How has MS Icahn Medical Institute's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for MS Icahn Medical Institute, covering report years 2022–2024. Site EUI moved from 152.1 kBtu/ft² (2022) to 81.6 kBtu/ft² (2024), a 46% decrease. Reported emissions went from 7,781 tCO₂e to 5,681 tCO₂e over the same span (down 27%).
What does a site EUI of 81.6 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. MS Icahn Medical Institute's 81.6 kBtu/ft² across 605,724 sq ft works out to about 49.4 billion Btu (14,486 MWh-equivalent) in 2024. Its source EUI of 227.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 14,432,810 kWh of electricity and 20 therms of natural gas for the year.
Which law requires MS Icahn Medical Institute to report its energy use?
