What does an ENERGY STAR score of 35 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 35 means the building performs better than about 35% of its national peers. BuildingCensus bands the score into report-card grades; 35 falls in band D — lowest band (1–54). It sits 40 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. Hampden Green Condominium Association's 115.0 kBtu/ft² across 140,000 sq ft works out to about 16.1 billion Btu (4,718 MWh-equivalent) in 2023. Its source EUI of 155.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 824,706 kWh of electricity and 132,824 therms of natural gas for the year.

Which law requires Hampden Green Condominium Association to report its energy use?
