Its emissions intensity of 3.0 kgCO₂e/ft² is about 76% above the group average of 1.7 kgCO₂e/ft².
At 156,856 sq ft, it is about 59% above the average floor area of 98,872 sq ft for those buildings. It was built in 1920, 63 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 28.5 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 #1984's 28.5 kBtu/ft² across 156,856 sq ft works out to about 4.5 billion Btu (1,310 MWh-equivalent) in 2023. Its source EUI of 78.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,265,183 kWh of electricity, 1,462 therms of natural gas and 8 thousand gallons of water for the year.
Which law requires MMS #1984 to report its energy use?
