How does Towne Partners LLC compare with other K-12 school buildings in New York City?
The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. Towne Partners LLC's ENERGY STAR score of 3 compares with an average of 64 across the 2,052 that report a score; it scores higher than 2% of them and lower than 98%. Its site EUI of 106.7 kBtu/ft² is about 74% above the average of 61.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 9.4 kgCO₂e/ft² is about twice the group average of 4.8 kgCO₂e/ft².
At 51,614 sq ft, it is about half of the average floor area of 101,338 sq ft for those buildings. It was built in 1997, 44 years later than the group's average year built (1954). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².
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. Towne Partners LLC's 106.7 kBtu/ft² across 51,614 sq ft works out to about 5.5 billion Btu (1,614 MWh-equivalent) in 2023. Its source EUI of 229.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,018,429 kWh of electricity, 20,315 therms of natural gas and 5,184 thousand gallons of water for the year.
