What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. York Square Condominium Association's 33.7 kBtu/ft² across 1,898 sq ft works out to about 0.1 billion Btu (19 MWh-equivalent) in 2024. Its source EUI of 74.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 677,372 kWh of electricity, 11,640 therms of natural gas and 1,749 thousand gallons of water for the year.

Which law requires York Square Condominium Association to report its energy use?

York Square Condominium Association reports under Phila. Code §9-3402 / Building Energy Performance Program, the legal basis of Philadelphia's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results.
