Kessel, J; Selkowitz, S

Equations are presented that express the directional-hemispherical transmittance of window systems in terms of the experimental parameters of an integrating sphere. The construction and operation of a 2-meter-diameter sphere is described. Experimental results are given for both conventional and novel window systems.
