Result Interpretation

Facilities Building Energy Use Intensity (EUI) Calculator computes Building Energy Use Intensity (EUI) in kWh/m² using the defined engineering formula and the input values provided. Building Energy Use Intensity (EUI) is expressed in kWh/m². No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Total Annual Energy Consumption = 420000
  • Conditioned Floor Area = 8400

Expected Result:

  • Building Energy Use Intensity (EUI) = 50

Engineering Interpretation:

Under the given input conditions, the calculated result is: Building Energy Use Intensity (EUI) = 50 kWh/m².

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
