What does a site EUI of 12.0 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. SWL349 - Bldg # 12's 12.0 kBtu/ft² across 226,488 sq ft works out to about 2.7 billion Btu (797 MWh-equivalent) in 2025. Its source EUI of 27.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 421,788 kWh of electricity and 5,563 therms of natural gas for the year.
Which law requires SWL349 - Bldg # 12 to report its energy use?
