Description

This paper describes measurements made at a Solar Calorimetry Laboratory of solar heat gain coefficient and U-factor of a window and shade combination at 45º and 90º tilt angles. The test sample was one sheet of 6.4 mm (1/4 in.) double-strength clear glass and a shade consisting of aluminum foil painted flat black on both sides and mounted on the interior of the window. The test requirements were specified in a document entitled Test of Measured Solar Heat Gain Variation with Respect to Test Specimen Tilt, prepared by the NFRC Solar Heat Gain Test Procedure Task Group. Results indicate that there was a 5% decrease in the measured solar heat gain coefficient and a 22% increase in the system U-factor between vertical and 45º tilt angles.
