Parameter ratio of solar tempered glass

What is total solar energy rejected (TSER)?

Total solar energy rejected (TSER): the fraction of solar energy not transmitted through a glass as heat. Light-to-solar-gain ratio (LSG ratio): the ratio of the visible light transmittance of a glass to its SHGC. Relative heat gain (RHG): the rate of heat gain through a glass under a summer daytime condition.

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.

How do you calculate solar energy fragmentation?

n the glass type. As this fragmentation accounts for 100% of the energy, the sum of the reflection, absorption and transmission is equ + T = 100% (or 1)Using 5mm grey glass as an example (see diagram on right), 5% of the solar energy is reflected, 48% is absorbed and 47% transmitt

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
