The Vorarlberg Environmental Association offers support and guidance in the renovation and construction of sustainable public buildings to all communities in the province of Vorarlberg, Austria. The Municipality of Lorüns was supported by the Association’s GPP advisory service in the preparatory, planning, tendering and construction phases of their latest building project. This study focuses on the contract to build a low environmental impact façade for the local fire station. Assistance with concepts for materials, construction and energy, as well as environmental and legal checks was provided. Furthermore, as part of the tendering support service offered, technical specifications were selected from a list of GPP criteria within “Baubook”, an Austrian ecological building product database. This comprehensive resource includes environmental, energy-efficient and free-to-use criteria devised by the Austrian Institute for Building and Ecology (IBO) with input from IFZ and European Institutions. Over 50 projects in the province have used the advisory service to date.
