ETC Bygg is changing the construction of apartment buildings to climate-positive ones in Sweden.
The houses are almost entirely built from sustainably produced wooden building elements and also contain innovative solutions such as wood-based panels in bathrooms instead of tiles, and kitchens built from recycled materials. In addition, tenants have the possibility to cultivate their own vegetables in their balconies.
These rental houses are equipped with solar panels, which produced more electricity required for operating the houses. furthermore, tenants are able to charge their El-cars using onsite El-stations.
The construction of these houses is financed in an innovative way, through crowdfunding. Private people have been able to buy B-shares in ETC bygg with a guaranteed interest rate of approximately 2 percent per year. So far, 784 people have bought B-shares worth SEK 80 million, which financed the construction of similar rental houses in Västerås and now is mortgaged to build in Växjö.
Resources needed
120 million Swedish crowns
Evidence of success
The houses are built using a flexible system that is already adapted to different cities Västerås and Malmö. Materials, such as plastic, concrete, and plaster are avoided in the production of these houses. A combination of solar panels, battery storage, and mechanical ventilation with a heat recovery system creates low-energy rental houses. These houses are self-sufficient in solar energy all year round.
Potential for learning or transfer
The rental houses
-are almost entirely constructed with wood and recycled materials, thereby contributing to the achievement of the national and regional targets,
-are supported by solar panels to reduce the houses' dependence on the grid,
-are financed in an innovative way.
