How has Alexandria Center for Life Science's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Alexandria Center for Life Science, covering report years 2022–2024. Site EUI moved from 206.2 kBtu/ft² (2022) to 257.8 kBtu/ft² (2024), an 25% increase. Reported emissions went from 13,202 tCO₂e to 17,105 tCO₂e over the same span (up 30%).
What does a site EUI of 257.8 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. Alexandria Center for Life Science's 257.8 kBtu/ft² across 795,486 sq ft works out to about 205.1 billion Btu (60,102 MWh-equivalent) in 2024. Its source EUI of 537.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 29,747,713 kWh of electricity and 13,233 therms of natural gas for the year.
Which law requires Alexandria Center for Life Science to report its energy use?
Alexandria Center for Life Science reports under Local Law 84 (LL84), the legal basis of New York City's Energy and Water Data Disclosure program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record nyc:6768271:2024).
