The light source models All Sky Models reproducing daylight and solar radiation comprehensively are installed to ray-tracer RADIANCE calculating inter-reflections with reflection distribution accurately. Furthermore, a program converting the irradiance distribution to heat boundary conditions of CFD analysis is developedrnIn this paper, the developed programs predicted the daylight illuminance, radiation load and irradiance distribution with inter-reflection of shades, and energy saving effects of artificial lighting and air conditioning was evaluated under the same analysis method. Then, applying CFD analysis the difference was found in the temperature distributions under the heat boundary conditions of irradiance distribution between the calculation by the developed programs and the calculation by the easy method. As a result, the availability of the programs is indicated.%本論文では、庇の設置位置が省エネルギー効果と光と温熱の室内rn環境に与える影響について検討した。rnその結果、可視光と日射の光源モデルを統合的に扱うAll SkyrnModel-LとAll Sky Model-Rを、相互反射や部材の反射指向性を考慮rnした計算が可能なRADIANCEに組み込んだプログラムによる計算rnが、詳細な昼光照度の分布や日射負荷の予測を可能とし、実現象のrn再現性が高い省エネルギー性の比較検討に適用可能であることがrn示された。
