How has Pless Hall's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Pless Hall, covering report years 2022–2024. Site EUI moved from 58.0 kBtu/ft² (2022) to 49.5 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 244 tCO₂e to 283 tCO₂e over the same span (up 16%).
What does a site EUI of 49.5 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. Pless Hall's 49.5 kBtu/ft² across 49,647 sq ft works out to about 2.5 billion Btu (720 MWh-equivalent) in 2024. Its source EUI of 138.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 719,609 kWh of electricity and 518 thousand gallons of water for the year.
