What does a site EUI of 79.5 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. 1455 Leary Building's 79.5 kBtu/ft² across 94,759 sq ft works out to about 7.5 billion Btu (2,208 MWh-equivalent) in 2025. Its source EUI of 205.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,497,539 kWh of electricity and 7,214 therms of natural gas for the year.
Which law requires 1455 Leary Building to report its energy use?
