Development of support tool for outdoor thermal environmental design of urban/ building using numerical analysis
The purpose of this study is to develop a thermal design tool for architectural designer by combining a heat balance simulation for urban surfaces,including buildings,the ground and greenery,with a 3D-CAD. This tool is constructed by improving the previous s I mu l a t I o n mo d e l,wh I c h u s e s t h e Ge o g r a p h I c Information System for the input data.The simulation algorithm is improved so as to predict the surface temperature distribution of urban blocks while taking into account the actual design of the outdoor space using the 3D-CAD system.A pre-post processing s y s t e m u s I n g a l l -p u r p o s e 3 D-CAD s o f t wa r e I s devel oped.The resul t s obt ai ned by appl yi ng t hi s simulation tool to an area of detached houses reveals that the tool is able to simulate the effects of building s hape,mat er I al s,and t r ee s hade on t he s ur f ace temperature distribution,as well as the MRT and HIP, which are evaluation indexes of the urban thermal environment.
