The formula to calculate the Glass G Value is:
\[ G-V = SG + ISR \]
Where:
The Glass G Value is a measure of the total solar energy transmittance of a glazing system. It is calculated by summing the total solar gain and the incident solar radiation. This value is important for understanding the thermal performance of glass in buildings, as it affects the amount of heat that passes through the glass and impacts the building's energy efficiency.
Let's assume the following values:
Using the formula:
\[ G-V = 200 + 300 = 500 \]
The Glass G Value (G-V) is 500.
