Energy Use Intensity (EUI) Calculator
Result
Energy Use Intensity (EUI) Calculator The Energy Use Intensity Calculator divides a building's annual energy use by its floor area to give the EUI, a standard benchmark of building energy efficiency. Enter annual energy and floor area. — free online calculator.
Formula
- Energy Use Intensity (EUI) Calculator calculates its result from Annual Energy Use, Floor Area. It uses the formula EUI = Annual Energy Use ÷ Floor Area. Change any input to recalculate the result instantly.
- The main inputs are Annual Energy Use, Floor Area. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Energy Use Intensity (EUI)
- Annual Energy Use: 120000
- Floor Area: 1000
Using Annual Energy Use = 120000, Floor Area = 1000, the calculated result is 120.
