Its site EUI of 47.3 kBtu/ft² is about 37% below the average of 75.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.2 kgCO₂e/ft² is about half of the group average of 6.5 kgCO₂e/ft².
At 27,100 sq ft, it is about 67% below the average floor area of 81,524 sq ft for those buildings. It was built in 1921, 41 years earlier than the group's average year built (1963). Across all 24 jurisdictions BuildingCensus covers, the 3,025 retail store buildings average an ENERGY STAR score of 73 and a site EUI of 57.7 kBtu/ft².
What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 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. 34 Westchester Square's 47.3 kBtu/ft² across 27,100 sq ft works out to about 1.3 billion Btu (376 MWh-equivalent) in 2022. Its source EUI of 88.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 174,418 kWh of electricity for the year.
