When building a 12 m tall industrial shed with a peaked roof it is desirable that the sides of the shed should stay open as much as possible for ventilation / safety / access concerns.
On the other hand, an entirely open side from top to bottom might cause a lot of rain exposure when the rain comes in angled?
Is there a trade-off possible? Perhaps to enclose sides till a certain distance below the roof edge? Any heuristics about how much? (I've shown 4000 mm in the sketch below)
The contents inside the shed are relatively robust / waterproof & hence absolute rain protection is not needed.
