Natrium is certified in the highest ranking according to Swedish Building Council. There is a solid work from all parties involved behind the certification. For example, the façade and windows are designed to reduce energy losses and heat radiation. During the construction period, great focus was placed on choosing sustainable building materials and, where possible, also locally produced, for example, the steel reinforcement in the house comes from Norway.
On the roof there are 750 sqm of solar cells which, together with demand-controlled ventilation and lighting, provide reduced electricity consumption.
