| Resumo: | Early fault detection and diagnosis in heating, ventilation and air conditioning (HVAC)systems may reduce the damage of equipment, improving the reliability and safety of smart buildings,generating social and economic benefits. Data models for fault detection and diagnosis are increasinglyused for extracting knowledge in the supervisory tasks. This article proposes an autonomic cycle ofdata analysis tasks (ACODAT) for the supervision of the building'sHVAC systems. Data analysis tasksincorporate data mining models for extracting knowledge from the system monitoring, analyzingabnormal situations and automatically identifying and taking corrective actions. This article shows acase study of a real building's HVAC system, for the supervision with our ACODAT, where the HVACsubsystems have been installed over the years, providing a good example of a heterogeneous facility.The proposed supervisory functionality of the HVAC system is capable of detecting deviations, suchas faults or gradual increment of energy consumption in similar working conditions. The case studyshows this capability of the supervisory autonomic cycle, usually a key objective for smart buildings. |
