What does a site EUI of 35.0 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. 33 New Montgomery's 35.0 kBtu/ft² across 244,804 sq ft works out to about 8.6 billion Btu (2,511 MWh-equivalent) in 2025. Its source EUI of 78.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,717,500 kWh of electricity and 27,169 therms of natural gas for the year.
