Principles of design of architectural coatings

A survey is presented of the essential design considerations involved in the development of architectural thin film coatings. The report is divided into two parts: the first deals with design factors that influence the thermal performance of windows; the second deals with questions of aesthetics, especially color. A brief discussion is included of heat transfer analysis as it applies to glazings, along with an attachment of some sample graphs of heat transfer properties and their relationship to the optical properties of coated glass. Also included is an overview, with computed examples, of the various coating design types that appear to be viable at the current stage of development in this field of thin films technology.
