The heat transfer characteristics of a window system are generally specified by three static measurements; winter U-value, shading coefficient and air infiltration. Outlines methods for measuring these three values. Describes the mobile window test facility, designed to test windows under real weather conditions. The facility consists of a portable test building which can rotate about a central point.The building contains four test rooms with a guard room on each end.
