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 radiance distribution to heat boundary conditions of CFD analysis is developed. In 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.
