What does an ENERGY STAR score of 30 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 30 means the building performs better than about 30% of its national peers. BuildingCensus bands the score into report-card grades; 30 falls in band D — lowest band (1–54). It sits 45 points below 75, the threshold for ENERGY STAR certification. In Evanston, 45% 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. 820 Church Street's 172.4 kBtu/ft² across 26,522 sq ft works out to about 4.6 billion Btu (1,340 MWh-equivalent) in 2019. Its source EUI of 286.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 470,372 kWh of electricity, 29,666 therms of natural gas and 208 thousand gallons of water for the year.
