Hello all and please excuse for not posting in German.
I have a design in progress which is an energy building hosting many electrical equipment. The structure has one expansion joint by design, which doubles the columns. There is one compartmentation wall between one set of columns. The roof level is different for the two building parts.
Do you believe is it necessary to add an extra wall at the other part of the joint, so as to avoid a risk of rainwater pouring in and possibly damaging the equipment?
