How does Carlsbad N1 compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Carlsbad N1's ENERGY STAR score of 2 compares with an average of 75 across the 4,912 that report a score; it scores higher than 3% of them and lower than 97%. Its site EUI of 158.5 kBtu/ft² is about 181% 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 9.4 kgCO₂e/ft² is about 162% above the group average of 3.6 kgCO₂e/ft².
At 77,400 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 2015, 30 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 2 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 2 means the building performs better than about 2% of its national peers. BuildingCensus bands the score into report-card grades; 2 falls in band D — lowest band (1–54). It sits 73 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 N1's 158.5 kBtu/ft² across 77,400 sq ft works out to about 12.3 billion Btu (3,595 MWh-equivalent) in 2019. The disclosure also reports 3,178,621 kWh of electricity and 13,717 therms of natural gas for the year.
Which law requires Carlsbad N1 to report its energy use?
Carlsbad N1 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:12004466:2019).
