The principles of circularity for the sustainable design of buildings aim to reduce their environmental impact. Environmental product declarations (EPD) and carbon footprint tools are the most useful tools for classifying building materials and evaluating circular projects. Other life cycle assessment (LCA) tools are used and coupled with this workflow to evaluate their circularity. Capturing the whole life cycle sustainability of construction projects, this study evaluated a wide range of input design parameters and revealed a correlation between the building materials choices and carbon emissions. It recommends increasing professional knowledge and industry use of LCA to realize circularity in construction.
