Industrial shed design...side walls opening for wind flow

I am designing an industrial shed. Can I enclose the shed all from the four sides up to the lowest purlin. I have analyzed this shed on staad.pro and its OK as per ASD design methodology under wind loads.
I have heard that it is important to give gap in side walls corrugated sheets for free movement of wind. Should i go for this design if STAAD is giving okay or i should go for side walls openings?

or should i go for design below having side walls openings
