抄録

Shading device is effective for reducing radiation load of buildings. Radiation load of buildings considering sky radiance distribution is different from that by isotropic model. RADIANCE is ray-tracing program and its accuracy is evaluated by some previous researches. In this research, RADIANCE installed sky radiance distribution model All Sky Model-R was developed. The transmission characteristics of external blinds evaluated by RADIANCE with isotropic model are compared with that with distribution mode in each sky conditions. Prediction error of annual insolation of building with external blinds by isotropic model is evaluated on the basis of that by sky distribution model. The evaluation results are introduced in this paper.
