BauZ! 2027 is the 2027 edition of the Vienna Congress for Sustainable Building, an international specialist congress and industry networking event that has been held since 2004. It is organised by IBO, the Austrian Institute for Healthy and Ecological Building, based in Vienna. The congress aims to present practical technical solutions and emerging approaches in sustainable construction, and to encourage the exchange of examples and ideas among professionals. 3
The 2027 congress is scheduled for 15–17 March in Vienna. Its call for papers, titled “Newer than new! The existing building as a starting asset and development partner,” frames existing buildings as resources for transformation and reuse, rather than simply as renovation liabilities. 11
The programme’s themes span the building and its wider setting. Topics include shared neighbourhood resources—such as green space, energy communities and shared facilities—and the relationships between residents, owners, planners and project developers. The call also addresses climate-resilient design, including building surroundings, roofs and façades, as well as building operation through natural ventilation, thermal comfort and energy systems. Circular construction is another focus, with attention to reuse, recoverable materials and planning around salvaged components. 2
BauZ! is aimed at architects, planners, engineers, technical consultants, researchers and universities, public authorities, civil-society organisations, industry representatives, manufacturers and facility-management professionals. The congress combines presentations and discussions with specialist workshops and sessions on research and new initiatives; its working languages are German and English, with simultaneous interpretation. 3
