Can you please tell me if an air exchanger is a must?
In a home being built to Energy Star requirements/certification and will have foam insulation in the attic and blown fiberglass elsewhere (Spiderfiber). The homeowner is trying to cut costs in both building materials and on going operation cost of the air-exchanger. If they open windows on a regular basis would that suffice?
Thank you
