The increasing cost of traditional energy sources and the availability of new emerging building technologies in lighting, heating, ventilation, air conditioning, isolation, energy monitoring and management of the buildings as well as integrated renewable energy technologies, are expected to increase the global market for low carbon solutions. However, some financial, organizational and social innovation enablers are required to leverage the transformation towards more sustainable buildings and cities. New green performance based business models clearly have to be introduced for stepping up the adoption of new energy efficient solutions through the creation of cooperative and collaborative business networks, which will allow an early involvement of all relevant value chain stakeholders in the energy efficient construction optimization process. This includes e.g. construction SMEs, ESCOs, building owners (private and local authorities), local administrations or financial institutions.
