Code question regarding HRVs and bathroom fans
Everything was going well in our green home planning process until a short conference call with our mechanical contractor today.
1. our home will be too dry (we are omitting a humidifier)
2. our bathrooms still need exhaust fans (we are installing an HRV) in order to pass inspection and meet code
3. an HRV should never pull exhaust air from the laundry room as it will create negative pressure
My approach is to ignore #1 as I believe he is wrong as long as we meet our tightness target of 1.5ach. We can resolve #3 by showing him the installation manual. My concern is the code issue that he brings up. Is this true regarding the requirement of bathroom fans? Any suggestions as to where I can find this code information?
I realize the best answer is to find a different contractor but it has been terribly difficult to find any trades familiar with high-performance homes in our area (Detroit, MI).
