The Building Monitoring Learning Center
Vendor-neutral, research-backed guides on building automation, indoor air quality, energy efficiency, and the standards that govern commercial building environments. Written for building owners and facility managers, not engineers.
What You Will Find Here
FractionalBAS.com publishes vendor-neutral educational content on building monitoring, indoor air quality, energy efficiency, and compliance for small commercial buildings. Every article is written from primary research, cites government and academic sources, and is reviewed by someone who has actually deployed sensor systems in commercial buildings. No sponsored content. No product endorsements. Just the information building operators need to make better decisions.
The guides in this section cover the foundational topics every commercial building owner or facility manager should understand: what a building automation system is and why most small buildings do not have one, what indoor air quality means and how it affects the people inside the building, how energy efficiency works at the operational level, what building monitoring looks like as a standalone practice, and which standards and regulations apply to commercial buildings of different types and sizes.
Start With the Topic That Matters Most to Your Building
Each guide below covers a foundational topic in depth, with data from primary research sources, practical context for small commercial buildings, and links to more specific articles within each topic area.
What Is a Fractional BAS?
The concept at the center of this site: a monitoring-first approach that delivers the core benefits of building automation for the 87 percent of small commercial buildings that cannot afford a full BAS. Start here if you are new to the topic.
Building Automation Systems (BAS)
What a BAS is, how its five-layer architecture works, what it costs, and why 87 percent of small commercial buildings operate without one. Includes the PNNL energy savings data and a three-way comparison of monitoring options.
Indoor Air Quality
CO2, VOCs, humidity, particulate matter, temperature, and radon: what each parameter means, why it matters for occupants, and how the standards (ASHRAE 62.1, WELL, RESET) set the thresholds that apply to your building.
Energy Efficiency
Where energy goes in a commercial building, which operational changes deliver the largest savings without capital investment, and how to benchmark your building against national averages using Energy Use Intensity (EUI) and CBECS data.
Building Monitoring
What building monitoring means as an operational practice, how continuous monitoring differs from spot checks, the three levels of monitoring available to commercial buildings, and how to start a monitoring program without a major capital project.
Compliance and Standards
ASHRAE 62.1, ASHRAE 55, ASHRAE 90.1, OSHA, NYC Local Law 97, WELL, and RESET: which standards apply to your building, what compliance actually requires, and how continuous monitoring supports both baseline compliance and higher-performance certification.
Guides, Verticals, and Data Resources
Beyond the foundational topic guides, FractionalBAS.com publishes buying guides for building owners evaluating monitoring options, vertical-specific resources for particular building types, and data pages synthesizing published research on the small commercial building market.
Buying Guides
For building owners actively evaluating monitoring and automation options. Guides cover fractional BAS versus full BAS, realistic cost breakdowns, how to choose a monitoring system, and a step-by-step buying checklist. These are the highest-purchase-intent pages on the site, written for people who are ready to decide.
Building Type Guides
Monitoring challenges, regulatory obligations, and energy profiles vary significantly by building type. Vertical guides are available for schools, municipal buildings, offices, food service, healthcare outpatient facilities, warehouses, and hospitality properties. Each addresses the specific concerns of operators in that building category.
Market Data and Research
Data pages synthesizing published research on the small commercial building market: building stock statistics, monitoring cost data, and annual research roundups. These pages are citation-dense and designed for building owners, energy consultants, and researchers who want the underlying numbers.
