The Building Innovation Alliance systematically examines buildings, from the building materials used all the way to the finished housing development. The portfolio also includes the chronological observation of a building covering the entire life of the object. All of these areas represent chances for rationalization and potential optimizations which are to be leveraged and realized. The Building Innovation Alliance creates exactly those synergies in the portfolios offered by the various Fraunhofer institutes involved that make it possible for customers to give their products new value added.
