As a system that can share data seamlessly over one network, one cable, and one connection, PoE can reveal a lot of useful information to building owners and managers. By connecting occupancy sensors, CO₂ detectors, video cameras, and much more, PoE can be the spinal cord of an entire building, communicating data related to, for example, the use of space. If monitoring shows little activity in a particular room or area, then this knowledge can serve as the basis for re-purposing the space or adjusting staff objectives.

On a grander scale, intelligent monitoring can maximize usage of a space and could enhance profitability and impact a company’s bottom line. The big picture estimate of a company’s costs per square foot is represented by the 3-30-300 rule (see diagram), which puts into perspective how an organization’s occupancy cost is typically distributed: $3/sq ft for utilities, $30/sq ft for rent, and $300/sq ft for their employee costs (salaries, benefits, etc.). Many facility managers usually focus on the $3 and $30 parts of the framework as the areas on which they can make the largest impact. However, since PoE can provide information that allows for a better understanding of employee productivity and satisfaction, an impact can, in fact, be made on the $300/sq ft spend on salaries.
