What does an ENERGY STAR score of 48 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 48 means the building performs better than about 48% of its national peers. BuildingCensus bands the score into report-card grades; 48 falls in band D — lowest band (1–54). It sits 27 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. 1635 Market's 77.7 kBtu/ft² across 318,307 sq ft works out to about 24.7 billion Btu (7,248 MWh-equivalent) in 2023. Its source EUI of 200.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,718,576 kWh of electricity, 27,617 therms of natural gas and 5,665 thousand gallons of water for the year.

Which law requires 1635 Market to report its energy use?
