For Indoor Smart Grids (ISG), the proper operation of building environmental systems is essential to energy efficiency, so automatic detection and classification of abnormal conditions is important. The application of computational intelligence tools to a building's environmental systems that include the Building Automation System (BAS) and Heating Ventilating and Air Conditioning (HVAC) loads, is used to develop Automatic Building Diagnostic Software (ABDS) Tools for health monitoring, fault detection, and diagnostics. A novel Health Monitoring System (HMS) for a Variable Air Volume Unit is developed using fuzzy logic to detect abnormal operating conditions and to generate fault signatures for various fault types. Artificial Neural Network software is applied to fault signatures to classify the fault type. The HMS is tested with simulated data and actual BAS data. The system created was demonstrated to recognize faults and to accurately classify the various fault signatures for test faults of interest.
