平均天空下计算的侧窗开窗量

Calculation of Lateral Windows Under Average Sky

在采暖地区通过窗损失的能量约为建筑能耗的50%,控制窗面积是寒冷地区普遍采取的一项有效的节能措施.本文从建筑采光角度出发,以平均天空概念为基础,提出了平均天空影响系数,修正了侧窗开窗量计算公式,分析了影响系数的建筑节能意义.

As the heat loss, through windows, occupies a half of the energy consumption in heat supplyiyd controlling window opening becomes a major approach in cold area. This paper, according to daylighting,based on an average sky, presents the influence coefficient of average sky, modifies the formula of calculating lateral windows and analysis the significance of energy saving in building by the influence coefficient.
