There are two points of view for the prevention design of moisture problem in the building insulated envelope. One is the strictly prevention of high moisture condition in the insulated wall cavity. The other one is the permission of short-term high moisture condition, condensation and high moisture content of the wooden material as long as keeping physical durability. If the later standpoint were chosen, the insulated envelope design of every variety for Japan would be possible. Nevertheless, there are no criteria to estimate the damage of physical durability of wood by the biological factors related high moisture condition. The points of this paper are as follows; 1) The importance of estimation damage of woods by the moisture problems is describes. 2) 2 case of hygrothermal steady state experiments were done to get basic acknowledge of woods damage by biological factors considering term, water content, temperature and humidity, physical durability.

If the later standpoint were chosen, the insulated envelope design of every variety for Japan would be possible. Nevertheless, there are no criteria to estimate the damage of physical durability of wood by the biological factors related high moisture condition. In the previous paper, we reported about the concept of the prevention design of moisture problem in the building insulated envelope and the relationships between water content and decay various woods under hygrothermal steady conditions. In this paper, the relationships between water content and decay of various woods under two kinds of hygrothermal transient conditions are shown.

New assessment system for buildings known as CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) has been developed. In CASBEE, two environmental aspects i.e. environmental load (L) and quality of building performance (Q) are set as the major assessment targets. BEE (Building Environmental Efficiency) is defined as Q/L, following the concept of eco-efficiency. This assessment structure is the most unique point of CASBEE compared with existing assessment tools. With the increasing BEE value, total environmental performance of buildings is labeled as any of Class C (Poor), B-, B+, A, and S (Excellent). CASBEE is going to provide four tools according to the lifecycle of a building.

「建物」と暖冷房「機器」の両者を踏まえ、快適性と省エネ性を統合的に評価する手法(以下、統合的評価手法と記す)を検討し、提案するに至った。検討にあたって、各種暖冷房方式による温熱環境の差異や実働効率などの機器の稼働状況などの実態を実験・実測により把握し、そのデータを整備した。また、通風による冷房負荷削減効果を予測する上で不可欠となる、建物に作用する風圧力に関するデータベースを風洞実験により整備した。なお、統合的評価手法については、今後も検討・改良を加えていく所存である。An integrated assessment method of comfort and energy saving were investigated, and proposed in this study. This method is based on both sides of "Building specifications" and "HVAC systems". In this investigation of the method, thermal environment by various HVAC systems and actual efficiency of equipments were arranged by experiments and actual survey. Moreover, the data base of wind pressure coefficients of buildings was maintained by the wind tunnel experiment.

本研究では,複雑な事象を総合的に評価する必要がある住宅の温熱環境を対象に,非定常気流・温熱環境解析手法を用いたバーチャルハウスシミュレータの開発を行った。異なる暖房方式を採用した居室の定常・非定常温熱環境の実測を行い,検証用データベースを作成した。実測を対象に各種解析モデルを用いて解析を行い,実測と比較して精度を検討した結果,本研究で開発したシミュレータが住宅の温熱環境評価として実用的な精度を有することを示した。

To clarify the hygrothermal environment of vertical edge insulation methods in moderate and humid climate region, especially in the summer involving the rainy season, temperature and relative humility of 12 houses have been measured. From the measurement results, the temperature variation in the crawl space tends to slide slightly backward compare to the outdoor air. Evaporation from the drying concrete keeps the humidity in the crawl space rather high, especially in the summer just after completion. But it becomes moderate on condition that it passes through the winter. Daily diurnal range of temperature in the crawl space is smaller, and absolute humidity is lower, than the other construction method, that also ensures against condensation proofing.
