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?
