Innovative Refurbishment of Single Family Houses. Evaluation of best-practice models and recommendations to support dissemination

The highest need for thermal refurbishment in Austria is assigned to the sector of one-family houses built between 1945 and 1980. According to estimations two-thirds of all possible investments should be dedicated to this sector. However, there are only few successful refurbishment models offered which combine efficiency, comprehensive information, mobilisation, feasibility and are technically up to standards. This study focuses on two of these network models: the Ökomodell Außerfern in Tirol and the network Traumhaus Althaus in Vorarlberg. These models are characterised by intersectional network structures constituted by heterogeneous local social actors they guarantee quality and are attractive for owners of homes.
In this project a comprehensive description of both models is given and functional aspects are analysed. Suggestions for the improvement and the transfer of models to other regions are discussed. The results of this project should help to improve activities on the supply-side in general.
Centrally co-ordinated units manage both network models. In addition to the management of networks these units are responsible for several other functions: Public relations, training courses, strategic development, advisory service for end users, and implementation of refurbishment measures. The subsidy systems of federal states are also of vital importance for the success of the studied network models. The large size of networks did not yet produce the expected high quality standard, this remains problematic. More over, co-operations of network partners in joint refurbishment projects are still seldom.
In order to support the transfer of regionally successful models it is important not only to study the specific conditions of the emergence of the examples but to gain general knowledge about the development and stabilisation of entrepreneurial networks.
