The former industrial area “Luciline” in Rouen, along the Seine river, has been re-designed profoundly into an ecodistrict (9 hectares in total), including both climate change adaptation and mitigation solutions. Sustainable living is the core principle of the neighbourhood re-design. Sustainability aspects are implemented by means of energy, water, biodiversity, transport and planning solutions that in most of the case play an important role for climate change adaption or mitigation. Measures include: a system of small canals connected to the Seine river improving drainage of water from buildings (rooftops in particular) and open spaces, green areas and tree corridors, heating and cooling system using ground water (prior to its release to the Seine River), energy saving in buildings, good access to public transport, easy accessibility of the area by foot and bicycle and compact building planning.
