How has Silks Building's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Silks Building, covering report years 2022–2024. Its ENERGY STAR score went from 88 in 2022 to 87 in 2024 (-1 points); its best year on file was 2023, at 89. Site EUI moved from 67.1 kBtu/ft² (2022) to 63.9 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 539 tCO₂e to 478 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Silks Building's 63.9 kBtu/ft² across 114,009 sq ft works out to about 7.3 billion Btu (2,135 MWh-equivalent) in 2024. Its source EUI of 89.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 428,884 kWh of electricity, 58,271 therms of natural gas and 299 thousand gallons of water for the year.
