A research on the designing of energy-saving roofs of residence building in Hunan Province

The thesis emphasizes in analyzing the thermal environment of top-floor rooms and energy consumption of various roofs. Through the application of the mathematical model based on DOE-2 software, the author simulates and calculates the thermal environment of top-floor rooms and energy consumption of various roofs for seeking the roofing type and the roofing structure that harmonize with the climate of Hunan Province, and discussing the energy-saving and ecological function of the application of energy-saving roofs in Hunan Province. The author aims at improving the poor thermal insulation quality of roofs that widely exists in Hunan for a long time as to supply reference for the designing of the roofs of residence building in Hunan.
