How does 50 Hudson Yards compare with other office buildings in New York City?
The latest disclosures cover 3,384 office buildings in New York City, out of 48,310 buildings citywide. 50 Hudson Yards's ENERGY STAR score of 76 compares with an average of 72 across the 2,519 that report a score; it scores higher than 44% of them and lower than 54%. Its site EUI of 51.8 kBtu/ft² is about 20% below the average of 64.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.8 kgCO₂e/ft² is about 17% below the group average of 5.8 kgCO₂e/ft².
At 2,944,455 sq ft, it is about 1333% above the average floor area of 205,440 sq ft for those buildings. It was built in 2022, 82 years later than the group's average year built (1940). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. 50 Hudson Yards's 51.8 kBtu/ft² across 2,944,455 sq ft works out to about 152.5 billion Btu (44,700 MWh-equivalent) in 2023. Its source EUI of 120.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 32,464,639 kWh of electricity, 415,818 therms of natural gas and 25,225 thousand gallons of water for the year.
