Research Abstract

A passive design support tool considering indoor and outdoor light and thermal environment using numerical simulation was developed. The study results are as follows.(1) Computational algorithms for the prediction of indoor and outdoor light and thermal environment were developed.(2) The tree model for solar shading was developed.(3) The simulation models were integrated with 3D-CAD system and pre-processing method were constructed for practical use.
