South Portland Residences's ENERGY STAR score of 100 compares with an average of 63 across the 22,829 that report a score; it scores higher than 90% of them. Its site EUI of 31.8 kBtu/ft² is about 58% below the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.6 kgCO₂e/ft² is about half of the group average of 5.2 kgCO₂e/ft².
At 105,687 sq ft, it is roughly in line with the average floor area of 100,951 sq ft for those buildings. It was built in 2022, 70 years later than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). 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. South Portland Residences's 31.8 kBtu/ft² across 105,687 sq ft works out to about 3.4 billion Btu (985 MWh-equivalent) in 2024. Its source EUI of 59.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 462,922 kWh of electricity, 17,830 therms of natural gas and 1,154 thousand gallons of water for the year.
