What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. 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. Wallingford Retail And Office Building's 47.4 kBtu/ft² across 31,774 sq ft works out to about 1.5 billion Btu (441 MWh-equivalent) in 2025. Its source EUI of 126.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 432,316 kWh of electricity and 1,286 therms of natural gas for the year.
Which law requires Wallingford Retail And Office Building to report its energy use?
