With the proliferation and standardization of building automation protocols, such as BACnet and Modbus, it is easier to integrate electrical power monitoring systems (EPMS) into a facility wide maintenance and test system. Common power-use meters can help track and record loading and energy use, alerting owners to potential capacity issues or even low-load inefficiencies. Energy-performance verification is an important part of post-occupancy and may even be required in certain projects—such as data centers, where it is used to track power-usage effectiveness (PUE)—and where fuel sources and end uses are metered independently.

This information is also critical for future renovations and expansions, as consulting engineers can determine the ability to add new loads to existing systems. More sophisticated power-quality monitoring can help owners avoid damage to equipment or to identify sources of poor power quality either inside the facility or from the utility. Common alarms from various systems can be collected and presented for instant remote decision-making and action plans.

Electrical monitoring systems are making even greater strides with leading-edge systems that are “aware” of occupant use and traffic, adjusting light levels to constant illumination levels and energy use. This constant evaluation or “testing” of space use blurs the line between the roles of electrical engineers and interior architects and planners, requiring an integrated team approach to improving the performance of both electrical systems and the spaces we work and live in.

Today we have numerous requirements and optional recommended practices for testing and commissioning electrical systems.
