How has Marina Towers North's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Marina Towers North, covering report years 2018, 2019, 2021, 2022, 2023, 2024. Its ENERGY STAR score went from 83 in 2018 to 96 in 2024 (+13 points). Site EUI moved from 39.3 kBtu/ft² (2018) to 31.6 kBtu/ft² (2024), a 20% decrease. Reported emissions went from 567 tCO₂e to 413 tCO₂e over the same span (down 27%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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 North's 31.6 kBtu/ft² across 197,985 sq ft works out to about 6.3 billion Btu (1,834 MWh-equivalent) in 2024. The disclosure also reports 1,671,260 kWh of electricity and 6,529 therms of natural gas for the year.
Which law requires Marina Towers North to report its energy use?
