The ecological impact of construction

People often ask, why reconstructability matters. 

In a nutshell: Because construction produces far more waste and consumes more energy as we think.

We should aim to reuse material and reduce the usage of concrete

Some key factors of the construction industry

For some reason unknown most of us ignore that the construction industry

    • produces more 1/3 of the waste
    • consumes about 1/3 of energy and raw materials
    • creates about 1/3 the CO2 emissions – more then the whole aviation industry

In industrialized countries the percentage is much higher – up to 84%, as you can read in the waste report of the Swiss government

Some key factors for the bad ecological balance

The ecological problem in construction has 2 major aspects:

    • The industry only thinks about building a house forever. Although more and more houses get demolished early, no major player has a sustainable concept how to disassemble a house and reuse its parts. 
    • the industry is limiting itself mostly on concrete and steel construction. As concrete is the biggest contributor to waste and pollution, the missing alternatives are fatal for the bad ecological balance of the industry

Ways to improve the ecological balance of building

Circle economy – reuse material in the construction industry

Reusing construction material is a key factor to improve sustainability in the building industry.

We designed the Reconstructable House from scratch with the idea in mind to disassemble all parts easily from hand without demolition. Like this we can save energy during production, assembly and disassembly and maximize reuse. 

That's what is needed to build a reconstructable house: A box of 2 tons
That’s what you need to build a reconstructable house: A box of 2 tons. 1 leight weight transport, no building machine

Reduce the usage of concrete

The second key factor is the replacement of concrete with an engineering solution that provides a similar stability. The reconstructable house uses regenerative resources like wood which have a better ecological foot print. The speciality of its construction is to reinforce the critical zones and connections with thin layers of steel and other materials. This makes the construction very light and robust.
