A Smart City Ecosystem Enabling Open Innovation

Conference paper
Part of the Communications in Computer and Information Science book series (CCIS, volume 1041)


In this position paper we present IT-centered challenges that lie in designing an architecture for a flexible, open, transferable, and replicable smart city ecosystem spanning a plethora of suppliers and systems. The background is the smart city and energy project +CityxChange. Its vision is to enable the co-creation and development of Positive Energy Blocks in smart sustainable cities. It will include the development of a framework and supporting tools to enable a common energy market, supported by a connected community and city integration. It will explore influences of the energy transition into city operations and urban planning, the integration of e-Mobility as a Service (eMaaS) into positive energy communities, and the growth of local trading markets and new business models. Digitalization, open architectures, and open data need to support these processes for open urban innovation in the ICT-enabled city.

+CityxChange (Positive City ExChange) is a smart city project under the Smart Cities and Communities topic that has been granted funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 824260. The main content of this paper corresponds to work that has been performed before the project start, as project development, requirements gathering, and aligning with project, city, and partner visions and approaches. It further includes initial refinements and findings within the project.

We thank our colleagues and project team members Markus Helfert, University of Limerick, and John Krogstie, NTNU, as well as the whole +CityxChange project and project preparation team for valuable discussions and contributions.
