What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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 Seattle, 69% 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. Modera Broadway Apartments's 35.8 kBtu/ft² across 150,335 sq ft works out to about 5.4 billion Btu (1,577 MWh-equivalent) in 2025. Its source EUI of 75.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 799,584 kWh of electricity and 16,285 therms of natural gas for the year.
