THERMAL EFFECTS OF BUILDINGS IN AN URBAN CANOPY : Part 1 A numerical model of heat emission from buildings

Abstract

This study aimed at examining causes and effects between the heat emission from buildings and climate changes in an urban canopy. For the first step of the study, a thermal model which focused on the heat emission from a sole building was presented based on a dynamic load calculation method and its extension. The point of the extension is the added description of the heat transfer from interior to the urban side. The results of the case study by the model show that the thermal factor of the building surface such as a wall structure dominate over the time variation of heat emission. In other words, the results imply a possibility of controlling the variation by the thermal design of the building surface.
