What does a site EUI of 15.0 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. 37 BLUXOME ST's 15.0 kBtu/ft² across 63,280 sq ft works out to about 0.9 billion Btu (278 MWh-equivalent) in 2025. Its source EUI of 33.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 185,121 kWh of electricity and 3,152 therms of natural gas for the year.
Which law requires 37 BLUXOME ST to report its energy use?
