Bailey

How does Bailey compare with other office buildings in Philadelphia?

The latest disclosures cover 212 office buildings in Philadelphia, out of 2,379 buildings citywide. Bailey's ENERGY STAR score of 76 compares with an average of 64 across the 180 that report a score; it scores higher than 62% of them and lower than 33%. Its site EUI of 28.5 kBtu/ft² is about 64% below the average of 78.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 49,344 sq ft, it is about 83% below the average floor area of 292,223 sq ft for those buildings. It was built in 1950, 7 years earlier than the group's average year built (1957). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has Bailey's energy performance changed over time?

BuildingCensus holds 6 Philadelphia disclosures for Bailey, covering report years 2019–2024. Its ENERGY STAR score went from 55 in 2019 to 76 in 2024 (+21 points); its best year on file was 2021, at 87. Site EUI moved from 39.8 kBtu/ft² (2019) to 28.5 kBtu/ft² (2024), a 28% decrease. Reported emissions went from 212 tCO₂e to 140 tCO₂e over the same span (down 34%).

What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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. Bailey's 28.5 kBtu/ft² across 49,344 sq ft works out to about 1.4 billion Btu (412 MWh-equivalent) in 2024. Its source EUI of 79.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 466,039 kWh of electricity and 148 thousand gallons of water for the year.

Which law requires Bailey to report its energy use?

Bailey 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. The record shown here is the report-year 2024 disclosure (source record philadelphia:3859412:2024). Philadelphia requires commercial and multifamily buildings of 50,000+ sq ft to benchmark annually; its Building Energy Performance Program additionally requires non-residential buildings of 50,000+ sq ft to complete a tune-up or certify as high-performance every five years, with fines starting at $2,000 for non-compliance.
