Airtight Home Ventilation: Where to Place ERV Exhaust and Supply Grilles

Corbett Lunsford

I only recommend ERVs for very airtight homes (less than 2 ACH50), and in those cases balanced ventilation is the ONLY way to exhaust from bathrooms. More coming on that for those who are scratching their heads. If you DO need an ERV or HRV (hear the difference at https://www.youtube.com/watch?v=QOe4lluGwCg) then where do you put the supply and exhaust ports? How many CFM should they each push and pull? Here's my simple breakdown of what you'll need to consider.

5 Kinds of Ventilation for HOMEChem Control

Corbett Lunsford

Ventilation is simple in concept- it moves bad air out and good air in. But the applications can be intensely confusing- Grace and Corbett help peel the onion of controlling home performance dynamics (and the HOMEChem issues we're learning more and more about) using fans and controls available around the world.

Featured systems are AirCycler, Fantech, Broan-Nutone, RenewAire and Ultra-Aire.
