How has The Brook's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for The Brook, covering report years 2022–2024. Its ENERGY STAR score went from 50 in 2022 to 76 in 2024 (+26 points). Site EUI moved from 89.0 kBtu/ft² (2022) to 70.8 kBtu/ft² (2024), a 20% decrease. Reported emissions went from 615 tCO₂e to 545 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. The Brook's 70.8 kBtu/ft² across 90,885 sq ft works out to about 6.4 billion Btu (1,886 MWh-equivalent) in 2024. Its source EUI of 137.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 957,845 kWh of electricity, 31,705 therms of natural gas and 8,297 thousand gallons of water for the year.
