Abstract: In this paper, a simulation tool for passive design considering indoor and outdoor radiation environment using a three-dimensional computeraided design (3D-CAD) system is developed. This tool predicts surface temperature distribution on indoor and outdoor surfaces of a building considering the spatial geometry, materials used, and solar shading. A radiation model algorithm with a highresolution voxel model was developed to calculate surface temperature distribution and mean radiant temperature (MRT) distribution while considering the detailed spatial design. The results of the application of this developed tool to a passive design housing using direct heat gain and deciduous tree cover confirmed that this simulation tool is useful for evaluating the effect of passive design on the thermal environment at the design stage.
