How has 2 Seaman's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for 2 Seaman, covering report years 2022–2024. Its ENERGY STAR score went from 8 in 2022 to 11 in 2024 (+3 points).

What does an ENERGY STAR score of 11 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 11 means the building performs better than about 11% of its national peers. BuildingCensus bands the score into report-card grades; 11 falls in band D — lowest band (1–54). It sits 64 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. 2 Seaman's 158.0 kBtu/ft² across 59,200 sq ft works out to about 9.4 billion Btu (2,741 MWh-equivalent) in 2024. Its source EUI of 226.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 571,477 kWh of electricity and 70,062 therms of natural gas for the year.
