How has Mercantile Building's energy performance changed over time?

BuildingCensus holds 2 Philadelphia disclosures for Mercantile Building, covering report years 2019–2020. Its ENERGY STAR score went from 97 in 2019 to 87 in 2020 (-10 points); its best year on file was 2019, at 97. Site EUI moved from 19.9 kBtu/ft² (2019) to 23.9 kBtu/ft² (2020), an 20% increase. Reported emissions went from 115 tCO₂e to 129 tCO₂e over the same span (up 12%).

What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Mercantile Building's 23.9 kBtu/ft² across 58,000 sq ft works out to about 1.4 billion Btu (406 MWh-equivalent) in 2020. Its source EUI of 64.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 383,201 kWh of electricity, 769 therms of natural gas and 1,123 thousand gallons of water for the year.

Which law requires Mercantile Building to report its energy use?
