How has The Lanesborough's energy performance changed over time?
BuildingCensus holds 6 Philadelphia disclosures for The Lanesborough, covering report years 2019–2024. Its ENERGY STAR score went from 95 in 2019 to 97 in 2024 (+2 points); its best year on file was 2020, at 97. Site EUI moved from 39.9 kBtu/ft² (2019) to 35.7 kBtu/ft² (2024), a 11% decrease. Reported emissions went from 292 tCO₂e to 250 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. The Lanesborough's 35.7 kBtu/ft² across 3,513 sq ft works out to about 0.1 billion Btu (37 MWh-equivalent) in 2024. Its source EUI of 74.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 588,462 kWh of electricity, 13,810 therms of natural gas and 477 thousand gallons of water for the year.
