How has Taystee Life Science Building's energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for Taystee Life Science Building, covering report years 2023–2024. Site EUI moved from 10.1 kBtu/ft² (2023) to 25.8 kBtu/ft² (2024), an 155% increase. Reported emissions went from 214 tCO₂e to 657 tCO₂e over the same span (up 207%).
What does a site EUI of 25.8 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. Taystee Life Science Building's 25.8 kBtu/ft² across 260,965 sq ft works out to about 6.7 billion Btu (1,973 MWh-equivalent) in 2024. Its source EUI of 59.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,411,307 kWh of electricity and 19,301 therms of natural gas for the year.
Which law requires Taystee Life Science Building to report its energy use?
