ChArGED: Implementing a framework for improving energy efficiency in public buildings through IoTenabled energy disaggregation and serious games

This paper reports on the approach for the design and development of the H2020 ChArGED project framework. ChArGED addresses energy wastage and proposes a framework that aims to facilitate achieving greater energy efficiency in public buildings. The framework leverages IoT-enabled low-cost devices, to improve energy disaggregation mechanisms that provide energy use and -consequently- wastage information at the device, area and end-user level. The identified wastages are concurrently targeted by a gamified application that feeds personalized real-time recommendations to each individual enduser. The ChArGED solution is being developed iteratively, with the end-users' engagement during the analysis, design and development phases in public buildings located in 3 different countries: Luxembourg (Musée National d'Histoire et d'Art), Spain (EcoUrbanBuilding, Institut Català d'Energia headquarters, Barcelona) and Greece (General Secretariat of the Municipality of Athens).
