What does a site EUI of 26.5 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. Harbor Crest Condominium's 26.5 kBtu/ft² across 26,827 sq ft works out to about 0.7 billion Btu (208 MWh-equivalent) in 2025. Its source EUI of 74.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 173,311 kWh of electricity for the year.
Which law requires Harbor Crest Condominium to report its energy use?
