What does an ENERGY STAR score of 52 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 52 means the building performs better than about 52% of its national peers. BuildingCensus bands the score into report-card grades; 52 falls in band D — lowest band (1–54). It sits 23 points below 75, the threshold for ENERGY STAR certification. In Chicago, 35% 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. The Narragansett Condominium Inc's 81.4 kBtu/ft² across 147,000 sq ft works out to about 12 billion Btu (3,507 MWh-equivalent) in 2023. Its source EUI of 98.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 326,189 kWh of electricity and 108,489 therms of natural gas for the year.
