How does Gregorian Hotel compare with other hotel buildings in New York City?
The latest disclosures cover 970 hotel buildings in New York City, out of 48,310 buildings citywide. Gregorian Hotel's ENERGY STAR score of 68 compares with an average of 50 across the 853 that report a score; it scores higher than 70% of them and lower than 29%. Its site EUI of 45.6 kBtu/ft² is about half of the average of 94.3 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 38% below the group average of 7.8 kgCO₂e/ft².
At 55,948 sq ft, it is about 59% below the average floor area of 137,256 sq ft for those buildings. It was built in 1903, 72 years earlier than the group's average year built (1975). Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².
What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. Gregorian Hotel's 45.6 kBtu/ft² across 55,948 sq ft works out to about 2.6 billion Btu (748 MWh-equivalent) in 2024. Its source EUI of 116.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 643,181 kWh of electricity and 3,557 therms of natural gas for the year.
