Abstract

The land use and artificial heat release from the buildings have to be needed in evaluating the urban or local thermal environment. In this study, a database system for land use and buildings has been constructed automatically by using GIS data. By using the system, the output of land use and heat release can be easily gained at any mesh size. Incorporating those data into the thermal prediction program, the thermal environment in urban or local area can be evaluated. To validate the system presented, an experiment planning, Science and Technology City in Kitakyushu, Fukuoka has selected as a case study. The result has shown the thermal evaluation system is effective. The effect of green area on the mitigation of the thermal environment has been confirmed in the planning. The results also showed that the calculation time and accuracy are significantly affected by the mesh size.
