STARDUST serves as smart connector bringing together advanced European cities and citizens of Pamplona (ES), Tampere (FI) and Trento (IT) - with the associated follower cities of Derry (UK), Kozani (GR) and Litomerice (CZ). These six cities, collaborating with relevant industrial partners, including a variety of innovative local SME, and supported by academia and research centres will demonstrate three lighthouse cities, deploy intelligent integration measures, test and validate technical solutions and innovative business models, and deliver blueprints for replication throughout Europe and abroad. The objective of STARDUST project is to pave the way towards the transformation of the carbon supplied cities into Smart, high efficient, intelligent and citizen oriented cities, developing urban technical green solutions and innovative business models, integrating the domains of buildings, mobility and efficient energy through ICT, testing and validating these solutions, enabling their fast roll out in the market . The core idea of the STARDUST project is the demonstration of different “innovation islands” as urban incubators of technological, social, regulatory and market solutions which, once validated, could contribute to this objective of transformation of our cities towards Smart Cities. The integrated approach of STARDUST is based in the combination of technological solutions with human being reflected in joint decision making, economic constraints, citizen’s governance, etc. The STARDUST Smart City concept has been designed to enhance the integration of all these aspects to define a new Urban Metabolism.
