Building Monitoring Data and Research
Research roundups drawn from published federal agency reports, academic studies, and industry analyses. This section provides the statistical foundation behind the claims made throughout this site, with primary sources cited and linked.
What Is in This Section
Small Commercial Building Statistics
Published data on the U.S. small commercial building stock: total building count (5.9 million), size distribution (97% under 100,000 sq ft), median building age (36 years), energy use by building type, BAS adoption rates by size category, and the documented energy savings opportunity. Sources include EIA CBECS, PNNL, Nexus Labs, and CRE.
Building Monitoring Cost Data and Research
Published data on what building automation systems actually cost: the $2.50 to $7 per square foot installed range, why labor accounts for 50 to 75 percent of project budgets, the 2.3x regional cost variation documented by NREL (Dallas $779K vs. NYC $1.8M for the same 30,000 sq ft reference building), and what this cost structure means for small building economics. Sources include NREL 2022 and PNNL 2017.
How We Use and Cite Research
The research cited throughout this site comes from federal agencies (PNNL, NREL, EIA, EPA, DOE), academic institutions, and published industry analyses. We link to primary sources wherever possible so you can read the original research, not just our summary of it.
We do not cite vendor-produced research as primary evidence for market-size or savings-potential claims. Vendor studies have obvious incentive problems. Where a vendor study is the only available source on a specific point, we note it as such.
If you find an error in how we have represented a study’s findings, see our corrections policy. We update pages when errors are identified and note the correction at the bottom of the affected page.
