Hi, I guess your query relates to the approved "tools" that are shown in the MAT01calculator. Those aren`t fully-flexible LCA software tools like openLCA, but constrained calculation tools that have databases of LCA data or LCA-derived indicators for different materials loaded into them. So normally you input the quanities of materials in the building, and you get in return an "LCA" of your building as designed. We couldn`t get approval of openLCA as it is for this as far as I understand BREEAM`s thinking.
