Its ENERGY STAR score went from 99 in 2022 to 80 in 2024 (-19 points); its best year on file was 2022, at 99. Site EUI moved from 37.8 kBtu/ft² (2022) to 64.8 kBtu/ft² (2024), an 71% increase. Reported emissions went from 166 tCO₂e to 293 tCO₂e over the same span (up 77%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. 217 LLC's 64.8 kBtu/ft² across 70,000 sq ft works out to about 4.5 billion Btu (1,329 MWh-equivalent) in 2024. Its source EUI of 89.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 246,396 kWh of electricity and 36,939 therms of natural gas for the year.
