How has The Schwab House's energy performance changed over time?

Its ENERGY STAR score went from 96 in 2023 to 91 in 2024 (-5 points); its best year on file was 2023, at 96. Site EUI moved from 50.7 kBtu/ft² (2023) to 63.3 kBtu/ft² (2024), an 25% increase. Reported emissions went from 2,141 tCO₂e to 2,567 tCO₂e over the same span (up 20%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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 New York City, 43% 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 Schwab House's 63.3 kBtu/ft² across 645,471 sq ft works out to about 40.9 billion Btu (11,974 MWh-equivalent) in 2024. Its source EUI of 83.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,880,400 kWh of electricity, 344,339 therms of natural gas and 18,477 thousand gallons of water for the year.
