Enter the total solar gain and the incident solar radiation into the Calculator. The calculator will evaluate the Glass G Value.

## Glass G Value Formula

G-V = SG+ ISR

Variables:

- G-V is the Glass G Value ()
- SG is the total solar gain
- ISR is the incident solar radiation

To calculate Glass G Value, simply sum the total solar gain and the incident solar radiation together.

## How to Calculate Glass G Value?

The following steps outline how to calculate the Glass G Value.

- First, determine the total solar gain.
- Next, determine the incident solar radiation.
- Next, gather the formula from above = G-V = SG+ ISR.
- Finally, calculate the Glass G Value.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total solar gain = 47

incident solar radiation = 89
