How has Logan Lofts's energy performance changed over time?
BuildingCensus holds 6 Philadelphia disclosures for Logan Lofts, covering report years 2019–2024. Its ENERGY STAR score went from 74 in 2019 to 76 in 2024 (+2 points); its best year on file was 2022, at 86. Site EUI moved from 37.0 kBtu/ft² (2019) to 35.4 kBtu/ft² (2024), a 4% decrease. Reported emissions went from 364 tCO₂e to 274 tCO₂e over the same span (down 25%).
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. Logan Lofts's 35.4 kBtu/ft² across 1,009 sq ft works out to about 0 billion Btu (10 MWh-equivalent) in 2024. Its source EUI of 99.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,006,888 kWh of electricity and 4,797 thousand gallons of water for the year.
Which law requires Logan Lofts to report its energy use?
