6 FAQs about Solar Glass solar ratio

What is light to solar gain ratio (LSG)?

Light to Solar Gain Ratio (LSG) is a measure used to evaluate the energy efficiency of window glass. It compares the amount of visible light that a window allows to pass through (Visible Light Transmittance or VLT) to the amount of solar heat gain that the window allows to pass through (Solar Heat Gain Coefficient or SHGC).

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 are the factors affecting the choice of glass?

The main values in the choice of glass are thermal transmittance, light transmittance, and the solar factor. The solar factor g is the ratio between the solar energy that manages to pass through the glass entering the environment and the total solar energy that strikes the outer surface of the glazing.

How much light does a glass block?

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%. Light to Solar Gain (LSG) is a ratio that results from a window’s SHGC being divided by its VLT rating. The LSG ratio measures the glass's ability to transmit light and block heat in the form of infrared energy.

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 data are used to calculate solar energy performance?
