Compatibility with health and the environment, material definition, recyclability, indoor air quality and diversity are a few of the parameters of increasing relevance in future planning and construction. But because building life cycles generally exceed those of ‘regular’ consumer goods many times over, the disposal and recyclability of used building materials receive much less consideration. Moreover, the service life of individual components within a building is very different. As a result, the issues surrounding building sustainability are very complex and go far beyond simply seeking to achieve energy efficiency. Eco-efficiency must therefore be an integral part of the planning strategy when designing a building. Eco-efficiency stands for goals such as greater impact, more living space, greater biodiversity, more fresh air, more beauty, intelligent rooms and greater enjoyment.
From there we define the underlying intentions:
The closed circuit pavilion addresses these issues directly. It is a temporary room installation designed for use during Climate Week in Hamburg. It is composed of naturally grown support structures connected to a room framework based on SimpleTec, which is then cut into shape. The branches function simultaneously as the load-bearing structure and the spatial shell.
Pruning trees in Hamburg is part of a local raw material cycle that shreds the cuttings and returns them to the forest floor. The installation uses these cuttings to form the shell in combination with biodegradable load-bearing supports, and then dismantles, shreds and returns it to the soil of the forest as fertiliser after Hamburg Climate Week. DESSO carpet tiles are used for the pavilion’s flooring. They are composed of defined synthetic fibres and carpet backings. After their use, they are removed and taken into the technosphere.
