The Faculty of Engineering conducts research that has relevance to Energy and Environment. For example, some research is concerned with providing households with real-time information about the consumption of individual electric appliances, which can result in significant electric energy savings. This research work proposes a nonintrusive appliance load monitoring system consisting of three modules: centralized data acquisition, feature extraction, and classification.Another research focuses on maximizing the power of PhotoVoltaic (PV) systems that are considered one of the most promising renewable energies. Indeed, they are pollution free, reliable and easy to implement. Other research areas investigate renewable energy applications, thermal comfort, energy efficiency, performance of construction materials, and oil spill pollution.
