Application of fault detection and diagnosis techniques to automated functional testing

Extensive research in the field of fault detection and diagnosis has produced useful tools and techniques that have been applied to continuously operating building HVAC systems. A few researchers have applied some of these to commissioning of new buildings. This paper reports on a project that adapted or developed models of air-handling unit components and controls and combined them into an automated functional testing tool. Operation of the tool is demonstrated in testing a real air-handling unit.
