Sucking in CO2 and building houses from it - is that possible?

Today we build mainly with concrete. But it is concrete that has a lot to offer: according to the latest estimates cement production accounts for eight percent of global CO2 emissions. That is no small matter! Moreover, sand and gravel are not infinitely available.

Wouldn't it be practical if we could suck up the CO2 and use it to build houses? That would be finally a good and convenient solution in the fight against climate change!

What seems like a far distant, unrealistic future scenario has been practiced for centuries: With wooden construction! The CO2, which a tree extracts from the atmosphere for its growth, remains bound in the wood used. The more wood is used, the more the more timber is used, the more timber construction actively contributes to the CO2 sink.

In the context of a at the Bau+Energie trade fair in Bern, we will be looking into the question of what timber construction can climate protection, what is possible in timber construction and where the limits are. are.
