ChArGED (CleAnweb Gamified Energy Disaggregation) addresses the energy consumption in public buildings and proposes a framework that aims to facilitate achieving greater energy efficiency and reductions of wasted energy in public buildings. The framework leverages IoT enabled, low-cost devices (NFC or iBeacons) to improve energy disaggregation mechanisms that provide energy use and -consequently- wastages at the device, area and end user level. These wastages are targeted by a gamified application that feeds personalized real-time recommendations to each individual end user. The design of the game follows a cleanweb approach and implements a novel social innovation process that is designed based on human inceptives factors and helps users to understand the environmental implications of their actions and adopt a greener, more active and responsible behaviour. Efficient energy use renders its consumption predictable and this is exploited by the ChArGED gamified application to optimize use of the micro-generated energy.
