Technical FAQs 4
What data are used to calculate solar energy performance?
re less damaging.The performance data detailed in this guide include Centre of Glass (COG), U-Value, Solar Heat Gain Coeficient (SHGC) and Shading Coeficient (SC), all of which are calculated using the Lawrence Berkeley National Laboratory (LBNL) Window
What is a solar heat gain coefficient?
The lower a window’s solar heat gain coefficient, the less solar heat it transmits. Zero represents an impenetrable wall against solar heat and.1 represents direct exposure to the sun’s heat. For example, a glass with a SHGC of 0.27 allows 27% of the sun’s solar heat to pass through, meaning it blocks 73%.
What is solar energy absorbed by glass?
Solar Energy Absorptance (Ae, %) is the percentage of the sun's energy that is absorbed by glass. Solar Factor or Total Solar Energy Transmittance or g-value (g%) is the total solar radiation transmitted by the glass. Shading Coefficient (sc) is Solar Factor divided by 0.87.
What is the difference between Solar Factor and shading coefficient?
Solar Factor or Total Solar Energy Transmittance or g-value (g%) is the total solar radiation transmitted by the glass. Shading Coefficient (sc) is Solar Factor divided by 0.87. It is a measure of the solar heat gain referenced to 3 mm clear glass which has the designated value of 1.00.
