Carlsbad W5's ENERGY STAR score of 19 compares with an average of 75 across the 4,912 that report a score; it scores higher than 6% of them and lower than 94%. Its site EUI of 93.5 kBtu/ft² is about 66% above the average of 56.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.5 kgCO₂e/ft² is about 52% above the group average of 3.6 kgCO₂e/ft².
At 60,000 sq ft, it is about 61% below the average floor area of 151,937 sq ft for those buildings. It was built in 2006, 21 years later than the group's average year built (1985). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 19 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 19 means the building performs better than about 19% of its national peers. BuildingCensus bands the score into report-card grades; 19 falls in band D — lowest band (1–54). It sits 56 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. Carlsbad W5's 93.5 kBtu/ft² across 60,000 sq ft works out to about 5.6 billion Btu (1,644 MWh-equivalent) in 2019. The disclosure also reports 1,171,181 kWh of electricity and 16,206 therms of natural gas for the year.
Which law requires Carlsbad W5 to report its energy use?
Carlsbad W5 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 2019 disclosure (source record california:12004547:2019).
