Coffee roastery Joh. Johannson

Vestby, Norway

Joh. Johannson Coffee is Norway's leading coffee roasting company. With an annual production of 12,000 tons of coffee, the company covers approximately 35 % of all coffee drunk in Norway. The energy consumption of the new coffee distillery is covered 100 % by renewable energy, emitting 85 % less CO2 than the old production. By means of solar panels which are part of the building facade and by recovery from the heat of the roasting process, more energy is provided than the production itself needs. In terms of coffee processing, Joh. Johannson Coffee is probably the most advanced and eco-friendly plant in the world.

KIELSTEG, a self-supporting and load-bearing structural element primarily used for roof and ceiling structures in building construction, made it possible to realize the coffee roasting plant's wide-span yet slim structures. The 6,780 m² roof structure made of KIELSTEG elements allows for high load-bearing reserves of the building even in winter.

Architect Astrup og Hellern, who was commissioned with the planning, points to the high flexibility of use of the facility, which allows for future expansions and changes in production and energy generation without having to be converted and leaving the architectural appearance of the structure unchanged.
