Outdoor thermal environment in summer become worse due to a change of land cover and an increase of artificial heat release according to the urban development. In this paper, the authors have developed a new method for predicting the human comfort in outdoor thermal space with the aid of CFD (Computational Fluid Dynamics). Furthermore, the effect of greening on outdoor wind and thermal environment was analyzed. Spatial distribution of SET (Standard Effective Temperature) was calculated in order to assess the pedestrian level comfort using the data given from the CFD predictions. Two cases of predictions were carried out. In easel, green area ratio of ground surface was assumed 10%, while the green area ratio of ground surface was changed to 100% in case2. By comparing the SET* distributions in both cases, effects of greening were thus clarified.
