The Study On The Outer Sun Shading System Energy Consumption Of The Public Building Outer Window

The energy problem is world famous;especially Shanghai as a intemational metropolis,whose important target are develop resource conservation-minded society and environment-friendly society.The public building accounts for a large part in Shanghai's total energy consumption,of which doors and windows are main factors. This issue aims on above problem,that are public building outer window's material, different orientation outer sun shading system and different location of south outer window,analyzing energy conservation design.For different outer window's construction and material,the simulation method is used by DeST and Ecotect software in this issue,with analyzing and comparing energy conserved window material that is suitable to winter and summer.When there is outer blind sun shading system,for different orientation,different angles and different location of south outer window,Ecotect software is used to simulated and analyzed on energy conservation design on condition of seasons and times one day.The first chapter is about the overview of Shanghai's energy consumption,current outer window's material and energy consumption,the ways of sun shading,the application of soft wares.In the second chapter,different construction of the building model's outer window is simulated by DeST and Ecotect;furthermore,the building model energy consumption in winter and summer are considered simultaneously, concluded that the double insulating glass is suitable for outer window material.The third chapter is about a large area of south outer window with outer fixed level blind sun shading system,concluded that there is more sun shine through window into indoor when the blind angle between 30°and 60°in winter,and the level blind is meet to people's satisfaction in the premise of 300mm blind width.The forth chapter consider south window different location,that is in different tilt angle,concluded that 20°location not only can receive adequate sun radiation in winter,but also probably reduce sun shading system.The fifth chapter aims on west and north outer window with outer fixed vertical blind sun shading system,for west window—southern 60°revolved can receive adequate sun radiation in winter,and in summer one day the first place is northern 60°revolved,after 15:00 turns southern 60°;for north window—the blind in the location of perpendicular to the window or turn eastern less than or equal to 30°,the sun radiation after 15:00 is prevented.
