How does Translational Research Lab at University of Pennsylvania compare with other office buildings in Philadelphia?
The latest disclosures cover 212 office buildings in Philadelphia, out of 2,379 buildings citywide. Translational Research Lab at University of Pennsylvania's ENERGY STAR score of 90 compares with an average of 64 across the 180 that report a score; it scores higher than 89% of them and lower than 8%. Its site EUI of 33.5 kBtu/ft² is about 57% below the average of 78.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 125,000 sq ft, it is about 57% below the average floor area of 292,223 sq ft for those buildings. It was built in 1948, 9 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.
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. Translational Research Lab at University of Pennsylvania's 33.5 kBtu/ft² across 125,000 sq ft works out to about 4.2 billion Btu (1,227 MWh-equivalent) in 2020. Its source EUI of 92.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,199,950 kWh of electricity, 933 therms of natural gas and 9,235 thousand gallons of water for the year.
Which law requires Translational Research Lab at University of Pennsylvania to report its energy use?
Translational Research Lab at University of Pennsylvania reports under Phila.
