Another benefit of analytics is the ability to monitor systems that are an integral part of the client delivering the product or service to their customers. For instance, monitoring the refrigeration system in a grocery/convenience store will determine if the system is working at peak efficiency and effectiveness thereby preventing product loss due to spoilage. The criteria for peak efficiency and effectiveness are typically defined by the refrigeration case manufacturer. A typical requirement is to achieve a minimum number of defrost cycles per day to make sure the evaporator coil can achieve maximum flow, thereby protecting product from frost buildup.
Analytic software is a new class of tools for building owners, providing them real-time analysis and diagnostics of their systems and adding some "smarts” to a smart building. As John Petze, Brian Turner, Brian Thompson, Andres Szmulewicz, Mike Welch, and Jim Lee have demonstrated, it's not difficult to imagine analytic tools for other building systems and the potential for enhanced intelligence built into tools for facility management.
Fault detection and diagnostics, like other analytic software tools related to building systems, primarily supports technicians and engineers in the field who are dealing with everyday operational matters and details of building operations as well as the broader issues of complicated systems, advanced technology, and higher expectations for building performance. The fault detection and diagnostics analytic tools provide insights into building systems that help reduce energy consumption, improve building performance and lower costs. Fault detection and diagnostics does just what its name implies: It finds problems within HVAC systems and offers guidance about solving those problems.
