Werner Sobek’s “Triple Zero” Homes
German architect and engineer, Werner Sobek has coined a phrase and correlating concept for homes that produce more energy than they use, “triple zero.” The buildings are made of recyclable materials, produce zero emissions and consume zero energy.
The building industry is responsible for a huge amount of the world’s waste and energy use, so by following some of Sobek’s principles and building these types of structures we could significantly reduce our environmental footprint.
To achieve these “triple zero” houses, Sobek drastically reduces the amount of steel and concrete used. He has developed a technique to halve the amount of concrete needed by putting bubbles into the concrete mixture. To maximize recycling potential, Sobek uses stainless steel bolts instead of glue. Glue renders the materials un-recyclable, whereas bolts can simply be taken off with a wrench. The R128, seen above has solar panels on the roof and uses triple-glazed glass to maximize energy efficiency.
