WebSolar heat gain coefficient. Andrey Solomon. Is the sum of the solar direct transmittance and the secondary heat transfer factor of the glazing towards the inside, the latter resulting from heat transfer by convection and longwave IR-radiation of that part of the incident solar radiation which has been absorbed by the glazing. WebThe solar heat gain coefficient (SHGC) and the solar factor (g-value) are used to measure the solar energy that transfers indoors. This includes direct transmission and indirect transmission because of absorption and inward re-radiation. The SHGC is the decimal share of the solar energy that is transmitted through a glazing composition.
Why is g-value so important? - m-sora-blog
WebIf the glazing area is doubled, the heat load increases with about 30%. Decreasing the glazed area to 50%, the heat load decreases with about 10%. The heat load decreases with about 3% if the g factor is lowered with 25% or the shading factor is reduced with 60%. Keywords: building; energy; heat load; sensitivity; glazing; surface cooling 1.
