The "Climate Biennale Pavilion" invites visitors to an open exchange of ideas and to linger. It is a meeting place, a starting point for many of the programme's events and a place for discussion: this is where climate culture is discussed, negotiated and practised. A weatherproof textile roof makes it possible to use the open pavilion even in bad weather for small events (about 100 people) such as discussions or performances. The pavilion is not an enclosed space, but comes into contact with the existing courtyard, embedding itself in the existing vegetation and allowing it to be experienced from a new perspective.

The existing vegetation in the courtyard of KunstHausWien, which runs along the edge of the perimeter walls in planting beds, is complemented and extended by a dense, forest-like underplanting. This densification increases the climatic performance, which enhances the quality of the stay, especially for events in early summer.

The wooden pavilion is a reuse of part of the Climate Culture Pavilion that was built by the Breathe Earth Collective in Graz in 2021. The installation has already successfully provided important impulses for climate culture. The concept of reusing an existing wooden structure plays a key role in the context of a sustainable climate debate.
