We are building a super efficient home, as little air leakage as possible. And thats a good thing. However, since the house is sealed tight, you are breathing the same air, over and over again. Similar to being on an airplane, except with out the air purifier. Now this gets even worse when you add the scents and smells of cooking to your already stale air. So the ERV attaches to your HVAC system and when running brings fresh air in from outdoors while removing the stale indoor air. Bringing fresh air in is a great idea, right? Kind of a no brainer. The problem is when the outside temp is really hot or cold. You would be bringing in that extreme temperature air and killing your energy bill.
Wallah. This is what the energy recovery portion does. It has a fancy way of bringing in fresh air without bringing in the extreme climates outside, so that you are not compromising your energy efficient home. So the big question is do I get the ERV installed during construction or take my chances on breathing stale air forever? Advantage Development Co.
