What does a site EUI of 49.1 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. Airport Way Ctr - Bldg C's 49.1 kBtu/ft² across 145,158 sq ft works out to about 7.1 billion Btu (2,089 MWh-equivalent) in 2025. Its source EUI of 128.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,863,076 kWh of electricity and 7,264 therms of natural gas for the year.
Which law requires Airport Way Ctr - Bldg C to report its energy use?
