THE IDA MARKUS FAMILY PARTNERSHIP's ENERGY STAR score of 68 compares with an average of 63 across the 22,829 that report a score; it scores higher than 49% of them and lower than 50%. Its site EUI of 74.3 kBtu/ft² is roughly in line with the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.3 kgCO₂e/ft² is about 17% below the group average of 5.2 kgCO₂e/ft².
At 53,599 sq ft, it is about half of the average floor area of 100,951 sq ft for those buildings. It was built in 1937, 15 years earlier than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. THE IDA MARKUS FAMILY PARTNERSHIP's 74.3 kBtu/ft² across 53,599 sq ft works out to about 4 billion Btu (1,167 MWh-equivalent) in 2022. Its source EUI of 96.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 167,901 kWh of electricity for the year.
