Finish TradesCâu 416 / 700
Under the California Energy Code, a lower fenestration U-factor for windows indicates what about the window's performance?
a.Greater visible light transmittance
b.Higher air leakage
c.Better resistance to conductive heat transfer (less heat loss)
d.A larger glazing area
Giải thích
U-factor measures the rate of conductive heat transfer, so a lower U-factor means the window loses less heat and performs better thermally. It is not a direct measure of visible light transmittance, air leakage, or glazing area, which are tracked by separate ratings such as VT and SHGC.
