percentage of vertical fenestration

I have a doubt concerning the percentage of vertical fenestration I have to consider for Table G3.1 5.c. Let me give you an example. A squared building has four facades, all with the same surfaces. The percentages of vertical fenestration are: - facade 1: 60% - facade 2: 20% - facade 3: 20% - facade 4: 20%. Therefore considering the whole building the percentage of vertical fenestration is 30%. For the baseline model shall the limit of 40% be respected by every facade? Or only by the average value, considering the whole building? Regards
