How has The Marine Building's energy performance changed over time?
BuildingCensus holds 2 Portland disclosures for The Marine Building, covering report years 2023–2024. Its ENERGY STAR score went from 91 in 2023 to 97 in 2024 (+6 points). Site EUI moved from 32.2 kBtu/ft² (2023) to 24.1 kBtu/ft² (2024), a 25% decrease. Reported emissions went from 108 tCO₂e to 86 tCO₂e over the same span (down 20%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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 Portland, 66% 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 Marine Building's 24.1 kBtu/ft² across 40,586 sq ft works out to about 1 billion Btu (287 MWh-equivalent) in 2024. The disclosure also reports 244,611 kWh of electricity and 1,432 therms of natural gas for the year.
Which law requires The Marine Building to report its energy use?
The Marine Building reports under the Commercial Building Energy Performance Reporting Policy, the legal basis of Portland's Commercial Building Energy Reporting program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record portland_or:1N1E33AB-4500-B1:2024).
