Zero Carbon Building Element

intelligent design - smart construction

Pitch

The zero carbon building element is the key component of a comprehensive approach to sustainable construction. The prefab wall, platform and rooftop modules are made of timber, straw, clay and flax. The concept is trimmed to minimize energy consumption, create a healthy indoor climate and inspire a sufficient lifestyle.

The complex physical, structural and ecological requirements are achieved through a highly efficient but still elementary assembly: Straw bales are slided into a double T timber frame and sealed with clay on the level of the flanges, heat exchangers being able to be integrated in the clay layers. On the inside, a flax fleece is glued on the clay and the wooden parts to form a vapour barrier and a plaster base to be finished with clay plaster. On the outside, a wood fibre board protects the construction. It can be plastered or covered with rear ventilated claddings.
