What does a site EUI of 39.8 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. 1066 Cambridge Street's 39.8 kBtu/ft² across 26,142 sq ft works out to about 1 billion Btu (305 MWh-equivalent) in 2024. Its source EUI of 70.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 125,997 kWh of electricity, 6,110 therms of natural gas and 860 thousand gallons of water for the year.

Which law requires 1066 Cambridge Street to report its energy use?
