LUNOS fans for whole house ventilation
So I read https://www.greenbuildingadvisor.com/article/ventilation-small-home as well as the couple of podcasts on ventilating a small house. I am working on an 1150 open plan (loft) house and trying to determine ventilation. IRC 2018 requires minimum 30cfm or 45 if 2 bedrooms (am gonna shoot to get it coded as 1 but not sure). When I lookup the LUNOS fans (https://foursevenfive.com/lunos-e2-kit/) it says: “Three flow rate settings of low, medium and high with ventilation rates of 10/15/20 CFM or 9/18/22CFM”
I chatted w their support and they seem to suggest this would work but how? If they work in tandem wouldn’t the pair do 22cfm max? How would I achieve 45?
