Key Glass Performance Measures
Visible light transmittance (VLT) is a percentage of the visible portion of the solar energy spectrum coming through the glass. It is expressed as a figure between 0 (no light) and

GLASS FOR FAÇADE
In complementarity to solar control glass in double or triple glazing, Low-E glass significantly reduce heat loss to the exterior, saving the energy need for internal heating.
Definitions of Key Terms
% Total Solar Energy Rejected (TSER): The percent of incident solar energy rejected by a glazing system. This value equals solar reflectance plus the part of solar absorption that is both re
PV Systems: Low Levels of Glare and Reflectance vs.
It should be noted from the graph and the table below, that the reflected energy percentage of Solar Glass is far below that of standard glass and more on the level of smooth water.

Performance value terms
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
Building Energy Performance Criteria Terms and References
The amount of visible light (390 to 770 nanometers within the solar spectrum) that passes through the glazing material of a window, expressed as a percentage of the total incident radiation in

Solar Glass – Sants Group
This refers to the percentage of solar radiation that passes through the glass. For standard solar glass, it''s often around 91% for a 3.2mm thickness. Anti-reflective coatings can increase this
Solar Factor: What It Is and How to Calculate It
The solar factor g of a glass surface, therefore, represents the percentage of thermal energy, τe, that directly passes through the pane compared to the total incident
