Nevada City Senior's ENERGY STAR score of 70 compares with an average of 82 across the 9,612 that report a score; it scores higher than 22% of them and lower than 77%. Its site EUI of 55.3 kBtu/ft² is about 61% 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 3.2 kgCO₂e/ft² is about 52% above the group average of 2.1 kgCO₂e/ft².
At 75,123 sq ft, it is about half of the average floor area of 150,919 sq ft for those buildings. Its 1991 construction date is close to 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 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. 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. Nevada City Senior's 55.3 kBtu/ft² across 75,123 sq ft works out to about 4.2 billion Btu (1,218 MWh-equivalent) in 2022. The disclosure also reports 361,696 kWh of electricity and 28,801 therms of natural gas for the year.
Which law requires Nevada City Senior to report its energy use?
Nevada City Senior reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2022 disclosure (source record california:28092709:2022).
