A multitude of design strategies are available to achieve energy-efficient windows. Opportunities for improving window performance fall into six groups: site, exterior appendages, frame, glazing, interior accessories, and building interior. Design strategies within these groups can improve one or more of the six energy functions of windows: solar…

Public building air conditioning systems, which use constant and varying heat and cooling loads, are compared and investigated. Experiments indicated that constant temperature controls based on outside air temperature alone were inefficient. Ventilating a building with outside air and the methods of doing so are cited as being the most economical…

Solar heat gains (radiation) and its effects on the building environment are discussed, in conjunction with the proper and improper use of large glass areas in the exterior walls of buildings in North America. The difficulties of solar heat gain and of controlling natural light and glare are outlined and said to influence building comfort and air…
