Actions

1st- Turn a public urbanisation into a research andexperimentation centre based on a sustainablecity planning.

2nd- Through its monitoring in real time, once theplanning has been made, the buildings becomepermanent experimental places, allowing us toconfirm the conditions set in the construction as
