Erratum – V6.0.0 Checklist A5 – Criterion 15 - KBCN1746

Checklist A5, Criterion 15 incorrectly states, 'The average g-value of the glazing is ≥ 60%.' This should read as follows, 'The average g-value of the glazing is less than (or equal to) 60%' The intent of this criterion is to limit the impacts of overheating. This will be updated in the next reissue of the technical manual.
