems without proper managements and maintenances are often observed. Noise and pollution are major problems in the urban environment. Wide investigation was conducted for 72 buildings. The reason of less use of natural ventilation system was investigated by the field measurements and questionnaire to the designers, building managers and occupants. The reasons are classified into three categories, 1) complains of occupants, 2) control system of natural ventilation, 3) clear understanding of the natural ventilation system by building managers and occupants. It is found that the actual use time of natural ventilation system tends to decrease and that the designers need to keep contact to the building managers and check whether the system run without problem for long time after it starts to be operated. Sustainable operation was discussed in this paper.

     概要を見る

    The current status of Japanese office buildings is taken as an example and the balance of environmental concerns and office productivity are discussed. To promote the effort for energy conservation, it is important to estimate the indoor environmental quality from the aspect of office workers' productivity. Our experiments on the effect of moderately high temperature on productivity are noted. They showed that the effects of thermal environment on task performance were contradictory among the task types. However, the subjects complained of the feeling of mental fatigue more, and more cerebral blood flow was required to maintain the same level of task performance in the hot condition than at a thermal neutral condition. For evaluating task performance, the cost of maintaining performance, namely, fatigue and mental effort, is important in evaluating and predicting productivity. For long periods of exposure, indoor air temperature has effects on workers' performance.

    ATMOSPHERIC ENVIRONMENT   41 ( 15 ) 3139 - 3150  2007年05月  [査読有り]

     概要を見る

    This study reports results from two different experiments examining reactions between ozone and common building materials that can lead to the formation of secondary products and particulate-phase materials. Monitored species include sub-micron particles and volatile organic compounds (VOCs). In the first set of experiments, various building materials were placed in a 20 L stainless-steel chamber and exposed to ozone. The materials included expanded polystyrene, a natural rubber adhesive, cedar board, Japanese Cyprus board and silver fir board, as well as d-limonene, which is a known constituent of certain woods and cleaning products. The combination of ozone and either d-limonene, cedar board or cypress board produced sub-micron particles, with most of the increase occurring in the size range of 0.01-0.5 mu m diameter. This was not observed for the other materials. In the case of cedar board, the consequence of ozone exposure over an extended time interval was monitored. As the exposure time elapsed, the concentration of sub-micron particles moderately decreased. In the second set of experiments, unwaxed or waxed plastic tiles were placed in the 20 L chamber and exposed to ozone. Sub-micron particles and organic compounds were measured during the course of the experiments. In the case of the waxed tile, the number of 0.0 1-1.0 mu m size particles grew about 50 x 108 particles m(-3); particle growth was significantly less for the un-waxed tile. For both the waxed and un-waxed tiles, the emission rates of heptane, nonane, nonanal, and decanal increased after ozone was added to the supply air. (However, it is not clear if some or all of this production was due to ozone reacting with the sorbent used for sampling or with compounds captured by the sorbent.) This study provides further evidence that ozone-initiated reactions with building materials can be a significant source of both sub-micron particles and secondary organic compounds in indoor environments.

    The impact of the work motivation on the occupants' work performance of serial one-figure addition task and proofreading task was studied in two conditions, i.e., the condition A under cool condition (22℃) and the condition B under neutral condition (25℃). During the occupancy of 120 minutes under each condition, the subjects performed the above tasks with financially motivated situation and without motivated situation. The subjects also answered the questionnaire, which asked the indoor environmental quality and sick building syndrome symptoms during the conditions. It was found that there was significant difference in the performance of theses two tasks between the motivated situation and the non-motivated situation. Under the motivated situation, the performance curve of the addition task performed under condition A and that under condition B were alike in shape. The shape of the performance curve under condition A with non-motivated situation was similar to those with motivated situation. The performance of addition task was well correlated with the thermal acceptability vote for the motivated situation. On the other hand, the good correlation was not found between the performance and thermal acceptability for the non-motivated situation.

    In Korea, sick house syndrome has been a major social concern recently. From May 2004, Indoor Air Quality Management Act regarding public buildings and newly built apartment buildings has been being enforced in Korea. Korean government supports researches on the actual conditions of this subject and makes efforts to regulate indoor air pollution. This study has been conducted to understand the present state of indoor air pollution by chemical pollutants in newly built Korean housing. Including two model houses, seven newly built houses were surveyed in January and in June. Investigation was conducted on indoor air concentration of chemical pollutants, passive flux from building materials, ventilation rate, temperature and relative humidity. We used a passive measurement methods developed by us, which are composed of passive diffusive samplers, ADSEC (Advanced Diffusive Sampling Emission Cell) for passive flux, vials containing PET for ventilation rate. In all of the surveyed houses except model houses, the concentrations of formaldehyde and VOCs which main ingredients were toluene, methylbenzene and xylene were high and exceeded the guideline value of Japan. The air exchange rates were 0.2〜0.3 ACH under the closed windows and without mechanical ventilation operation according to the indoor air standard sampling method in newly built apartment buildings.

     概要を見る

    This study discusses the reasons for the inconsistency between the glass and the acrylic desiccator methods which have been used in Japan to classify building materials for the emission rate of formaldehyde. Evidences from experiments showed that the theoretical equations used in the glass desiccator method were not applicable to the acrylic desiccator method. Three-dimensional models for the two desiccators were built for numerical calculations to analyze emission, diffusion and absorption associated with the desiccator methods. The results showed that the time to reach the steady state in the acrylic desiccator method is much long which deviates from the conditions of the equations to apply. Smaller exposed area of the testing materials and larger volume of the desiccator in the acrylic desiccator method are included as the major factors for the delay in the formation of steady state.

    Recently, indoor air pollution caused by volatile organic compounds (VOCs) from building materials is known as sick building syndrome or multiple chemical sensitivity. As the countermeasure for this indoor air chemical pollution problems, building code was amended in 2002 and it was enforced in 2003. Labeling system of building material corresponding to formaldehyde emission rate is also started in Japan. Although the emission rate measurement with small test chamber based on JIS A 1901 has already been conducted, the existing methods for emission rate measurement require large-scale instruments and they are not always suitable for measuring a large number of building materials. This paper reports the results of numerical analysis of VOCs emission rate from building materials in various passive type flux measurement cell and the performance of these cells are to be clear. Furthermore, in order to supplement the emission rate data from various passive type flux measurement cell, we propose the index of effective diffusion length scale, 'L_d" and report on the analytical results.

    In this study, office work productivity was evaluated by performance and fatigue. Experiments were conducted under Task and Ambient Lighting (TAL) system, to examine the effect of controlling illuminance level on work desk with task lights. Twelve male subjects were exposed in the experimental chamber conditioned at 25℃, 40%RH, and 700lx. Three conditions were compared, which were 700lx under Ambient Lighting system, 700lx under TAL system with controllable task lights, and 700lx under TAL system with uncontrollable task lights. When the subjects could not control the task lights, performance was significantly lower than that when they can control the task lights. Although there was no significant difference on the complaints of fatigue between controllable and uncontrollable task light, the correlation between fatigue and performance showed that 10% increase of complaints on fatigue might result in 6.5% decrease of performance. We also calculated the cost effectiveness of productivity in the case of this experiment. The cost effect increased by performance improvement was big because of the high personnel cost. The individual control system in the light environment was cost-effectiveness.

    Subjective experiments with a desktop based task conditioning system were carried out to investigate the benefits of system in an office like chamber. The experiments were conducted under three different combinations of ambient air temperature and relative humidity, (1) 27℃/40%RH, (2) 30℃/40%RH, and (3) 30℃/70%RH. Each of 16 college age subjects was exposed to the three different experimental room air conditions. There were six supply air flow patterns for task air conditioning, which parameters included isothermal air flow and non-isothermal airflow with three different air velocities. Setting of task condition was fixed at first, and then the subjects were allowed to control the environment freely after certain period in the subjective experiments. Thermal sensation, airflow sensation, and other variable were investigated. The way the subjects controlled the task system was also monitored. It was considered that the task conditioning system could keep subjects thermally comfortable with their ambient temperature higher than condition without it. Questionnaire responses under the 'preferred air' condition revealed the importance of adjustment of task conditioning.

    Synopsis : A modified 65MN(Multi-Nodes) thermoregulation model is tested for the evaluation of the skin temperature distributionin each body part under solar radiation. The present model can be also applicable for the coupled analysis of CFD and radiation. Skin surface temperature distributions predicted by this model are compared with those by subjective experiments in the real scale experimental atrium under solar radiation. Predicted each skin surface temperature almost corresponds to that of subjective experiment with the accuracy around 1 degree Celsius difference. However, the prediction accuracy on the legs and arms is poor by comparison with that on other body parts, which must be required the improvement of prediction accuracy on the legs and arms. As a whole, the present model is a useful tool for the prediction of skin surface temperature distribution under solar radiation.

    Subjective experiments with a non-isothermal task conditioning system were conducted to investigate impacts of the system on thermal comfort and productivity in a climate chamber of Kanto-Gakuin University. Japan. All subjects participated in 'default condition test: 26℃/50%RH' at first. Then a half of the same subjects participated in 'standard condition test: 26℃/50%RH' and the remainder subjects participated in 'task-ambient test: 30℃/50%RH+TAC', just one week later again separately. Thermal, humidity, comfort sensations, and other psychological factors were investigated. The way the subjects controlled the task system was also monitored. In addition to that, subjective productivity was investigated from the subjective, physiological/mental, and performance assessment points of view. It was considered that the task conditioning system could keep people thermally comfortable even in 30℃/50%RH condition. Local thermal sensation was improved with TAC operation. Subjective symptom voting showed that the TAC operation had advantage to alleviate fatigue compared to the case without it.

    Subjective experiments were conducted both in summer and winter in order to clarify the effects of humidity environment and indoor chemical pollutants on subjective comfort and productivity, and evaluate the seasonal difference of their reactions. Subjects were exposed to the three levels of humidity conditions and two indoor air quality levels performing the simulated office works. Concentration of formaldehyde was lower in low humidity environment. The effects of environmental humidity and indoor air quality on subjective thermal comfort were moderate under thermally neutral conditions in both seasons. Perceived air quality was affected by indoor air quality under the polluted condition and by humidity environment under the clean condition. Irritations of mucous were found under polluted conditions in winter though they were not found in summer. Environmental humidity had larger effects on skin moisture than indoor air quality. Subjective performance was higher under clean condition than polluted condition with same humidity. Subjective performance was higher and their dificulty of concentration was lower under high humidity than that under low humidity in winter. The seasonal differences of eye dryness, BUT and skin moisture were found.

    In January 2003, JIS A1901 on "Determination of the emission of volatile organic compounds and aldehydes for building products -Small chamber method" was published. We have proposed and developed a small chamber for determining chemical emission rates from building materials. In this paper, the performance characteristics of small chamber were examined especially background concentration, airtightness and mass transfer coefficient in the chamber. The performance test method was proposed because that was not clearly stated in related standards. The measurement method for mass transfer coefficient by used the filter paper is applicable for the calibration with the measurement for evaporation-controlled materials. Several small chambers have been used to determine chemical emissions for building materials. However, it is difficult to compare with the result from different chambers. In this paper, formaldehyde concentration with two small chambers was discussed by the relation with loading factor (L) and ventilation rate (n). It was observed that it has possibility to compare with the linear of n/L versus 1/C with used the equilibrium concentration for the segment.

    Emission rates of aldehydes and VOCs from wall coverings and powder type adhesives for wall coverings were investigated by using a small chamber. First, the measurements of emission rates were carried out for 16 types of wall covering materials. It was observed that the emission of formaldehyde from one of the samples was 17μg/m^2h after one day, though that from almost all samples was less than 2μg/m^2h. The emission from wall coverings was much lower than the other building materials like floorings. Next, the measurements of emission rates were carried out for 3 types of powder type adhesives for wall covering materials. The emission for TVOC was very low with around 25μg/m^2h, but one of them for formaldehyde was high with 40μg/m^2h. It was found that all powder type adhesives were not low emission.

    Surface weighting factors of the whole human body for both standing and seated postures are calculated based on the numerical calculation of angle factors for the simple prediction of the thermal radiation field. To verify the validity of these factors, they are compared with previous results by Nakamura or Olesen. As a result, surface weighting factors are different from previous results which are always constant independent of the scale of indoor spaces. Especially, surface weighting factor to the under surface for a standing posture is approximately 4 times larger than that of Nakamura in the small indoor spaces. The position of human body and the scale of indoor spaces have influence on surface weighting factors. In addition, appropriate surface weighting factors are proposed corresponding to the scale of indoor spaces, which enables to the accurate prediction of the thermal radiation field.

     概要を見る

    Thermal comfort for car occupants is important factor for automotive design. We have been developing efficient solar reduction glass for vehicles. We also developed a numerical simulator to predict and evaluate the thermal environment and thermal comfort in vehicles. In this simulation, firstly distribution of solar radiation energy through the glass can be calculated actually, and then temperature and air flow distribution, and human comfort can be computed by a combined analysis of CFD (computational fluid dynamics), thermal radiation and body temperature control model which corresponds to shapes of a vehicle and human body. The thermal environment differences between solar reduction glass and normal glass should be clear, which makes the effects of functional glass clear from the view point of human comfort. We can calculate comprehensive situations and indices of thermal comfort evaluation. Using this simulator, it was confirmed quantitatively that Asahi Glass's solar reduction glass could reduce the air-conditioning power than normal glass in summer condition. Further more, it was confirmed quantitatively that our functional glass could supply more comfortable environment for passengers inside car occupants. This result shows the latest value of automotive glass depending on human feelings. Copyright © 2003 SAE International.

    A small-scale chamber, ADPAC, was developed to measure chemical emission rates from building materials. Measurement results from wall covering adhesive, flooring, and insulation materials were shown in this paper. The test pieces with wall covering adhesives were produced at the day of measurement. First measurement was conducted 15 hours after the production of the test piece, when chemical concentration in the chamber was considered to be steady state. Measurements were repeated after 4, 7, 14, and 28 days. It was found that emission of formaldehyde was observed even for the product indicated of "non-formalin". Emission rates were higher during the first day, but decreased rapidly after 1 or 2 weeks. Flooring materials and thermal insulation material EPS were also evaluated.

    The purpose of this study is to clarify thermal comfort and ventilation effectiveness of displacement ventilation system ia a music hall which requires large outdoor air for the ventilation. Displacement ventilation is characterized by naturally generated stratification in density (thermal) and scalar concentration (pollutant). It was considered appropriate to keep good indoor air quality even if reducing the amount of outdoor air. The black lamp was installed in all seats in order to simulate the heat source from the audience. From the measurement result, the local mean age of air in the respiration point of the displacement ventilation system was about 1/3 of the complete mixing condition. The horizontal distribution of local mean age of air in the occupied zone was little. Vertical temperature distribution in the occupied zone was within an acceptable range, and the horizontal temperature distribution of the hall was almost uniform. It was found that the displacement ventilation system maintained comfortable thermal environment with relatively high air conditioning load, while it kept indoor air quality in the occupied zone within an acceptable range.

    This paper aims at clarifying the influence that the ventilation characteristics have on formaldehyde concentration in a house. The indoor formaldehyde concentration, ventilation rates and routes have been measured using an experimental house. The formaldehyde concentration has been calculated by characteristics of emission rates. It was found that the room in which polluted air flows is higher than that of an inflow of outdoor air. It is important to design ventilation routes into which polluted air doesn't flow. The calculated concentration is consistent with the measurement results excluding the period after being made airtight. After being sealed, the experiment value decreased gently as compared with the calculation value.

    Field surveys were conducted at an office with multinational workers in Japan to investigate the differences in the way groups of occupants perceive the environment under real working conditions. Returned questionnaires, 406 in total, were classified into three groups according to their nationality and sex. Only 26% of workers reported their working environment to be comfortable. A significant neutral temperature difference of 3.1 °C was observed between the Japanese female group and the non-Japanese male group under their usual working conditions. Japanese females reported a higher frequency of sick building syndrome related symptoms compared to other groups. Occupant comfort and reported frequency of SBS symptoms were closely related to deviation of the thermal sensation vote from neutral. The thermal environment was found to be a major factor affecting occupant comfort in the concerned office. Differences in the perception of the indoor environment were negatively affecting the ratings of their working environment. © 2002 Elsevier Science B.V. All rights reserved.

     概要を見る

    To alleviate worker's thermal discomfort in a moderately hot environment, a new cooling vest was designed and proposed in this paper. To investigate the effect of the cooling vest and to collect the knowledge for the design of comfortable cooling vest, subjective experiments were conducted. Two kinds of cooling vests, the new one and the commercially available one, were used for comparison. The new cooling vest had more insulation and its surface temperature was higher than the commercially available one. Experiments were performed in the climatic chamber where operative temperature was controlled at 30.2°C and relative humidity was at 37% under still air. In addition, experiment without cooling vest was carried out as a control condition. The results obtained in these experiments were as follow: 1) By wearing both types of cooling vest, the whole body thermal sensation was closer to the neutral conditions than those without cooling vest. This effect was estimated to be equal to the 5.7°C decrement of operative temperature. The subjects felt more comfortable with the cooling vest than without it. They felt more thermally acceptable than that without cooling vest. Wearing the cooling vest was useful to decrease the sweating sensation. 2) The local discomfort was observed when the local thermal sensation was "cool"∼"cold" with the cooling vest. 3) The new cooling vest kept the skin temperature at chest at about 32.6°C. On the other hand, by wearing the commercially available one, it lowered to about 31.1°C. By wearing the new cooling vest, there was a tendency that local thermal sensation vote was higher and local comfort sensation vote was more comfortable than those of the condition wearing the commercially available one. It is important for the design of a comfortable cooling garment to prevent over-cool down from the body.

It was found that the differences of air temperature between normal glass glazing and functional one are not so much but the differences of human feeling are significant. Further more, the effects of functional glass on the reduction of air-conditioning power are simulated. This simulator was a useful tool for investigating the thermal environment differences between solar reduction glass and normal glass clear, which enable to make the effects of functional glass clear from the view point of thermal comfort.

    Six seasonal surveys were conducted to investigate the characteristics of indoor environment and occupant comfort in a high density heat load office building with multi-national workers. Horizontal air temperature difference of 4.6℃ was observed on the same floor. Indoor air quality was generally within the existing level of IAQ standards. Occupant comfort and reported frequency of SBS related symptoms were closely related to thermal sensation votes. A significant neutral temperature difference of 3.1℃ was observed between Japanese female occupant group and non-domestic male group. The thermal environment was found to be a major factor affecting occupant comfort in the concerned office.

    Volatile organic compounds (VOC_s) and carbonyl compounds emitted from the preformed cellular plastics thermal insulation materials were measured to investigate the emission mechanisms. The emission tests were performed under 30℃ atmosphere by using the Field and Laboratory Emission Cell (FLEC). VOC_s and carbonyl compounds were determined qualitatively and quantitatively by a gas chromatography-mass spectrometry (GC/MS) and a high performance liquid chromatography (HPLC). The thermal insulation materials tested in this study were classified into four types, namely extruded polystyrene foam (XPS), expanded polystyrene foam (EPS), polyurethane form (PUF) and phenolic resin foam (PRF). EPS emitted styrene and toluene at emission rates ranged from 100-340 and 93-430μg/(m^2 h), respectively. These emission rates showed a good correlation (r=0.909) with densities of materials. XPS emitted low-boiling point compounds such as chlorometh-ane, chloroethane, bromomethane, or bromoethane, and showed emission rate ranged from 2300-6500, 7600-19000, 110-490 or 73-430μg/(m^2 h), respectively. The emission rates of styrene from XPS were 7.2-84μg/(m^2 h). PUF emitted 1,1-dichloro-l-fluoroethane (HCFC-141b) and showed emission rates of 790-890μg/(m^2 h). PRF emitted dichloromethane and showed emission rates of 1300-2100μg/(m^2 h). Emission rates of HCFC-141b or dichloromethane from the internal part of material were ranging from 55-77 or 4.9-5.2 times, respectively, as each surface emission rate. Emission of carbonyl compounds such as formaldehyde or acetaldehyde was not detected from all materials we tested. The field emission measurements were performed using FLEC at various places in a newly built house. It was observed that the surface of floor, ceiling board and tatami mat emitted styrene, and these emission rates were 19, 32 and 12μg/(m^2 h), respectively. It was suggested that these places emitted styrene through the thermal insulating materials (EPS), because flooring, ceiling and tatami are close to EPS and moreover tatami mat was a so-called "polystyrene tatami".

    The purpose of this paper is to investigate the influence of the environmental factors upon the concentration of formaldehyde using small chambers and to develop a prediction method of indoor air quality in houses. The results of the measured emission rates in the small chambers are asfollows. 1. The emission rate increases as temperature rises and its influence is larger than those of the other factors: the humidity, the ventilation rate, the concentration and the sink effect. 2. The emission process influences upon the emission rates and the process is influenced by these factors. 3.

    In order to study the behavior or the emission of hazardous air pollutants (HAPs) in a newly built house, HAPs were measured at various places in residential air. In this investigation we used three different kinds of sampling method: that is, USEPA method TO-11 and TO-17 as an active sampling method for HAPs in residential air, DSD-carbonyl as a diffusive sampling method for carbonyl compounds in a closed space and FLEC (field and laboratory emission cell) as a chamber method for the determination of emission rates from building materials. As a result, the following was clarified. (1) In the newly built house before moving, the concentrations of toluene, formaldehyde, acetone and CFC-11 were higher than other compounds. (2) 1,4-dichlorobenzene and 1,1,1-trichloroethane were carried into the house by residents. (3) The emission rates of formaldehyde, acetone and CFC-11 were rapid and a wall cabinet in the kitchen emitted those compounds. (4) The concentration of formaldehyde, acetone and CFC-11 in indoor air was directly proportional to the room temperature. (5) It was recognized that the material of a wall cabinet in the kitchen emitted styrene and benzaldehyde and emission rates of those compounds were 470 and 200 μMg/(m^2 h), respectively. (6) Styrene and formaldehyde are remarkable compounds because their concentrations were very high (max 72 and 390 μg/m^3, respectively) and they are known to increase the risk of asthma and cancer.

    A numerical simulation method is proposed for predicting the effective radiation area and the projected area of human body for any postures. This method is based on the solar heat gain simulation. To confirm the validity of this method, predicted effective radiation area factors and projected area factors for both standing and sitting postures are compared with those by the measurements. It was found that predicted figures are met quite well with those by the subjective experiments within 10% accuracy. The effective radiation area and the diagrams of the projected area factors for a person sitting on the floor are illustrated.

    Thermal insulation of clothing is usually measured using a standing thermal manikin. In real life, however, people often sit on chairs and thermal insulation of the nude skin surface and that of clothing should be affected by the chairs. The purpose of this study is to determine the effects of chairs on thermal insulation of the nude skin surface. Seventeen chairs, usually used in an office, were selected for this study. A thermal manikin was used for the thermal evaluation of the chairs. It was found that the area of the back of the chairs influenced the thermnal insulation of the manikin in general and the thermal insulation of the back of the manikin in particular as well as the contact area between the chair and the skin surface.

    Thermal environments, indoor air quality, and ventilation effectiveness were measured and evaluated in an office installed both with floor-based and ceiling based systems. Two systems were compared. Major findings are as follows : 1. The horizontal air temperature gradients were within acceptable range and almost same for both systems. 2. The LPPDs were found less than 6% except 6.25% for ceiling-based system in summer. 3. Air temperatures and Δ EHTs at lower level with floor-based system tended to be cooler than those for the ceiling-based system. However the differences were not significant. 4. Subjective acceptability for indoor air quality was no difference between two systems. However lower figures were observed for floor-based airconditioning system in terms of the concentration or the number of air-born particles. 5. Ventilation performance index was greater for the floor-based system than the ceiling-based system. This field study quantitatively makes it clear that floor-based system can provide comparable thermal environment and better air quality in comparison with the ceiling-based system.

    1.はじめに 全面床吹出置換空調方式は置換換気システムの一種である。換気効率が高いため、熱的快適性と省エネルギー性の点から注目されているが、温度成層を形成するために上下温度差が問題となる場合がある。垂直温度分布には室内熱負荷総量だけでなく熱源位置も影響を与えると考えられる。本研究では、OA化により内部負荷が種々の状態で配置されているオフィス空間に全面床吹出置換空調方式を適用した際の室内温熱環境および人体の熱的快適性を実験により評価することを目的としている。2.実験方法 実験は1996年の夏季に奥行き16m、幅6m、天井高さ2.7mのオフィス空間1スパン分を模擬した環境試験室にて行われた。内部チャンバー全面には通気性タイルカーペットと多孔OAフロアを敷設してあり、二重床内プレナムを通った空調空気はカーペット内部で面状に拡散し室内にほぼ均一に給気される。内部チャンバーからの排気は天井に配したダブルTバーの排気スリットを通して行う天井レタンチャンバー方式とした。また、窓の外側の外気室には夏季および冬季の外乱を再現するための空調システムおよび人工太陽灯が備わっている。室内温熱環境が定常に達した後述の14条件について1)移動測定カート、2)熱電対による温度分布、3)サーマルマネキンによる測定が行われた。移動測定カートは7項目の環境要素を同時計測可能なカートで、負荷分散条件については窓面からの距離1.0/1.5/3.0/4.5/6.0/9.0/12.0/15.Om、負荷集中条件については1.0/1.5/3.0/4.5/6.0/7.0/8.0/9.Omの地点にて測定を行った。また、室内上下温度分布は7地点、高さ8点にて全実験中ロガーにより記録された。サーマルマネキンによる皮膚温の測定は窓面を正面として椅座位にて3地点で行った。3.実験条件 室内負荷は照明負荷(100W×16)とアルミの筒で覆った電球を用いた室内模擬負荷(100W×10、20)により26W/m^2、36W/m^2とした。また、熱源の高さ(0.2、1.0、2.Om)、配置(分散、集中)、給気風量(1890、1350、810m^3/h)、ペリメータ負荷(無、有-夏季、冬季)を変化させることによって14条件について測定を行った。負荷の配置は、熱源分散時は模擬負荷を2列にわけて均等に配置し、集中時は窓面より8mの地点に集中させた。夏季を想定した条件では外気室温度を32℃、ガラス内側のブラインドが受ける放射熱量を580W/m^2とし、冬季は外気室温度を0℃とした。給気風量は一定とし、室内の代表点(出入り口側の壁面近く、高さ1.1m)で空気温度25.5℃となるように吹出し温度を自動制御した。4.結果 実験は36W/m^2、26W/m^2の2種類の内部負荷で行われたが、空調機の給気から室内排気までの空気温度差により算出された除去熱量はこの熱負荷とほぼ一致した。室内に給気される直前である室内側床表面に至るまでに全処理熱量の50〜60%が処理された。これは床全体が冷却されて床下への熱貫流が発生したためと考えられる。負荷を分散させ、高さを変化させた場合、上下温度分布より部屋全体を通じてほぼ一様に温度成層が広がっていることが分かった。また、負荷高さにより温度勾配の不連続点に変化が見られた。これは負荷位置にて暖められた温度の高い空気の層が上部に形成されるためである。すなわち熱負荷の高さが低いと居住域での上下温度差が大きくなり、逆に高いと温度差は小さくなる。室内負荷の増加によりいずれの条件についても上下温度差は大きくなったが、高さ0.lmと1.1m間の温度差は、最も上下温度分布がつくと予想される「36LS-7」で最大2.1℃となった以外は1.5℃以内であった。給気風量を減少させると上下温度差は大きくなり、810m^3/hのときには室内負荷を全て除去できずに全体の室温が上昇した。給気風量1890m^3/hにて熱負荷の高さが1.Om(M)、または2.Om(H)で分散している場合、床表面における無次元温度(Tf)がおよそ0.5となり、その点と室温制御用サーモスタットの置かれている高さ1.1mでの空気温度、天井吸込口での排気温度の3点がほぼ一直線上にあることがわかった。給気風量が減少すると給気温度が下がるために床面の無次元温度が相対的に高くなるが、同様に3点は一直線上であった。しかし、熱負荷高さが0.1m(L)と低い場合は室下部での温度上昇が激しいため直線にはならなかった。熱源を窓面より8mの地点に集中させた場合、集中点に近づくにつれ0.3〜0.5℃の室温上昇が見られたが、温度勾配は室全体を通してほぼ一定に保たれた。負荷集中点のそばにおける高さ0.1mと1.1m間の垂直温度差も1.0℃以内となった。空気の水平拡散性が大きく、水平方向の温度分布が室内全体を通してほぼ均一となったためと考えられる。熱源を分散させた場合でも室中央部にて若干の空気温度上昇が見られたが、これは本システムの給気方法の特性によるものであると考えられる。夏季条件では窓面近くの床が放射で暖められ、温度成層が乱れた。また、冬季条件では窓面近傍にてコールドドラフトの影響が見られたものの床上0.6m以上での温度成層は保たれていた。温熱快適性を保ちつつ置換換気の効果を得るには適切なペリメータ処理が必要であると考えられる。冬季条件を除くすべての条件について気流速度は0.1m/sを超えることはなかった。冬季条件では窓面近傍でコールドドラフトにより0.15m/sまでの気流速度の増加が見られたが、いずれの条件についてもISO-7730やASHRAE55-92の基準値以内に抑えられていた。代謝量1.1met、着衣量0.6cloとして計算により求めたPMVの値は夏季、冬季条件を除いて0から0.5の範囲内であった。さらに詳細な居住者の熱的快適性を調査するためにサーマルマネキンの皮膚温測定が行われた。周辺空気温度および放射の影響が皮膚温に大きな影響を与えることが確かめられた。5.結論 本方式では床パネルによる床冷却効果により居住域における温度勾配が小さくなった。熱源の高さが低いほど居住域における上下温度差が大きくなり、内部負荷の増加及び給気風量の減少も大きな温度差を生む結果となった。熱源を集中させると0.3〜0.5℃の空気温度上昇が見られたが温度勾配は全室内を通してほぼ一定に保たれていた。夏季条件では窓面近傍の床が暖められ、室全体の温度成層が乱れた。冬季条件では窓近傍にてコールドドラフトが確認されたが、高さ0.6m以上での温度成層は保たれていた。サーマルマネキンの皮膚温に周囲空気温度および放射の影響が強く見られた。

     概要を見る

    Results of laboratory measurements on the thermal performance of the floor-supply displacement ventilation system in comparison with a displacement ventilation system with sidewall mounted diffuser and a ceiling based distribution system are described. The experiments were performed in a controlled chamber configured to resemble a modern office space with modular workstation furniture and partitions. In addition to detailed measurements of temperature, air velocity, and tracer gas concentration, a skin temperature controlled thermal manikin was used to evaluate the non-uniformity of thermal environments produced by these systems. Thermal stratification was observed in both of the displacement ventilation systems which produced greater air temperature differences than the ceiling based system. Under the conditions of the appropriate supply air volume against indoor heat load the displacement ventilation systems could be operated to maintain acceptable thermal comfort and high ventilation efficiency in the occupant zone of the space, at the same time taking advantage of the temperature stratification to achieve energy savings in air conditioning.

     概要を見る

    The purpose of this study was to evaluate thermal comfort properties of surgical gowns made of dual functional finish cotton and nonwoven fabrics which have barrier properties of blood and micro-organism. Four types of surgical gowns, which were made of nonwoven fabrics with finish or without and were made of cotton with finish or without, were tested. The thermal insulations of four surgical gowns were measured with thermal manikin. Subjective experiments on thermal comfort, skin temperature and clothing microclimate were conducted. Six male subjects, between 26 and 28 years age old, participated in the wear trials tests. Typical activities for surgeons in the operation theater were simulated during the experimental sessions. Air temperature in a climate chamber was kept at 22℃ and its humidity was 60%RH. Air velocity was controlled at less than 0.15 m/s. Inner radiant temperature was almost equal to the air temperature. Basic thermal insulation of the dual functional finished nonwoven surgical gown was 0.87 clo, which was slightly higher than that of untreated (0.84 clo). However, the skin temperature of the subject wearing a dual functional finished surgical gown was significantly lower at P.05. When the subject wears the dual functional finished gown, the amount of sweating was less than that when wearing untreated. Microclimate temperature and humidity of dual functional finished surgical gown were lower than untreated and it was statistically significant. There was no significant difference in subjective humid and overall comfort sensation between finished and untreated ones. Thermal sensation of dual functional finished one was significantly different from untreated one only during the first exercise. The results of this study indicate that the dual functional finish surgical gown allowed heat to be transferred from the skin of subject to the atmosphere better than untreated. The nonwoven surgical gown showed no difference in comfort properties from cotton one.

    The purpose of this study is to examine the effects of body posture on thermal insulation of clothing. Clothing ensembles including skirts were mainly investigated. A new thermal manikin was developed for this study. This manikin was able to change her body posture without increasing or decreasing her surface area. By changing posture from standing to seated, the total thermal insulation of clothing (It) was decreased by around 1.4%. The surface thermal resistance at nude (Ia) was increased by 8%. As a result, the basic thermal insulation of clothing (Icl) was decreased by 14%. The main reason for the decrease of basic thermal insulation (Icl) when the posture of thermal manikln changes from standing to seated was the increase of la at nude. The total thermal insulation of clothing for each body posture (Iti), when standing and seated, were compared. The parts affected by the changed posture were abdomen, hip and thighs, and especially under the skirt of 61cm length, the knees were most affected.

    A comparative analysis is presented on the three conventional methods and our new one for evaluating the basic thermal insulation of cloting. A thermal manikin regulated at constant temperature over all parts was seated on a chair and, in the steady state, the environmental temperature, the amount of heat which the manikin lost, and the local skin temperature at nineteen points were measured for various clothing ensembles covering the body. From the data obtained were estimated the thermal insulation only by the skin when the manikin was unclothed and that by the total when clothed; based on these the basic thermal insulation of each clothing was evaluated by the current methods as well as ours and the results were compared. An investigation also on the role of the insulation by the outer clothing surface revealed that, if it was neglected, greater errors might be caused in estimating the basic thermal insulation of clothing.

    標準夏服,セー夕一組合わせ衣服,ウインドブレーカー組合せ衣服の気流速度増加による着衣熱抵抗の減少に関する実験結果に関して述べている。熱的に19分割された椅座位のサーマルマネキンを0.1, 0.22, 0.32, 0.48, 0.69, 1.0, 1.4m/sの気流速度下に曝露した。標準夏服の場合,作用温度は27℃とした。また,セーターとウインドブレーカー組合せの場合,作用温度23.3℃とした。静穏気流時05.cloの標準夏服の基礎着衣熱抵抗は風速1.0m/sで25%減少した。セーター組合せの基礎着衣熱抵抗は,気流速度増加によりウインドブレーカ組合せ衣服より大きく減少した。着衣熱抵抗の減少を考慮に入れた等価温度がサーマルマネキンの熱損失に基づき導き出された。気流を透過する衣服では,従来の等価温度より気流の冷却効果があることが示された。

    OA化に伴う熱負荷の偏在化, オフィスワーカーの個人差のため, 均一温熱環境をつくりだすのみで快適環境を実現することは難しくなっている. 本研究では, オフィスや居住空間において温風暖房によって発生した上下温度分布による不快を減少させることを目的として, パーソナルふく射暖房パネルの体感効果に関して報告する. 体感実験の結果, パーソナルふく射パネルは下肢の冷えを解消する効果があるが, パネル表面温度が高くなると気流速が増加し, 局部温冷感による不快感を生じる可能性があることが明らかになった. また, パネル表面温度が高温にならないように注意し, 他の暖房方式との併用によって, より快適な居住空間を形成することが必要であることがわかった.

     概要を見る

    A method to quantify the amount of tobacco smoke adhered on the surface material is proposed and the results of odor sensation experiment on adhered tobacco smoke using subjects are presented. First, we developed a new technique to quantify adhered tobacco smoke based on infrared spectroscopy. The experiment boxes were filled with different concentrations of tobacco smoke and after 14 hours tobacco smoke in the box was pulled out by ventilation. Then the subjects were asked to judge the intensity and acceptability of the odor of the air in the box. The odor in the box with a small amount of tobacco smoke adhered on the surfaces caused more than 60% of dissatisfied with one air change per hour. And it was showed that substance from tobacco smoke was adhered on the floor more than other surfaces. As results of field investigations we found that not only levels of tobacco smoke decides the amount adhered in the actual spaces.

     概要を見る

    The purpose of this study is to investigate the indoor air quality by making subjective assessment of perceived air pollution caused by human bioeffluents. One hundred and seven subjects were used as panel to report the odor intensities and acceptability of bioeffluents from fifty-four other subjects as occupants. It was found that 20% of judges described dissatisfaction caused by bioeffluents at 1.5 on the Yaglou's odor intensity scale. A ventilation rate around 7 liters per second per person was required to satisfy 80% of judges entering the chamber. In addition, the relationship between the ventilation rate per olf and the percentage of dissatisfied judges for Japanese subjects was investigated.
