How does Lexington-RDA 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. Lexington-RDA's ENERGY STAR score of 26 compares with an average of 50 across the 853 that report a score; it scores higher than 25% of them and lower than 74%. Its site EUI of 88.0 kBtu/ft² is roughly in line with 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 7.7 kgCO₂e/ft² is roughly in line with the group average of 7.8 kgCO₂e/ft².
At 324,381 sq ft, it is about 136% above the average floor area of 137,256 sq ft for those buildings. It was built in 1929, 46 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 26 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 26 means the building performs better than about 26% of its national peers. BuildingCensus bands the score into report-card grades; 26 falls in band D — lowest band (1–54). It sits 49 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. Lexington-RDA's 88.0 kBtu/ft² across 324,381 sq ft works out to about 28.5 billion Btu (8,366 MWh-equivalent) in 2024. Its source EUI of 166.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,608,934 kWh of electricity, 1,604 therms of natural gas and 22,516 thousand gallons of water for the year.
