Lakeview House Apartments's ENERGY STAR score of 68 compares with an average of 80 across the 514 that report a score; it scores higher than 20% of them and lower than 79%. Its site EUI of 59.9 kBtu/ft² is about 39% above the average of 43.2 kBtu/ft² — it uses more energy per square foot than the typical building in that group.

At 127,631 sq ft, it is about 36% below the average floor area of 198,668 sq ft for those buildings. It was built in 1978, 11 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 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. Lakeview House Apartments's 59.9 kBtu/ft² across 127,631 sq ft works out to about 7.6 billion Btu (2,241 MWh-equivalent) in 2024. Its source EUI of 105.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 905,462 kWh of electricity and 45,530 therms of natural gas for the year.

Which law requires Lakeview House Apartments to report its energy use?
