What does a site EUI of 23.3 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. Breakwater's 23.3 kBtu/ft² across 100,000 sq ft works out to about 2.3 billion Btu (683 MWh-equivalent) in 2023. The disclosure also reports 52,262 kWh of electricity and 22,545 therms of natural gas for the year.
