Building on its successful experience with the Vermont house, ECOxIA has developed the Smart Building Envelope, SBE, which complies with the latest regulations and above, reaching the level of Positive Energy Buildings and the international Passive label.
ECOxIA is a supplier of eco-construction, like an OEM. Our concept of the Smart Building Envelope brings together in a single package all the items that have an impact on the energy performance. ECOxIA thus brings you an exclusive solution to offer low-carbon buildings, from construction to operations.
You remain in control of the other dimensions of the constructive project and we count on your professionalism to achieve the remaining construction tasks/lots and provide solutions essential to any building project (land, permits, financing, etc.).
