这扇窗户一直是能源研究人员特别关注的一个问题，因为它可能会产生巨大的热量增益和损失。因此，许多设计师探索了控制或管理窗户能量相关特性的方法，同时保留了窗户的热、光和心理效益。建议改善窗户性能的技术包括:（1）使用合适尺寸的窗户，（2）吸收或反射能量的窗户涂层，以及（3）内部和外部遮阳装置。结合马里兰州盖瑟斯堡国家标准局（NBS）的能源使用监测研究项目，对内部遮阳设备的使用进行了研究。尽管许多关于建筑节能的建议要求居住者积极参与这一过程，但关于目前的参与程度或参与类型的信息很少，即使是关于窗户遮阳设备的使用或管理这样简单的问题。 引文:宾夕法尼亚州费城ASHRAE学报第85卷第1部分研讨会

The window has been a source of particular concern to energy researchers because of its potential for large heat gains and losses. As a result, many designers have explored ways of controlling or managing energy-related characteristics of windows, while preserving their thermal, lighting and psychological benefits. Among the techniques suggested for improving window performance are the use of: (1) appropriate sizes for windows, (2) window coatings to absorb or reflect energy, and (3) shading devices, both internal and external.In conjunction with a research program monitoring energy use at the National Bureau of Standards (NBS) in Gaithersburg, Maryland, a study of the use of internal shading devices was undertaken.Although many suggestions for energy conservation in buildings require the occupant to participate actively in the process, little information is available on the degree or kind of participation currently practiced, even on a matter as simple as the use or management of shading devices at the window.
