This proposal plans to investigate, implement and validate energy neutral Smart Urban Isles (SUI), defined as “areas around a public building, which make use of the synergies between different (building) functions and of the scale advantages for energy (storage) solutions”. The project is formed by three complementary and integrated blocks: mini networks, bioclimatic and responsive building design and management platform. The mini networks include decentralised renewable energy generation, energy storage and distribution, and consider integration of (electrical) mobility. Bioclimatic design of buildings (and urban planning) with optimal integration with the mini-network will be developed, using the public building as an example. An energy management system to control and optimize energy flows will be carried out taking into account innovative ICT measures.
