What does an ENERGY STAR score of 19 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 19 means the building performs better than about 19% of its national peers. BuildingCensus bands the score into report-card grades; 19 falls in band D — lowest band (1–54). It sits 56 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 3900 (222231) SSL: 1823 0801's 122.3 kBtu/ft² across 245,397 sq ft works out to about 30 billion Btu (8,796 MWh-equivalent) in 2016. Its source EUI of 275.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,053,723 kWh of electricity, 93,578 therms of natural gas and 8,831 thousand gallons of water for the year.
