From fault-detection to automated fault correction: A field study

A fault detection and diagnostics (FDD) tool, as addressed by this study, is a tool that continuously identifies the presence of faults efficiency improvement opportunities through one-way interface to building automation system application automated analytics. Although FDD tools can inform operators operational faults, currently an action always required correct generate energy savings. Fault auto-correction integrating with commercial technology offerings close loop between passive active control, increase savings generated tools, reduce reliance on human intervention. This paper presents field study seven algorithms implemented in platforms. Implementation includes software changes additional controls hardware or BAS were enable execution different types real buildings. The routines successfully automatically improve operation large built-up Heating, Ventilation, Air Conditioning (HVAC) systems, common most are tested across four buildings three following rigorous procedure make sure they work properly do not negatively impact occupants. Technology benefits, market drivers, scalability drawn from implementation effort test results, drive future research industry engagement.
