Ventilating Stairways in Multifamily Buildings on the Cape
I am renovating a five building development in Orleans, MA that includes a new envelope (windows, added insulation on the exterior and new siding). I am also planning to add fresh air to the small (2 stories) stairwells in each building. Should I be concerned about humidity so much that I add a cooling system as part of the ventilation? There will be continuously running bath fans in each unit and existing through wall AC units. I don’t want to overdesign for a few days a year that I might generate condensation because I am not cooling the make-up air.
Thanks for any help.
