DR-BOB aims to demonstrate the economic and environmental benefits of demand response in blocks of buildings, therefore helping with the inefficient utilization of intermittent generation plants to match electricity demand. Blocks of buildings offer more flexibility in the timing of energy use, local energy generation and energy storage, but a lack of suitable products and technologies make this problematic. DR BOB is developing tools to: manage the request coming from the TSO; define optimization strategies to answer to the above requests; communicate information to the facility managers and engage occupants. The technologies will be tested at: Teesside University campus in Middlesbrough in the UK; A business and technology park in Anglet in France; A hospital complex in Brescia in Italy; The campus of the Technical University of Cluj Napoca in Romania.
