The Research Of Daylighting And Energy Consumption On Office Building

At present,China's energy situation is extremely serious,the question of building energy consumption is extremely serious , Public building energy consumption is extremely huge of total building energy consumption.Office buildings are the main research objects in this article because its characteristic tokens that of other public buildings to a large extent.With the comparison of lighting,daylighting can save energy and diminish the peak value of building energy consumption. Daylighting can make people in a good humor and improve work efficiency. Solar energy is exhaustless renewable energy. At present, for many reasons special daylighting designs don't be included in a great deal of architecture designs in our country,which debases indoor comfort and increases lighting energy consumption.And if daylight is taken good use for lighting in daylight,large amount of lighting energy consumption will be saved.Most domestic studies on daylighting are only limited to qualitative analysis with the consideration of aestietics effect,and no detailed and systematical quantitative study on daylight utilization with the combination of daylighting and building energy consumption.Through a compendious sky model,numerical simulation is used to analyze the key factors affecting daylighting such as window-to-floor ratio,window figuration,transmittance and window position.
