Abstract
In this paper, the three dimensional numerical model is developed to predict the heat environment in an urban block in consideration of the effect of each building on wind and radiation. In this model, the time and space variations of velocity, air temperature, air humidity and surface temperature including buildings are evaluated with a horizontal resolution of about 10m. This model is applied to an ideal urban block in order to evaluate the effect of partial greening on decreasing air temperature. Numerical results on a typical summer day exhibit some fundamental knowledge about greening effects concerning with the relationship between the location of greening area and wind direction.
