What does a site EUI of 40.9 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. Convent HDFC's 40.9 kBtu/ft² across 29,000 sq ft works out to about 1.2 billion Btu (348 MWh-equivalent) in 2023. Its source EUI of 55.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 58,983 kWh of electricity and 9,859 therms of natural gas for the year.
