Applied Science Division Annual Report, FY 1987: Windows and Lighting Program
Over 30% of all energy used in buildings is attributable to two building elements, windows and lighting. Together they account for annual consumer expenditures of over $50 billion. Each affects not only energy use by other major building systems but also comfort and productivity, factors that have a far greater influence on building economics than direct energy consumption alone. Windows play a unique role in the building envelope, physically separating the conditioned space from the world outside without sacrificing vital visual contact. Lighting systems make it possible to conduct any task of any visual difficulty anywhere in the indoor environment, and at the same time define the luminous qualities of the indoor environment. The two building elements are thus essential components to any comprehensive building science program. The Windows and Daylighting Group focuses on developing the technical basis for understanding the energy-related performance of windows. If the flow of heat and light through windows and skylights can be properly filtered and controlled, these building elements can outperform any insulated wall or roof component and provide net energy benefits to the building. The group's investigations are designed to develop the capability to accurately predict net fenestration performance in residential and commercial buildings. 38 refs., 25 figs. (ERA citation 14:022370)
