建築設計における意思決定の判断材料として、環境影響評価の提示が求められている。しかし、現在多用されている建築学会の『建物のLCA指針』（LCAツール）
では、原燃料別にエネルギー消費量、CO2排出量等の推計ができないため、詳細な環境影響評価が難しい。よって本研究では、最新(2005年)の産業連関表と各種
統計資料を用いてインベントリ項目を原燃料別に細分化する。

The purpose of this study is to clarify the effect of illuminance and color temperature on human productivity and lighting satisfaction. In this study, we performed a laboratory experiment. To evaluate lighting satisfaction, subjects responded to a questionnaire, and to evaluate objective performance, subjects performed four tasks involving information processing and creative activity. Seven combinations of 3 illuminances (375 lx, 750 lx, 1200 lx) and 3 color temperatures (3000 K, 4000 K, 5000 K) were investigated. Combinations of illuminance and color temperature that maximize objective performance differed by task. The regression equation (r = 0.55) states that when lighting satisfaction is increased, the relative performance of office work will also increase. The regression can calculate and relative performance of office work from lighting satisfaction vote of occupants.

We have conducted field measurements and a questionnaire survey, and statistical analysis of the results, in order to review applicable criteria for assessing the thermal environment in school classrooms without air conditioning. From survey results for both summer and winter, we found that the indoor-outdoor temperature difference is more strongly correlated with students' thermal sensations in classrooms than the predicted mean vote index: the correlation coefficient is 0.979 in summer and -0.992 in winter. These results indicate that the indoor-outdoor temperature difference is a valid criterion for assessing the thermal environment of classrooms. In addition, taking the indoor-outdoor temperature difference as the explanatory variable and the index of the students' thermal sensations as the objective variable, we performed a logistic regression analysis. As a result, formulas for predicting students' thermal sensations in classrooms were derived. These findings should be beneficial in establishing an appropriate learning environment for students.

Field measurements were conducted in a nursing home located in the hot and humid city of Kumamoto, Japan, between July and September 2010. In addition, a questionnaire survey was conducted with care staff during the measurement procedure to evaluate the effect of the thermal environment on thermal comfort and productivity. Results indicated that radiant cooling and heating system provided a stable temperature. Furthermore, the system coefficient of performance was calculated to evaluate the performance of the radiant cooling system and was 1.8-3.1. As a result of the questionnaire survey, about half of the staff were satisfied with the current thermal environment in the facility, reporting that it was comfortable and did not reduce working efficiency.

建築分野の低炭素化に向け、建築物の設計段階におけるLCA (Life Cycle Assessment)が資材選定の判断材料として非常に有効である。そこで本研究では、最新の2005年産業連関表を用いて、建築物用のLCAデータベースを構築した。輸入依存度の高い石炭、原油、天然ガス、鉄鉱石、アルミニウム（新地金）、素材、製材、合板の8品目に関しては、海外での生産活動から海上輸送までの環境負荷物質排出量を現地調査・文献調査に基づきを推計した。
