How does The Rapa-Nui compare with other multifamily (5+ units) buildings in Berkeley?
The latest disclosures cover 202 multifamily (5+ units) buildings in Berkeley, out of 440 buildings citywide. The Rapa-Nui's ENERGY STAR score of 100 compares with an average of 92 across the 156 that report a score; it scores higher than 56% of them. Its site EUI of 35.3 kBtu/ft² is roughly in line with the average of 32.9 kBtu/ft².
At 18,894 sq ft, it is about 43% below the average floor area of 33,316 sq ft for those buildings.
How has The Rapa-Nui's energy performance changed over time?
BuildingCensus holds 4 Berkeley disclosures for The Rapa-Nui, covering report years 2022–2025. Its ENERGY STAR score was 100 in both 2022 and 2025. Site EUI moved from 37.0 kBtu/ft² (2022) to 35.3 kBtu/ft² (2025), a 5% decrease.
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). 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 Berkeley, 82% 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. The Rapa-Nui's 35.3 kBtu/ft² across 18,894 sq ft works out to about 0.7 billion Btu (195 MWh-equivalent) in 2025. Its source EUI of 52.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 47,442 kWh of electricity and 5,057 therms of natural gas for the year.
Which law requires The Rapa-Nui to report its energy use?
The Rapa-Nui reports under BESO (BMC Chapter 19.81), the legal basis of Berkeley's Building Emissions Saving Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record berkeley:8590:2025). Berkeley's BESO requires annual benchmarking for commercial and multifamily buildings of 15,000 sq ft or more, with energy assessments at time of listing and every five years for buildings of 25,000 sq ft or more.
