Circularity is not a goal to aim for in itself. Instead, it is a way to make the construction sector more sustainable by focusing on buildings with a higher energy efficiency, while also considering the impact of material use on the environment and the depletion of raw materials. To avoid high circularity having an equally large impact on the environment, we also need to consider the environmental impact of materials and buildings in circular construction.
In a construction project you can intuitively aim for a low environmental impact by making environmentally conscious material choices based on some simple principles.
Or you can go a step further and carry out more in-depth studies using a life cycle analysis (LCA) to make well-considered material choices that reduce the environmental impact of the building.
