ERV, HRV or whole house dehumidifier
We are in the process of building a new home. The location is outside Seattle, WA, Marine 4C, where the average humidity is 76 %. In a well-insulated home (2×8 advanced frame with blown cellulose and Zip-R sheathing R-6 exterior ) with <1.5ach50 would it make sense to install an ERV, HRV or whole house dehumidifier? Conditioned space is @3,200 sqft with a full basement w/ R-10 sub slab insulation and walls constructed with ICF’s, @ R-22. Heating is radiant flooring.
