The project is focused on strengthening SMEs in the building sector because of their great importance as employers in alpine valleys. New developments and changes concerning building techniques of energy saving and producing buildings (ESAP buildings) require cross-sectoral networks and collaborations of SMEs. Because of the increasing complexity in this field there is the need for customers, especially public builders, to have a better basis for decision-making. The key topics of the project are: 1. Providing latest technical know-how for craftsmen and architects; 2. Developing tools for public builders which act as decision guidance; 3. Providing customers with innovative financing tools concerning the energy production of buildings. All in all the craftsmen will be supported in this period of change and the demand for ecological building will be raised. To reach these objectives the PPs form transnational expert groups and their results are implemented in pilot actions.
