Excerpt from Interim Procedure to Measure the Thermal Performance of Window Systems
In principle, the thermal performance of a fenestration can be predicted using heat transfer theory and correlations of experimental data involving convective and radiative heat flow, when the air space dimensions and radiative properties of the window are known and the adjacent air Space's temperature and flow field are specified [rubin, 1985; Siegel and Howell, The ashrae Handbook published by the Merican Society of Heating, Refrigerating and Air Conditioning Engineers [ashrae 1985, p. Provides thermal transmittance data for a number of widely used fenestrations based on a specific set of design conditions and recommends their use for determining peak energy loads in sizing heating and cooling equipment. However, because the specific design conditions are more severe than those to which the fenestration are exposed to on a continual basis, ashrae does not recommend the design data to be used for analysis of annual energy usage.

Paperback. Zustand: New. Print on Demand. This book synthesizes research on techniques for measuring thermal performance of windows. Its origins lie in a 1984 collaboration between the US Department of Energy and Bonneville Power Administration to develop a test procedure for rating movable window insulation. However, due to shifting priorities, the final work focused on developing a standard test procedure for measuring the thermal performance of windows in general. The book begins by reviewing current sources of window U -value data and describes common methods for measuring thermal performance of windows and movable insulation systems. It then examines the state of thermal test methods for windows at the time of writing and shares the results of site visits to different commercial and research laboratories to assess their thermal testing activities. Finally, the book outlines a research program for developing standardized window test methods, which would enable accurate comparison of performance claims by different manufacturers. The insights provided by this book have shaped the development of window test standards and continue to inform the field of window energy performance evaluation.
