Its site EUI of 223.4 kBtu/ft² is about half of the average of 409.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 16.5 kgCO₂e/ft² is about 43% below the group average of 28.8 kgCO₂e/ft².
At 34,329 sq ft, it is about 88% below the average floor area of 293,236 sq ft for those buildings. It was built in 1939, 26 years earlier than the group's average year built (1966). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
What does a site EUI of 223.4 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. Old Public Health Building's 223.4 kBtu/ft² across 34,329 sq ft works out to about 7.7 billion Btu (2,248 MWh-equivalent) in 2022. Its source EUI of 428.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,025,654 kWh of electricity for the year.
