What does a site EUI of 27.6 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. 50 Fremont Center's 27.6 kBtu/ft² across 955,092 sq ft works out to about 26.4 billion Btu (7,726 MWh-equivalent) in 2025. Its source EUI of 66.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,496,543 kWh of electricity and 55,903 therms of natural gas for the year.
