If the building’s net internal area is ≥50% either office, retail or industrial (see Mat 01 specific note ‘Mixed use buildings’ in the technical manual) then that use type shall be selected in the Mat 01/02 Results Submission Tool. A building LCA tool may then be selected for comparison with the BREEAM benchmark.
If the building’s net internal area is <50% either office, retail or industrial then ‘mixed-use’ shall be selected as the building type in the Mat 01/02 Results Submission Tool. Then no building LCA tool can be selected for comparison with the BREEAM benchmark – only options appraisal can be done (with no penalty in the credits available).
