Design of Sunshade Board with South External Window of Residential Building in Hangzhou Based on Energy Conservation

摘要

Since the resources of the world are scarce and in high demand.Architects should try to decrease energy consumption through appropriate architectural design.Energy efficient architectural design has been a fast growing global trend.Appropriate external sunshade design can effectively decrease building energy during high consumption times,for example when using air-conditioning in the summer.By using software simulation analysis,this research quantitatively analyzes the design of horizontal sunshade board of southern external windows in Hangzhou's residential buildings.Firstly,according to weather conditions and body comfort degree,it various the setting modes and ranges of shaded area.Secondly,comprehensively considering natural lighting and solar radiation,it provides the ideal size of sunshade board.Lastly,taking the texture of the residential building and elevation design into account,it gives suggestions for incorporating sunshade integrated architectural design.Finally,this paper guarantees that the proposed size of horizontal sunshade board and integrated architectural design will decrease energy consumption.
