What does a site EUI of 272.0 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. Carlsbad W4's 272.0 kBtu/ft² across 60,000 sq ft works out to about 16.3 billion Btu (4,783 MWh-equivalent) in 2019. The disclosure also reports 4,353,706 kWh of electricity and 15,558 therms of natural gas for the year.
