It’s Getting Hot! Climate Change in the City: Symposium



04.11.2021 | 10:00 - 20:00
Architekturzentrum Wien, Museumsplatz 1, 1070 Wien online

"The most climate-friendly house is the house that is never built", as Gerlind Weber likes to say even though she knows that this is not really an option. How, then, can we make building more climate-friendly by design? How can we improve the carbon footprint of existing buildings and existing neighbourhoods? How can a city prepare for climate change, mitigating any negative impact while establishing climate justice? These and other questions will be addressed at this symposium, attended by distinguished experts from around the world.
