Abstract
This study's purpose is to clarify the effects of differences between greening conditions on building sites, roof-tops and walls of buildings on the thermal environment using CFD (Computational Fluid Dynamics) analysis, and with the Kasumigaseki district in Chiyoda-ku, Tokyo as the model. As a result, the quantity of total sensible heat flux, was 24% lower in the case of lawn greening and roof-top greening in the district than in the case without greening. In addition, in the case of wall greening at the south and west side of each building, it was lowered by 15%. In this way, the thermal effect of greening of the building site in the actual district could be grasped quantitatively.
