Automated fault detection and diagnosis (AFDD) for HVAC systems in buildings detects and identifies operational faults based on the analysis of measured system behaviors. AFDD is critical in achieving the goal of building energy efficiency, reducing or eliminating energy waste in buildings caused by operational faults, and ensuring the persistence of building commissioning. This seminar presents new AFDD methods and research development for HVAC systems including functional performance test-based, inverse model-based, and evolving learning-based AFDD methods. The seminar also presents AFDD testing results and lessons learned based on the implementation of the new AFDD methods into several existing buildings.
