EUI Calculator: Energy Use Intensity for Buildings

Your details

Choose whether to enter floor area in square feet (imperial) or square metres (metric).
Used to compare your EUI against the national median for similar buildings (CBECS 2018 data).
The gross conditioned (heated/cooled) area of the building.
ft²
Total electricity consumed in the past 12 months, from utility bills.
kWh
Total natural gas consumed in therms (1 therm = 100 kBtu). Check your gas utility bills.
therms
Annual consumption of No. 2 distillate fuel oil (heating oil). Leave at 0 if not used.
gallons
Annual propane consumption in gallons. Leave at 0 if not used.

EUI of 59.2 - there is room to improve vs. the Office (Small) benchmark.

  • Your EUI of 59.2 kBtu/ft²/yr is 23% below the national median of 77 for Office (Small) buildings - a strong result.
  • Reaching the efficient threshold of 45 kBtu/ft²/yr would save roughly 142 MMBtu/yr (equivalent to about 41559 kWh).
  • Estimated CO2 emissions are 33,003 kg/yr. Reducing EUI by 10% would cut roughly 3300 kg CO2/yr.
  • Electricity dominates your energy mix. Demand-side measures such as LED lighting, variable-speed drives, and efficient HVAC typically yield the highest savings in electricity-heavy buildings.

Next stepAn energy audit (ASHRAE Level 1 or 2) will identify the highest-impact improvement measures specific to your building.
