Is shgc better higher or lower
WitrynaIn the cooler northern climate zones, lower U-factor is more important, and higher SHGC can be justified. In selection of skylights, a balance is sought between low U-factor and optimal SHGC values, while … WitrynaIn cold winter months, a lower U-factor is especially important . It's worth noting that for some windows, like windows that face west and south, the contractor may recommend a higher or lower SHGC than in the rest of the house, because the amount of solar energy that reaches this window will be higher than in other parts of the house.

WitrynaLight to solar gain. Light-to-solar gain (LSG) is the ratio of the visible light transmittance to the Solar Heat Gain Coefficient (SHGC). LSG=Transmittance (Tvis)/SHGC. A higher LSG ratio means sunlight entering the room is more efficient for daylighting, especially for summer conditions where more light is desired with less solar gain. WitrynaA lower SHGC translates into less direct heat being pulled into the home resulting in lower cooling costs. SHGC and U-value are closely linked since the lowering of one directly affects the other. Lo-E refers to the ability of an IG unit to suppress direct heat radiation and absorb indirect heat radiation.
Witryna18 godz. temu · VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted. Air leakage* is expressed as the equivalent cubic feet of air passing through a square foot of window area (cfm/sq. ft).
