Lantern Cove - 51012's ENERGY STAR score of 79 compares with an average of 82 across the 9,612 that report a score; it scores higher than 31% of them and lower than 68%. Its site EUI of 42.1 kBtu/ft² is about 22% above the average of 34.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.6 kgCO₂e/ft² is about 24% above the group average of 2.1 kgCO₂e/ft².
At 228,004 sq ft, it is about 51% above the average floor area of 150,919 sq ft for those buildings. It was built in 1985, 3 years earlier than the group's average year built (1988). 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 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 falls in band B — above median (70–84). 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 California, 65% 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. Lantern Cove - 51012's 42.1 kBtu/ft² across 228,004 sq ft works out to about 9.6 billion Btu (2,813 MWh-equivalent) in 2022. The disclosure also reports 784,504 kWh of electricity and 75,011 therms of natural gas for the year.
