How has Double J Realty's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Double J Realty, covering report years 2022–2024. Its ENERGY STAR score was 99 in both 2022 and 2024. Site EUI moved from 3.5 kBtu/ft² (2022) to 2.9 kBtu/ft² (2024), a 17% decrease. Reported emissions went from 8 tCO₂e to 9 tCO₂e over the same span (up 12%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. Double J Realty's 2.9 kBtu/ft² across 25,658 sq ft works out to about 0.1 billion Btu (22 MWh-equivalent) in 2024. Its source EUI of 8.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 21,646 kWh of electricity and 46 thousand gallons of water for the year.
