For Option 1, BRE Global verifies the LCA tool’s score within the Mat 01 calculator based on the rigour of the life cycle assessment tool and the extent it is used on the assessment. For this reason, as opposed to the UK New Construction schemes, the performance/scoring of building elements is not to be taken into consideration and Green Guide ratings for building elements are not linked to the scoring of the Mat 01 tool and credits achieved.
Please see KBCN0237 for further details on using the calculator with verified LCA tools.
