The perfect cycle

Recovered paper is recycled six times before it becomes cellulose insulation. And cellulose insulation can be blown-in up to three times. Yet even then the cellulose is far from worthless. In fact, it may still be extremely useful — as a fertiliser for agriculture. Project leader Prof. Dr. med. Konrad Steiner on a pioneering recycling scheme that completes the cycle for the raw material, wood.

Hugely innovative

The architect Simon Speigner implements prototype projects based on the Passive House Standard. An ecological building designed by him became a pilgrimage destination for planners from all over the world. At his office location, he now runs an in-house hydroelectric power plant.

Simon Speigner became an architect — and decided to use wood early on due to his family history. "It was also logical to work with wood because of our focus on ecological construction," he says. Also, it soon became clear that building with Passive House technology would make a lot of sense.

A tradition introduced by Georg Zenz senior 60 years ago, continued by his son, Georg junior, and now today on the threshold to its third generation with Michael Zenz, who last year completed his studies as master of his trade.

Kay Künzel is expert for green architecture

He counts on passive houses and energy-efficient construction and is an approved expert for acoustic and thermal protection. And: Kay Künzel cannot understand the culture of questioning “When does it pay off?“ with regard to house construction. “I don’t ask this question when I buy a pair of pants, either.“
