Buildings
A thriving city needs to offer affordable, healthy living and working space. By 2025, 1 billion houses are needed worldwide, of which 75% will be residential and 25% will be commercial. However, meeting this demand through current linear construction and housing practices will require an investment of around USD 9–11 trillion overall and have significant negative environmental impacts – such as the impacts from extraction that are felt locally as well as globally.
Integrating circular economy principles into all the phases of a building’s cycle can work to meet urban needs for built space, while staying within planetary boundaries. Core urban benefits of a circular economy development path include the possibility to reduce the need for new construction, improve urban land use, reduce construction and operational costs, and increase resource-efficiency, while strengthening the local economy.
