Its site EUI of 103.1 kBtu/ft² is roughly in line with the average of 94.3 kBtu/ft². Its emissions intensity of 7.6 kgCO₂e/ft² is roughly in line with the group average of 7.8 kgCO₂e/ft².

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 51 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 51 means the building performs better than about 51% of its national peers. BuildingCensus bands the score into report-card grades; 51 falls in band D — lowest band (1–54). It sits 24 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. NYCASA 46 Hotel's 103.1 kBtu/ft² across 27,250 sq ft works out to about 2.8 billion Btu (823 MWh-equivalent) in 2022. Its source EUI of 189.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 327,663 kWh of electricity for the year.
