Sustainability · Defined
Site energy
Energy consumed at a property as measured at its delivery boundary, commonly using utility bills and on-site fuel records.
Why it matters
Use a consistent area, time period, and fuel-conversion basis when comparing buildings. Site energy differs from source energy, which accounts for upstream energy use.
In practice
A project example
Electricity and gas consumption are converted to common units before calculating the property’s site EUI.
