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 Philadelphia, 35% 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. 8 Penn's 83.4 kBtu/ft² across 235,000 sq ft works out to about 19.6 billion Btu (5,744 MWh-equivalent) in 2020. Its source EUI of 169.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,971,257 kWh of electricity and 9,069 thousand gallons of water for the year.
