What does a site EUI of 17.7 kBtu/ft² mean?
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 250 W Tasman Dr's 17.7 kBtu/ft² across 93,959 sq ft works out to about 1.7 billion Btu (487 MWh-equivalent) in 2024. Its source EUI of 49.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 486,803 kWh of electricity, 0 therms of natural gas and 34 thousand gallons of water for the year.
