The U.S. Department of Energy recently released preliminary results of the 2018 Commercial Buildings Energy Consumption Survey (CBECS). Conducted every five (approximately) years, the CBECS estimates characteristics for the national building stock.

The preliminary data release includes number of buildings, square footage, and age of buildings by size, principal activity, year of construction, and census region and division.

The next release (in spring or summer of 2021) will include more detailed building characteristics, which I’m hoping will again include adoption of various lighting strategies.

Some key takeaways:

  • Number of buildings grew 6% since 2012, floorspace 11%; building size continues to grow faster than number of buildings
  • Most buildings are small, though large buildings have more total floorspace
  • Office, warehouse/storage, and service buildings are most common type
  • Fastest-growing building markets since 2012 were lodging, service, and public assembly
  • More than 50% of buildings were built 1960-1999, with 25% built since 2000
