What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 points below 75, the threshold for ENERGY STAR certification. In Portland, 66% 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. Northrup Center's 57.0 kBtu/ft² across 22,135 sq ft works out to about 1.3 billion Btu (370 MWh-equivalent) in 2024. The disclosure also reports 225,262 kWh of electricity and 4,929 therms of natural gas for the year.
