Wood construction for any environment on earth

Exhibition of the first construction element technology in the world harnessing vacuum drying phenomenon as a maintenance service.

The Vacuum Insulation System (VIS) is a novel wood construction technology that has great potential to play a major role in the future of carbon neutral construction. In addition, VIS paves a way to combine wood construction and vertical farming to cut down the constructional CO2 emissions of urban food production of the future.

VIS technology relieves the possible moisture problems inside a wood construction element that may stay invisible for years or even decades, leading to structural weakening of wood and indoor air quality problems. The inventive step demonstrates the possibility to remove unwanted extra moisture onsite before the biodegradation process kicks in without the need for demolishing any structures or replacing materials.

Anything but an ordinary greenhouse

A wood-structured windowless greenhouse consumes only half as much energy as a traditional glass greenhouse. In addition to producing food, Pasi Herranen’s invention could generate electricity and excess heat in the future.
