Calculate Heat Loss per Square Meter
Introduction & Importance
Calculating the rate of heat loss per square meter is crucial for energy efficiency and comfort in buildings. It helps determine the required heating power and identify areas of heat loss…
How to Use This Calculator
- Enter the area in square meters.
- Enter the U-value in W/m²K.
- Enter the temperature difference in °C.
- Click ‘Calculate’.
Formula & Methodology
The formula for heat loss per square meter is:
Q = U * A * ΔT
Where:
- Q is the heat loss (W),
- A is the area (m²),
- U is the U-value (W/m²K),
- ΔT is the temperature difference (°C).
For more information, see the U.S. Department of Energy’s energy glossary.

What is a U-value?
The U-value, or overall heat transfer coefficient, is a measure of heat transfer rate through a building element (like a wall or roof) due to a unit temperature difference between the environments on either side.
