Total Solar Energy Rejected (TSER) Calculator

TSER, or Total Solar Energy Rejected, is a crucial measure used to evaluate the effectiveness of materials like glass in rejecting solar energy. The TSER is calculated by subtracting the Solar Heat Gain Coefficient (SHGC), which is the fraction of solar energy passing through the material, from 1, and then multiplying the result by 100. This gives the percentage of solar energy that is rejected by the material.

TSER Formula

\[ \text{TSER} = (1 - \text{SHGC}) \times 100 \]

• SHGC: Fraction of solar energy passing through a material
• TSER: Percentage of solar energy rejected

Example Calculation

If the SHGC of a glass pane is 0.25, the TSER would be calculated as:

\[ \text{TSER} = (1 - 0.25) \times 100 = 75\% \]

This means 75% of the solar energy is rejected by the glass.

Importance and Usage Scenarios

TSER is an important metric in industries like construction and automotive design, where controlling the amount of solar energy that passes through glass is critical for energy efficiency and comfort.

Common FAQs

1. What does a higher TSER mean?

   • A higher TSER indicates better performance of the material in rejecting solar energy, leading to less heat penetration and better energy efficiency.

2. What is a typical SHGC value?

   • SHGC values typically range from 0 to 1, where 0 means no solar energy is transmitted, and 1 means all solar energy passes through the material.

3. How does TSER relate to energy savings?

   • Higher TSER values can contribute to energy savings by reducing the cooling load in buildings and vehicles, leading to lower air conditioning costs.

This TSER Calculator helps in quickly determining how much solar energy is being rejected by a material, which is essential for making informed decisions in design and material selection.
