Carriage Wheel Lofts

How does Carriage Wheel Lofts compare with other multifamily housing buildings in Philadelphia?

The latest disclosures cover 768 multifamily housing buildings in Philadelphia, out of 2,379 buildings citywide. Carriage Wheel Lofts's ENERGY STAR score of 83 compares with an average of 59 across the 682 that report a score; it scores higher than 67% of them and lower than 32%. Its site EUI of 24.7 kBtu/ft² is about 56% below the average of 55.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 52,260 sq ft, it is about 58% below the average floor area of 125,469 sq ft for those buildings. It was built in 2020, 49 years later than the group's average year built (1971). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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. Carriage Wheel Lofts's 24.7 kBtu/ft² across 52,260 sq ft works out to about 1.3 billion Btu (378 MWh-equivalent) in 2021. Its source EUI of 69.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 378,445 kWh of electricity and 1,836 thousand gallons of water for the year.

Which law requires Carriage Wheel Lofts to report its energy use?

Carriage Wheel Lofts 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 2021 disclosure (source record philadelphia:21468162:2021). 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.
