Insulating a house with straw – the straw bale passive house in Böheimkirchen shows how well this works. The EU-funded project was developed by GrAT as part of a research project and completed in 2005. Since then, the S-haus has been used for exhibition purposes and as an office building for research activities.
Renewable raw materials were used for the construction — this reduces the resource consumption of fossil and mineral materials.
Compared to a conventional building, the energy consumption is reduced to about one tenth.
It is the same with the wall construction: While the production of the straw wall causes an ecological footprint of only 2364 (m2a/m2 wall), the comparable conventional wall construction with 24915 (m2a/m2 wall) consumes more than 10 times as much natural land. Read more in our immoflash report!
