Its ENERGY STAR score went from 100 in 2022 to 9 in 2024 (-91 points); its best year on file was 2022, at 100. Site EUI moved from 0.3 kBtu/ft² (2022) to 136.9 kBtu/ft² (2024), an 45533% increase. Reported emissions went from 18 tCO₂e to 10,008 tCO₂e over the same span (up 56442%).

What does an ENERGY STAR score of 9 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 9 means the building performs better than about 9% of its national peers. BuildingCensus bands the score into report-card grades; 9 falls in band D — lowest band (1–54). It sits 66 points below 75, the threshold for ENERGY STAR certification. 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. SUMNER's 136.9 kBtu/ft² across 1,045,000 sq ft works out to about 143.1 billion Btu (41,927 MWh-equivalent) in 2024. Its source EUI of 188.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,070,299 kWh of electricity and 822,078 therms of natural gas for the year.

Which law requires SUMNER to report its energy use?
