Various innovative topics were presented at the conference, including Austrian-Chinese research activities on ultra-low-carbon buildings, which focus on daylight utilization, shading, and building-integrated photovoltaics (BIPV). The experiences and results of the “Prefab.Facade” project were also discussed, with a focus on the efficiency of prefabricated facade elements. Furthermore, the approach to climate-positive, circular timber-frame construction was presented as a pragmatic experiment to promote sustainability in the construction industry. The comprehensive renovation of the European Patent Office in Vienna was discussed, with a focus on the architectural, energy, and climate protection concepts. Additionally, the renovation of the Energie 360° office building showcased solutions for a comprehensive energy concept featuring a photovoltaic façade and fire protection. The Balkonsolar Berresgasse project, which integrates PV into social housing, as well as the guide and web tool from the German “SolarEnvelopeCenter” project, were also presented online. Finally, concepts for large PV facades—designed to be both aesthetically pleasing and cost-effective—were discussed, along with the representation of facade structures in digital models to promote modern planning methods.
