Reported emissions went from 926 tCO₂e to 1,126 tCO₂e over the same span (up 22%).
What does an ENERGY STAR score of 3 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 3 means the building performs better than about 3% of its national peers. BuildingCensus bands the score into report-card grades; 3 falls in band D — lowest band (1–54). It sits 72 points below 75, the threshold for ENERGY STAR certification. 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. CORSI HOUSES's 163.8 kBtu/ft² across 112,100 sq ft works out to about 18.4 billion Btu (5,381 MWh-equivalent) in 2024. Its source EUI of 209.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 712,876 kWh of electricity and 159,243 therms of natural gas for the year.
