When direct solar beam falls on a sheet of glass, a part of solar energy is transmitted through glass into the building interior, a part is reflected, and a part is absorbed by the glass. For a clear glass sheet, the percentage of transmitted energy is 85%, reflected energy is 10% and the remaining 5% is absorbed by glass. What is your estimate of the percentage solar heat gain (SHG)of this glass, defined as the percentage of solar energy that enters the building interior? Explain.
