How has Rose House's energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for Rose House, covering report years 2022–2023. Its ENERGY STAR score went from 98 in 2022 to 99 in 2023 (+1 points).

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. Rose House's 63.7 kBtu/ft² across 33,791 sq ft works out to about 2.2 billion Btu (631 MWh-equivalent) in 2023. Its source EUI of 105.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 216,830 kWh of electricity, 14,142 therms of natural gas and 1,048 thousand gallons of water for the year.
