SHGC/g-value – Total solar energy entering into the building. Value between 0 and 1. The lower the g-value, the more efficient the glazing is in blocking solar entry.
LSG: Light to Solar – Gain (selectivity) Ratio between the visible light transmittance (VLT) and the Solar Heat Gain Coefficient (SHGC). The higher the LSG, the better the glazing is in reducing more solar energy than visible light.
U-value -Thermal Transfer Coefficient. Quantity of heat transmitted through the glazing due to the temperature difference between inside and outside. The lower the U-value, the better the thermal insulation performance.
Shading Coefficient – (SC) SC = SHGC/0.87
