How does Rock Creek Woods 13111-13113 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. Rock Creek Woods 13111-13113's ENERGY STAR score of 97 compares with an average of 80 across the 514 that report a score; it scores higher than 75% of them and lower than 20%. Its site EUI of 42.7 kBtu/ft² is roughly in line with the average of 43.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 30,240 sq ft, it is about 85% below the average floor area of 198,668 sq ft for those buildings. It was built in 1960, 29 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 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 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. Rock Creek Woods 13111-13113's 42.7 kBtu/ft² across 30,240 sq ft works out to about 1.3 billion Btu (378 MWh-equivalent) in 2024. Its source EUI of 67.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 112,829 kWh of electricity and 9,072 therms of natural gas for the year.
