This book presents interdisciplinary approaches to help buildings, electrical energy networks and their users contribute to the energy and societal transition. Smart Grids and Buildings for Energy and Societal Transition examines the technologies, uses and imaginaries involved in implementing smart buildings and smart grids. Production and consumption forecasts, modeling of stakeholder involvement and self-consumption within a renewable energy community exploiting blockchain technology are examples developed with a view to fostering the emergence of smart grids. The potential of smart buildings, taking into account user comfort while increasing energy efficiency, is identified. Full-scale demonstrators are used to test the proposed solutions, and to ensure that users take full advantage of the potential for electrical flexibility.
