Its site EUI of 53.5 kBtu/ft² is roughly in line with the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.5 kgCO₂e/ft² is roughly in line with the group average of 3.6 kgCO₂e/ft².
At 179,641 sq ft, it is about 18% above the average floor area of 151,937 sq ft for those buildings. It was built in 1970, 15 years earlier 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.
How has Marina Towers South's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Marina Towers South, covering report years 2018, 2019, 2021, 2022, 2023, 2024. Its ENERGY STAR score went from 80 in 2018 to 90 in 2024 (+10 points); its best year on file was 2021, at 95. Site EUI moved from 104.2 kBtu/ft² (2018) to 53.5 kBtu/ft² (2024), a 49% decrease. Reported emissions went from 1,363 tCO₂e to 631 tCO₂e over the same span (down 54%).
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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 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. Marina Towers South's 53.5 kBtu/ft² across 179,641 sq ft works out to about 9.6 billion Btu (2,817 MWh-equivalent) in 2024. The disclosure also reports 1,297,680 kWh of electricity and 63,397 therms of natural gas for the year.
Which law requires Marina Towers South to report its energy use?
Marina Towers South 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 2024 disclosure (source record california:1614829:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
