Maryland Coop Apt's ENERGY STAR score of 84 compares with an average of 83 across the 1,652 that report a score; it scores higher than 36% of them and lower than 62%. Its site EUI of 31.3 kBtu/ft² is about 10% below the average of 34.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is roughly in line with the group average of 0.7 kgCO₂e/ft².
At 22,532 sq ft, it is about 74% below the average floor area of 86,468 sq ft for those buildings. It was built in 1910, 73 years earlier than the group's average year built (1983).

How has Maryland Coop Apt's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Maryland Coop Apt, covering report years 2015–2025. Its ENERGY STAR score went from 79 in 2015 to 84 in 2025 (+5 points). Site EUI moved from 32.3 kBtu/ft² (2015) to 31.3 kBtu/ft² (2025), a 3% decrease. Reported emissions went from 18 tCO₂e to 15 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 falls in band B — above median (70–84). 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 Seattle, 69% 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. Maryland Coop Apt's 31.3 kBtu/ft² across 22,532 sq ft works out to about 0.7 billion Btu (207 MWh-equivalent) in 2025. Its source EUI of 69.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 137,808 kWh of electricity and 2,344 therms of natural gas for the year.
Which law requires Maryland Coop Apt to report its energy use?
Maryland Coop Apt reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record seattle:25181:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
