Urban Earth Building Performance Tool

Building MPG Calculator

Turn utility data into a clear energy performance score for buyers, sellers, and realtors. The calculator reports measured EUI first, then gives house-vintage context.

Measured Energy Use Intensity 0.0 kBtu per square foot per year

Copy-ready listing language

Electricity

Annual kWh × 3.412 = annual kBtu.

Natural gas

Annual therms × 100 = annual kBtu.

EUI

Total annual kBtu ÷ square feet = kBtu/sf/year.

These vintage benchmarks are starter assumptions for screening and education. Replace them with documented ENERGY STAR, EIA, local utility, code-era, or project-specific benchmark data before using the calculator for formal claims.
