Work out energy use intensity instantly with clear inputs, formula shown and shareable results.
Energy use intensity normalises consumption by floor area so buildings of different size can be compared. Reporting conventions differ: Europe and Asia use kilowatt hours per square metre a year, North America uses thousand Btu per square foot. A well managed office sits around 100-150 kWh/m², a poor one above 250.
Energy use intensity
kWh/m²/year = annual kWh / area in m²; kBtu/ft² = kWh/ft² x 3.412
kWh/m²/year = annual kWh / area in m²; kBtu/ft² = kWh/ft² x 3.412. Energy use intensity normalises consumption by floor area so buildings of different size can be compared.
Yes for a complete picture. Site EUI adds all delivered energy in common units, and source EUI further accounts for generation and transmission losses, which roughly triples the electricity component.
This calculator takes 2 inputs: Annual electricity consumption, Gross floor area. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
