Dublin counts half a million residents. Its energy agency CODEMA is in the early stages of redesigning the city’s energy landscape by involving the local community.

She will explain what changes can be expected in the city and describes how she and her team trigger conversations with citizens around very abstract topics such as district heating using waste heat from data centres.
