How has Galileo 301/303/303A Campus's energy performance changed over time?

BuildingCensus holds 2 New York City disclosures for Galileo 301/303/303A Campus, covering report years 2022–2023. Its ENERGY STAR score went from 48 in 2022 to 83 in 2023 (+35 points). Site EUI moved from 78.4 kBtu/ft² (2022) to 48.3 kBtu/ft² (2023), a 38% decrease. Reported emissions went from 515 tCO₂e to 395 tCO₂e over the same span (down 23%).

What does an ENERGY STAR score of 83 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In New York City, 43% of scored buildings are at 75 or above.

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. Galileo 301/303/303A Campus's 48.3 kBtu/ft² across 105,046 sq ft works out to about 5.1 billion Btu (1,487 MWh-equivalent) in 2023. Its source EUI of 88.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 658,378 kWh of electricity, 28,302 therms of natural gas and 4,319 thousand gallons of water for the year.
