A wide rangeof performance parameters can make selecting the right options diffi cult, and some parameters provide confl ictingperformance trade-offs. Good information about how to design green windows is not readily available, as most peoplelook through windows, but not many people look at them. Designed correctly, windows can greatly enhance the occupants’enjoyment of the space and enhance the energy performance of the entire building. Designed incorrectly,windows can be a source of irreparable failing of the building to meet the occupants’ requirements for comfort, energyeffi ciency, and long-term durability of the building envelope.This article discusses the physics behind window performance, describes some of the design parameters, and explainshow to determine whether you can get the performance you want on site. This is not meant to be an exhaustivereference on the subject, as that would require several books. Rather, the intent is to provide an overview of thephysical behavior of window components, so that appropriate design choices are based on sound knowledge and notguesswork. This article also provides some fl uency with window-performance terminology for use in discussing designoptions with specialists.展开更多
