Cultural heritage buildings hold a unique niche in the urban landscape, as they embody the local cultural and historic characteristics that define communities. Extending their useful lifespan has multiple benefits that go beyond the project itself to the surrounding area, contributing to sustainable development, but decision-makers lack knowledge of the environmental benefits and tools for adaptive reuse of cultural heritage buildings.

To this end, this article provides a circular economy framework for the adaptive reuse of cultural heritage buildings to reduce environmental impacts. The framework integrates methods and techniques from building and construction literature that aim to reduce lifecycle environmental impact of buildings through a circular product supply chain approach.
