U Value Savings Calculator
Introduction & Importance
U-value, or thermal transmittance, is a measure of heat transfer through a building element. Understanding and optimizing your building’s U-value can lead to significant energy savings and cost reductions. Our U Value Savings Calculator helps you estimate these savings.
How to Use This Calculator
- Enter the U-value of your building element.
- Enter the area of the building element.
- Choose your preferred unit of measurement (BTU or kWh).
- Click ‘Calculate’ to see your estimated energy savings.
Formula & Methodology
The calculator uses the following formula to estimate energy savings:
Savings = (U-value * Area) / (Unit conversion factor)
The unit conversion factor is 1 for BTU and 3.412 for kWh.
