Public facilities are concerned by sustainable development. This implies the quality of facilities in terms of their role within the city, their use, accessibility, safety, and their technical, economic and environment performance, together with project governance. For Public Project Owners, this means being highly professional, something that they can be supported in by Certu, especially in the case of financing and supervising projects, expertise in the area of facilities, sustainable construction, asset management and liaising with innovation and research centres.
