Abstract
In urban area, large amount of anthropogenic heat affects the heat environment in ravines of buildings. In order to predict the heat environment in urban areas minutely, an ‘urban canopy model’ was developed which can predict the air temperature in ravines of buildings. This model was connected with the numerical model for predicting wind and atmospheric temperature distribution three dimensionally developed by authors.
The numerical simulation on Tokyo 23 wards in a tropical day showed that the air temperature in ravines of buildings in central Tokyo tends to be high in addition to inland area of Tokyo 23 wards in daytime. It was found that, in ravines of buildings, the anthropogenic heat affects the air temperature more sensitively than the temperature above roofs of buildings.
