Energy Conservation Reconstruction Study of Existing Apartment Buildings in Hot Summer and Warm Winter Area—A Case Study of Apartment Building in Xiamen University

Abstract

In order to study the energy saving and emission reduction of existing student apartments in hot summer and warm winter area, and based on the dynamic simulation analysis software of building energy consumption and the reconstruction experience of building energy saving at home and abroad, and combined with the characteristics of climate and environment in Xiamen, where is located in hot summer and warm winter area, and through selecting the more energy-saving material and establishing the dynamic simulation model to simulate the apartment internal thermal environment, and then it can be drawed that the comparative analysis of energy conservation before and after the reconstruction. Research shows that improving energy-saving performance of the roof, wall and window glass can better reduce energy consumption and achieve the purpose of energy conservation. At the same time the paper puts forward relevant suggestions for building energy efficiency design and existing building energy saving and provide reference for energy conservation.
