You have to build tight and ventilate right. Air leakage needs to be controlled in houses by making wall and attic assemblies as tight as possible. This not only prevents drafts but reduces the amount of airborne noise and dust from entering the building while ensuring that insulated cavities remain moisture-free. With the proper use of exhaust fans and heat/energy recovery ventilators, a building envelope can be made tight while, clean healthy, air is circulated through the structure.
