Innovative Smart Wood Structures

23m spans even allowing for scandinavian snow

11. February 2019

Our Scandinavian partner Control AS has completed a project using Kielsteg for the roof of a CO2-certified supermarket. The Kiwi supermarket chain, which has 650 stores in Norway, has opened a new shop in Skollenborg, a town about 90 km south-west of Oslo. The company has set itself the goal of operating as sustainably as possible: for this reason 70% of the products sold are from Norway and the building materials are CO2 certified. The Kiwi store won the architecture prize. The jury commended the clear architecture, the accessibility features for vision-impaired people and the easy-to-navigate organization of the shop, and highlighted the significantly reduced CO2 footprint of the whole project. The building is constructed to passive standard. The Kielsteg roof covers an area of 1300 m² and has clear spans of 23 m while remaining strong enough to withstand Scandinavian snow loads. The CO2 reductions were partly achieved by insisting on materials that were produced with lower-than-normal CO2 emissions – including the concrete, insulation material, steel and asphalt. Kiwi’s head of store development, Jan Eilif Johansen, says the prize shows that their design is well accepted by the market. The way this store was built applied new knowledge to achieve even better functional and environmental benefits. As the chain with the most stores in Norway, the company sees its role as setting an example of how to deal with people and the environment responsibly.
