Impact of window shading devices on energy performance of prototypical buildings
Bin Chen, Ying Ji, Peng XuAbstract: External window shading, in its variety of forms, is an important measure for reducing air conditioning energy consumption. How to quickly evaluate and select effective external shading shapes to suit different climate zones and building types is of great significance towards promoting building energy conservation in China. In this paper, firstly, benchmarking models of four prototypical buildings in five climate zones in China are established and calibrated with EnergyPlus. Secondly, four common types of external shading are applied to the established benchmarking models which provide energy-saving rates and economies of the external shading modes in different building types and climate zones. Finally, after a comprehensive analysis of the energy-saving rates and economies, we can determine appropriate external shading devices for different building types in different climate zones, providing a design basis and theoretical support for actual projects.
