DE-79-05-1 -- Window Management: An Overview PDF

Window management has been defined as the selective alteration of the window's thermal and light transmission properties. In this paper the use of window management to alter window properties is discussed in terms of the need for energy conservation in buildings. Initially, a brief review of the psychological reaction to windows is given. Then thermal calculations of the energy balance at· the window are given in terms of the use of daylight and window management. Finally, several studies on actual window management practices are reviewed. These include the use of natural ventilation, natural light, and venetian blinds. In conclusion, the need for further research into the factors that affect the use of window management is suggested, along with the urgent requirement to evaluate the window as a total system.
