How has Park Haven's energy performance changed over time?

Its ENERGY STAR score went from 94 in 2023 to 85 in 2024 (-9 points); its best year on file was 2023, at 94. Site EUI moved from 31.8 kBtu/ft² (2023) to 38.1 kBtu/ft² (2024), an 20% increase. Reported emissions went from 632 tCO₂e to 801 tCO₂e over the same span (up 27%).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 falls in band A — high performer (85–100). 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. Park Haven's 38.1 kBtu/ft² across 185,630 sq ft works out to about 7.1 billion Btu (2,073 MWh-equivalent) in 2024. Its source EUI of 104.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,011,532 kWh of electricity and 2,016 therms of natural gas for the year.
