How does MMS #1992 compare with other self-storage facility buildings in New York City?
The latest disclosures cover 481 self-storage facility buildings in New York City, out of 48,310 buildings citywide. Its site EUI of 7.1 kBtu/ft² is about 67% below the average of 21.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.8 kgCO₂e/ft² is about half of the group average of 1.7 kgCO₂e/ft².
At 124,385 sq ft, it is about 26% above the average floor area of 98,872 sq ft for those buildings. It was built in 1928, 55 years earlier than the group's average year built (1983). Across all 24 jurisdictions BuildingCensus covers, the 3,050 self-storage facility buildings average an ENERGY STAR score of 75 and a site EUI of 9.4 kBtu/ft².
What does a site EUI of 7.1 kBtu/ft² mean?
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. MMS #1992's 7.1 kBtu/ft² across 124,385 sq ft works out to about 0.9 billion Btu (259 MWh-equivalent) in 2023. Its source EUI of 19.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 257,940 kWh of electricity and 27 thousand gallons of water for the year.
Which law requires MMS #1992 to report its energy use?
MMS #1992 reports under Local Law 84 (LL84), the legal basis of New York City's Energy and Water Data Disclosure program, which publishes each covered building's annual benchmarking results.
