«Spaceship Earth - repair advice for the crew»: this was the start of the Lab of ideas 2022after the welcoming speeches. Dr. Gregor Hagedorn, Academic Director of the Museum für Naturkunde Berlin and co-founder of Scientists for Future, demanded among others that the topic of climate change should make up 20 percent of teaching at universities in the future. He emphasized the importance of comparing the risks of maintaining the status quo with those of change - such as possible loss of prosperity. There is a need for a paradigm shift, for example, to only sell things that can be recycled or to replace oil heating systems with heat pumps instead of natural gas heating systems. was

Many people do not initially associate the protection of historical monuments with climate protection. But what opportunities do historic buildings offer? Are solar systems allowed to be installed on World Heritage buildings and where is this already happening in Weimar? Susanne Dieckmann, Klassik Stiftung Weimar, Prof. Hans-Rudolf Meier, Heritage Center of the Bauhaus-Universität Weimar, Florian Dossin, Bauhaus-Universität and co-founder of the Institut für Graue Energie and Prof. Eckhardt Kraft, Chair of Biotechnology in Resource Management at the Bauhaus-Universität, discussed these questions. They agreed that monuments should be considered holistically. In addition to energy, their cultural and design value has to be considered. Also, new or renovated buildings could compensate for their energy gaps. Sometimes, solar systems can even usefully complement monuments, as in the Museum Neues Weimar. was
