Technological advances in glazing and window assemblies, lighting, and energy management controls have complicated glazing systems design. Selecting a window assembly that provides the greatest value or efficiency is difficult considering the multitude of performance criteria that should be considered, the many available glazing options, and the profusion of window manufacturers in the marketplace. To address this problem, this report synthesizes up-to-date information on basic conservation strategies that relate to the design and specification of glazing and window assemblies. General concepts of building fenestration design and the role of the design professional in the selection of glazing systems are introduced. Information on heat transfer dynamics relating to glazed surfaces is presented and technological advances in glazing and window assemblies are discussed. Methods for the selection of glazing systems are also presented in the form of case studies, and a general discussion of window labeling and technical sources for information are presented. The report also provides design professionals, specifiers, and energy managers with references and sources for additional technical information on windows, glazing products, and issues surrounding new glazing technologies.
