Fault Detection and Diagnostics Software

This research project aims to evaluate a Fault Detection and Diagnostics (FDD) product capable of identifying problems associated with the operation of HVAC systems commonly used in commercial buildings including air-handling units, variable air volume (VAV) boxes and chilled water systems.

Three demonstration sites were selected for the emerging technology study, based on building size, existence of a network enabled building automation system (BAS) and the availability of control points found in a typical HVAC system. The FDD systems were deployed at each site which included installation of a data acquisition device capable of receiving trend data from the BAS and transmitting it to a remote database operated by the FDD software vendor.
