Performance GUIDE

Selecting glass for a project is an important and sometimes dificult task, to assist in this process G.James ofers the following recommendation for viewing glass samples.

Measurement of Solar Transmittance through Plate Glass

In this example, several types of glass were measured using a UV-3600 UV-VIS-NIR spectrophotometer and their solar transmittance was calculated using solar transmittance

Understanding Glass Performance Key Metrics

For example, a glass with an SHGC of 0.33 allows only 33% of solar heat to pass through, keeping interiors cooler and reducing cooling costs. LSG is

Light to solar gain: lsg ratio definition | Guardian Glass

LSG=Transmittance (Tvis)/SHGC. A higher LSG ratio means sunlight entering the room is more efficient for daylighting, especially for summer

Energy Performance Ratings for Windows, Doors, and Skylights

It provides a gauge of the relative efficiency of different glass or glazing types in transmitting daylight while blocking heat gains. The higher the number, the more light transmitted without

Light to solar gain: lsg ratio definition | Guardian Glass

LSG=Transmittance (Tvis)/SHGC. A higher LSG ratio means sunlight entering the room is more efficient for daylighting, especially for summer conditions where more light is desired with less

Building Energy Performance Criteria Terms and References

Light-to-Solar Gain Ratio (LSG) The visible transmittance of a glazing divided by its solar heat gain coefficient.

Factors in Window Selection, page 2 | EGEE 102: Energy

The light-to-solar gain ratio (LSGR) provides a gauge of the relative efficiency of different glass types in transmitting daylight while blocking heat gains. It is determined by the ratio between

Light to Solar Gain Ratio (LSG) | Cardinal Glass Industries

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

Understanding Glass Performance Key Metrics

For example, a glass with an SHGC of 0.33 allows only 33% of solar heat to pass through, keeping interiors cooler and reducing cooling costs. LSG is the ratio of a window''s SHGC to its

Key Glass Performance Measures

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
