How would you vent this attic?


Recommended Posts

7500 square foot building with soffit vents around the exterior and one large cupola in the center of the roof with vents on the side of the cupola.

I'm thinking ridge vents would be a better solution.

Your thoughts?

Commercial office building with six bathrooms and one kitchen as moisture sources. I guess it seems to be working okay. It's location within a complex has some architectural requirements for matching other buildings. They're all done the same way.

If it aint broke don't fix it.

For sure. Especially attic/roof ventilation which can confound.

If a system has been in place 10+ yrs and looks nice and dry, but does not meet code or make sense by general building science understanding. So what? Leave it alone.

There'll be no significant cooking or bathing and no laundering. Really no moisture to speak of.

In the picture, it looks like the cupola spans a rated wall in the attic. If so, there might be a concern about fire.
