I recently received an email from Bob Blanchard, who consults with home and commercial building owners to achieve and maintain healthy indoor environmental conditions. Bob explained that in our very humid climate, keeping closet and bedroom doors closed (something many of us do thinking we’re saving energy) could actually be detrimental to indoor air quality.
Mr. Blanchard explained it like this: keeping spare room and closet doors closed could and likely will result in mold occurring from condensation, usually on shoes and around the supply grill. The lack of air exchange in those closets from the closed doors allows high indoor moisture levels, particularly in the high humidity of spring, summer and fall weather the South experiences. Stagnant moist air with little ventilation is a breeding ground for mold. Tune in tomorrow when we’ll discuss steps to take to improve indoor air quality.
