What does a site EUI of 33.2 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. 80-90 Winthrop st's 33.2 kBtu/ft² across 14,506 sq ft works out to about 0.5 billion Btu (141 MWh-equivalent) in 2024. Its source EUI of 92.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 139,711 kWh of electricity and 47 therms of natural gas for the year.
