What does a site EUI of 41.2 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. 387 Western Ave's 41.2 kBtu/ft² across 11,491 sq ft works out to about 0.5 billion Btu (139 MWh-equivalent) in 2024. Its source EUI of 71.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 53,547 kWh of electricity, 2,904 therms of natural gas and 236 thousand gallons of water for the year.
Which law requires 387 Western Ave to report its energy use?
