The main objective of the project was re-designing and re-developing a former industrial area into a sustainable new neighbourhood, providing residential, office and commercial functions. Sustainability has been considered the core principle of the whole project, expressed in terms of sustainable living, climate change adaptation, integrated water management, renewable energy production, climate change mitigation, sustainable mobility, limitation of urban sprawl, increase of green spaces. As a specific objective, the project aimed at minimising power consumption all over the process (from construction to management) and giving priority to solutions minimising maintenance requirements. The project aimed to achieve an official French “Ecodistrict” qualification and to become a “Ville de Demain – Ecocité” The water areas are combined with several green infrastructure measures. Three hectares of green public space have been created around water courses, corresponding to about 30% of the total ecodistrict area (9 hectares). At the same time water courses, that previously were channelled under the ground, have been uncovered to improve connection with green areas and 1 of their banks. Tree green corridors have been planted in order to decrease the urban heat island effect, as they can prevent part of the radiation from reaching the streets, thus creating a comfortable microclimate. A non-specified amount of vegetated rooftops will be created, which will help reducing the urban heat island effect and improve rainwater drainage.
