What does an ENERGY STAR score of 17 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 17 means the building performs better than about 17% of its national peers. BuildingCensus bands the score into report-card grades; 17 falls in band D — lowest band (1–54). It sits 58 points below 75, the threshold for ENERGY STAR certification. In Washington, DC, 47% 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. Fannie Mae 3939; SSL: 1825 0002:1825 0800's 112.8 kBtu/ft² across 44,819 sq ft works out to about 5.1 billion Btu (1,482 MWh-equivalent) in 2015. Its source EUI of 312.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,217,817 kWh of electricity, 9,023 therms of natural gas and 1,612 thousand gallons of water for the year.
