How has 29 Claremont Ave's energy performance changed over time?

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 29 Claremont Ave's 8.1 kBtu/ft² across 43,956 sq ft works out to about 0.4 billion Btu (104 MWh-equivalent) in 2024. Its source EUI of 20.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 90,823 kWh of electricity, 447 therms of natural gas and 1,226 thousand gallons of water for the year.
