Enter the fractional amount of solar energy that passes through a pane of glass into the calculator to determine the TSER.

## TSER Formula

The following equation is used to calculate the TSER.

TSER = (1-SHGC) *100
• Where TSER is the total solar energy rejected
• SHGC is the fractional amount of energy that has passed through a pane of glass

To calculate TSER, subtract the SHGC from 1, then multiply by 100.

The sum of the TSER and the SHFC should always equal 100%.

## What is TSER?

Definition:

TSER, short for total solar energy rejected, is a measure of the amount of solar energy that is rejected by a semi-translucent material, such as glass.

## How to Calculate TSER?

Example Problem:

The following example outlines the steps and information needed to calculate TSER.

First, determine the total fraction amount of solar energy that was able to pass through the material.

In this example, this is found to be .45 .

Next, the final and last last is to use the formula above to determine the total solar energy rejected

TSER = (1-SHGC) *100

TSER = (1-.45) *100

TSER = 55%
