We remodeled to tight envelope + radiant heat but our architect failed to spec fresh air ventilation. We had to DIY it mid remodel and learned a lot in a hurry.
The one room that we didn’t get any fresh air flow to, now stinks. The others are fine.
In a nutshell: blow fresh air into bedrooms / closets. 10 CFM is enough (small cpu fan level of airflow). Exhaust with quiet bathroom fans on constantly at low CFM. In + out = flow. Rooms with no flow = stinky, musty, germ contamination, good for growing mushrooms, bad for people and pets
- pfdietz 4y agoDid you use an ERV?
- chuckledog 4y agoNo, we live in a mild climate so the cost of ERV outweighs the benefit for us. I researched it, but balked at the high price of the unit, and the idea of adding lots of ducting in the attic. Instead went with separate AC Infinity (grow-room) fans each pulling air through a filter. Works ok. Still iterating tbh. This all predates the war. Another factor for us was wildfire smoke
