"A Coupled Simulation of Heat and Air Flow" is expected to be the computer aided design tool in outdoor space. Compared with the existing available prediction methods, this method herein described places greater emphasis on its ability to make it possible to evaluate thermal radiant environments, air temperature and wind distribution that are given to the timely prediction in design process as well as to various other factor including both variety of external materials and variety of exterior shapes. This method was developed based on sensible heat balance simulation for all the exterior surface and standard k-ε turbulent Model. And sensible heat balance simulation is also combined with 3D-CAD system that makes it easily to input the complicated exterior shape and also make it possible to evaluate the 3-D distribution of surface temperature at any view points.
