Energy efficiency - in a nutshell
Nature as a valuable
no thank you!
100 percent ecological & naturally health friendly
We were the first German construction company to be certified with the eco audit as early as the 90s.
Our 37 cm thick complete-solution wall is composed almost entirely of the natural material wood and reduces the annual energy consumption dramatically.
Our patented wood shavings insulation is the world's first cradle-to-cradle certified sustainable natural insulation.
We developed HOIZ, a wood shavings insulation, made from scrap wood.
Our minute accuracy, not chemicals - together with triple glazed aluminium wood clad windows guarantee perfect thermal insulation.
With the most innovative and intelligent domestic ventilation technology all natural energy resources are utilised perfectly.
The result: lowest energy consumption and enormous reduction in CO2 emissions.
