Work Item

ASTM WK80979

New Test Method for Measuring the Solar Heat Gain Coefficient of Fenestration Systems Using Calorimetry Hot Box Methods

1. Scope

This test method provides requirements and guidelines and specifies calibration procedures required for the measurement of the Solar Heat Gain Coefficient (SHGC) of fenestration systems and glazing systems installed in a solar calorimeter (hot box). C. This test method specifies the necessary measurements to be made using solar calorimeters exposed to solar radiation under clear sky conditions (outdoors) or using artificial solar simulators (indoors).

Keywords

SHGC, Solar Heat Gain, Solar Simulator, Calorimeter, Solar Calorimeter

Rationale

This standard is needed to provide a uniform and accurate test method to testing fenestration products for solar heat gain with either the sun as the source or artificial sun via solar simulators.
