Newly released data tables from the Energy Information Administration’s 2018 Commercial Buildings Energy Consumption Survey (CBECS) provide building characteristics information for the estimated 5.9 million U.S. commercial buildings in 2018.
Building characteristics data tables include number of workers, ownership and occupancy, structural characteristics, energy sources and uses, energy related building features, and more.
In the lighting side, it shows us that adoption of LED lighting and occupancy sensors have increased considerably in terms of lighted commercial floorspace, with all traditional sources declining, notably linear fluorescent.
I wrote up a detailed look at the salient building and lighting data available in this most recent version of the CBECS for the Lighting Controls Association. Check it out here.
