What does a site EUI of 55.9 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. 503, 503 Main St.'s 55.9 kBtu/ft² across 39,400 sq ft works out to about 2.2 billion Btu (645 MWh-equivalent) in 2019. Its source EUI of 97.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 257,435 kWh of electricity, 13,246 therms of natural gas and 1,990 thousand gallons of water for the year.
