遮阳应被视为商业和办公建筑的开窗系统设计的一个组成部分，以平衡采光要求和减少太阳能增益的需要。在本文中，玻璃面积，遮阳设备的性能和遮阳控制对建筑物的冷却和照明需求的同时影响进行了计算，使用耦合的照明和热模拟模块。周边空间的冷却和照明能源使用之间的相互作用进行了评估，作为一个功能的窗墙比和遮阳参数。外部卷帘被用作示例。定量分析了遮阳设备类型、性能和控制对建筑降温和照明能耗的影响。模拟结果表明，如果一个综合的方法，自动控制电动遮阳与可控的电力照明系统，大幅度减少冷却和照明的能源需求，可以实现在周边空间，这取决于气候条件和方向。
Shading should be considered as an integral part of fenestration system design for commercial and office buildings, in order to balance daylighting requirements versus the need to reduce solar gains. In this paper, the simultaneous impact of glazing area, shading device properties and shading control on building cooling and lighting demand was calculated using a coupled lighting and thermal simulation module. The interactions between cooling and lighting energy use in perimeter spaces were evaluated as a function of window-to-wall ratio and shading parameters. An exterior roller shade was used as an example. The impact of shading device type, properties and control on building cooling and lighting energy demand was quantified and analyzed. The simulation results indicate that, if an integrated approach for automatic control of motorized shading is used in conjunction with controllable electric lighting systems, substantial reduction of energy demand for cooling and lighting could be achieved in perimeter spaces, depending on climatic conditions and orientation.
