By building according to circular principles, we build with less primary raw materials and we allow raw materials to circulate in cycles. High-quality reuse, recycling and circular design are the keys to this.
A linear design process proceeds chronologically: from idea to detailed design, after which it is built. After delivery, the phase of management and maintenance follows. In a circular design strategy, we think the other way around: from end to beginning. At the beginning, we think about how all the materials in an object can be reused. Our policy is to make circular design principles a standard part of our work.
The materials passport
One of the instruments that is indispensable for circular construction is the materials passport. A materials passport records which materials are in an object and where, as well as the quantity and value of the materials. A good materials passport also records maintenance and dismantling information. By 2025, we want 80% of our projects to have a materials passport with a circularity score. Such a score shows how circular objects are and provides information about whether and how objects can be dismantled again.
