There are limited available datasets on building materials as they are typically not transparent, and research is usually done to individual materials or components.
Unfortunately, construction activities consume as much as 40% of global energy and materials used, emitting about 35% of carbon dioxide [20] using 30% raw materials and 28% of landfill material as construction debris [6].
Although less toxic and safer materials such as sustainable and green building materials are available, they are not widely used.
