This paper is based on the Master’s thesis of Haitham Abu-Ghaida, which was supervised by Prof. Aliakbar Kamari. The paper was presented at the CIB W78 - LDAC 2021 conference. The paper proposes a bottom-up material mapping approach, ensuring fast and accurate mapping of the materials. A tool will be developed in collaboration with two Danish sustainability consultants in architecture and engineering, and is empirically evaluated on a large Danish housing project in Aarhus, Denmark.
