When selecting a window, the Solar Heat Gain Coefficient (SHGC) primarily describes what performance property?
a.How much solar heat the window admits into the interior
b.How much air leaks around the sash
c.The window's resistance to forced entry
d.How much the glass reduces exterior noise
Explanation
SHGC measures the fraction of solar radiation admitted through the window; a lower SHGC reduces unwanted summer heat gain and cooling loads. Air leakage is rated separately, and neither forced-entry resistance nor sound transmission is what SHGC measures.
