Various researches highlight that indoor air quality affects performance of workers in offices. Although good indoor air quality improves work performance, it also increases energy consumption. In this study, we achieved a field survey in a real office in order to investigate the relationship between thermal environment, productivity, and energy consumption. In addition to the monitoring of indoor environmental quality and energy consumption, subjective experiments were conducted. In order to evaluate subjective performance, workers and students responded to questionnaires, and to evaluate objective performance, students simulated three types of office works. By calculating room temperature and worker's subjective performance, we demonstrate the correlation between room temperature and worker's performance (R2=0.22, p

近年中山間地域において環境負荷の増大、少子高齢化に伴う財政状況の悪化、コミュニティの脆弱化といった諸問題が急速に進展しており、多くの集落が存続危機の状態にあると指摘されている。そこで本研究では、地域の持続可能性を環境/経済/社会の側面から評価・予測することを目的とし、環境工学、計量経済学、社会科学に基づいた持続可能性評価モデルを構築した。そして、モデル地域において実際に持続可能性の評価を行った。

It takes many years to recover the initial investment cost for installing housing insulation through savings from energy reduction (Energy Benefit: EB), since construction cost is very high in Japan. This long payback time is the major barrier to the promotion of well-insulated houses. However, it has been found that if Non-Energy Benefits (NEB) of well insulated houses, such as improvement in personal health, reduction of medical expenses and decline in absences from work are all taken into account, the time required to recover the initial investment cost would change from 29 to 16 years. Therefore recognition of NEB is expected to encourage residents to invest in residential thermal insulation. NEB of well-insulated houses is thus evaluated regarding human health in this study.

We have developed assessment systems for buildings known as CASBEE (Comprehensive Assessment System for Building Environmental Efficiency). CASBEE for new construction and that for existing building were already developed and reported in former reports. We have newly developed the assessment system for renovation. Then we would report the outline of it.

In order to clarify the effect of classroom environmental quality on students' health and learning performance, field measurements, assessments using CASBEE-School (Comprehensive Assessment System for Built Environment Efficiency for school), and questionnaire survey for students and their teachers were conducted in 12 elementary schools. From the results of the survey conducted in both summer and winter, a significant correlation was observed between score for Q1 (indoor environment) category of CASBEE-School and students' satisfaction with their classroom in each school, and effectiveness of assessments by CASBEE-School was validated. However, there is still room for further improvement of assessment system in detail. In addition, a significant correlation between students' satisfaction and both of physical conditions and concentration was observed in this study.

Building sector has a heavy role to create sustainable society, because CO_2 emissions associated with construction and operation of buildings are estimated to be 1/3 of the whole CO_2 emissions in Japan. These CO_2 emissions were estimated from 1970 through 2050 and the following results were obtained. (1) CO_2 emission between 2008 and 2012 will increase by 15% than 1990 level. (2) CO_2 emission can be reduced by 6% between 2008 and 2012, and reduced by 40% in 2050, if the 30% energy saving, long life and environment-conscious materials are adopted to new buildings.

CASBEE-UD, a new member of "CASBEE family", is developed to assess the environmental efficiency of planned projects consisting of multiple buildings and public areas. Its particular emphasis is on the outdoor environment and compound function of group of buildings. This tool inherits the general framework of other CASBEE tools, such as the assessment by BEE defined as the quality of buildings performance divided by the environmental load. It enhances well-balanced planning of urban projects, so that it can contribute to the realization of sustainable cities.

被験者実験を行い、入浴時の高齢者に対応した体温予測モデルを開発した。そして本モデルが高齢者の入浴時の体温が精度良く再現されていることを検証した。またインターネットアンケート調査と入浴事故に関する症例データを基に、体温と熱中症リスクの関係の定量化を行った。さらに住宅仕様の改善による熱中症リスク低減効果を明確にすることを目的とし、"住宅仕様"、"入浴方法"、"体温上昇"、"熱中症リスク"の各関係を定量的に把握し、高齢者の入浴時の熱中症リスクを評価した。
