How does National Park Seminary compare with other multifamily housing buildings in Montgomery County?

The latest disclosures cover 553 multifamily housing buildings in Montgomery County, out of 1,766 buildings citywide. National Park Seminary's ENERGY STAR score of 67 compares with an average of 80 across the 514 that report a score; it scores higher than 20% of them and lower than 80%. Its site EUI of 31.3 kBtu/ft² is about 28% below the average of 43.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 100,271 sq ft, it is about half of the average floor area of 198,668 sq ft for those buildings. It was built in 1928, 61 years earlier than the group's average year built (1989). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. In Montgomery County, 53% 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. National Park Seminary's 31.3 kBtu/ft² across 100,271 sq ft works out to about 3.1 billion Btu (920 MWh-equivalent) in 2024. Its source EUI of 77.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 743,712 kWh of electricity and 6,008 therms of natural gas for the year.

Which law requires National Park Seminary to report its energy use?

National Park Seminary reports under the Benchmarking Law (Bill 2-14) / BEPS (Bill 16-21), the legal basis of Montgomery County's Commercial Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results.
