Numerical analysis of air temperature increases in urban area using the building-urban-soil simultaneous simulation model

The  authors  propose  a  predicting  methodology combined with simultaneous solution for Building- Urban-Soil system to analyze the heat island phenomenon quantitatively in this paper. Using this model, numerical simulation is performed in order to analyze quantitative effects of many factors on the heat island phenomenon. The factors of the heat island phenomenon addressed are: ground materials, geometric urban configuration, artificial exhausted heat release, physical properties of  buildings envelope and mechanical performance of air-conditioning system.
