BuildingCensus holds 3 New York City disclosures for The Morgan Library and Museum, covering report years 2022–2024. Site EUI moved from 149.1 kBtu/ft² (2022) to 150.8 kBtu/ft² (2024), an 1% increase. Reported emissions went from 2,080 tCO₂e to 2,495 tCO₂e over the same span (up 20%).
What does a site EUI of 150.8 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. The Morgan Library and Museum's 150.8 kBtu/ft² across 186,440 sq ft works out to about 28.1 billion Btu (8,240 MWh-equivalent) in 2024. Its source EUI of 292.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,805,783 kWh of electricity, 2,728 therms of natural gas and 4,921 thousand gallons of water for the year.
