What does a site EUI of 38.1 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. Interland - 1355 Sansome's 38.1 kBtu/ft² across 67,930 sq ft works out to about 2.6 billion Btu (759 MWh-equivalent) in 2025. Its source EUI of 86.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 528,428 kWh of electricity and 7,884 therms of natural gas for the year.
