ANN Radar - Hamburg, Germany

Status: In Progress

In Hamburg, HafenCity University is implementing the project ANN (A New Normal) RADAR, aimed at identifying spaces and districts that can be used as urban testbeds for prototyping energy innovations. The identification will be made through an interactive decision support tool, based on public and private environmental, climate and energy data of different districts in the city. The ANN RADAR tool was inspired by A New Normal in Melbourne, Australia, aimed at prototyping and piloting in the context of a sustainable Melbourne 2030.

ANN RADAR evaluates local climate and sustainability strategies and specific environmental monitoring data available in Hamburg. The project enables stakeholders to identify urban spaces as testbeds for prototypes and pilots in alignment with local climate mitigation goals.

ANN RADAR will focus on three main fields of local climate action:

  • sustainable mobility
  • sustainable energy efficient buildings
  • solar energy development

Local scene



Since its successful application for the European Green City award in 2011, Hamburg has worked to strengthen its environmental commitments. With the release of an updated climate plan in 2019 and a new climate protection law, the Senate has made two important steps to achieve local climate goals to strengthen climate ambitions:

  • CO2 emissions are to be reduced by 55 percent by 2030
  • Hamburg is to become climate-neutral by 2050 (Hamburg Klimaplan 2020)

In various urban sustainability sectors, the city has been developing pilot projects and ‘Living Labs’ in the spirit of urban experimentation to see what ‘works’ and then based on initial evaluation upscale, replicate or make permanent successful interventions (Experimental Governance). The practice provides important testbeds for experimenting with new technologies and social innovations, but also raise awareness and acceptance of such interventions amongst citizens and other stakeholders. Key to successful experimentations is an effective evidence-based process to identify target locations and to demonstrate success (or failure). ANN RADAR addresses this challenge through a data-driven evidence base, by identifying areas that have a particular demand and provide ample context for experimental interventions and support with the evaluation of their effectiveness.

HafenCity University



Located in Hamburg, Germany, HafenCity University – University for the Built Environment and Metropolitan Studies - is specialized on sustainable cities and the built environment, including competencies in engineering, natural, social and cultural sciences. Cooperating in a broad international network throughout Europe and the world, the HCU is driven by research, encompassing basic research, applied research as well as design research.

HafenCity's proposal for the ANN Radar was chosen to receive funding through the ICLEI Action Fund because of its integrated approach involving different topics - such as solar potential, energy efficiency and mobility - and for its connection with urban data. The added value was the connection to existing plans and projects (SECAP, SUMP, mySmartLife, IURC) and the potential to scale up the support tool within the City of Hamburg and transfer to other cities.
