Ville Aménagement Durable mobilises and animates a network of more than 2,000 professionals around the issues of sustainable building and planning. The project is based on feedback, debate, training and information to enable the development of competence, the development of the competitiveness of companies, the creation of synergy and partnerships throughout the value chain of the act of building and planning. With the support of the 4 strategic axes, the VAD project innovates, shares and prepares for the future. VAD therefore sets up 4 types of accompaniment. This is VISON: highlights for setting broad directions, a forward-looking approach to defining priorities and methodology. LAB: feedback from the ground to observe and capitalise, a global approach to identify, analyse and share good practices. INITIATIVES: building together the territories of tomorrow. The discussion and debate to animate the network and project itself. Finally, DIFFUSION: data to understand and advance: the rich documentary multi-media to raise awareness, train, inform. The project is positioned as a multidisciplinary tool at the service of professionals in the territory that it mobilises and accompanies directly by bringing together a panel of actions. The collective actions that federate and involve the business ecosystem are the driving force behind the project.
