HRV ducts in a slab-on-grade bungalow
I am designing a ~2000 sq. ft. slab on grad bungalow home which will hopefully be airtight (below 1 ACH) and very well insulated with grid tied PV (net metering). I am located in Ottawa, Canada which I believe is a climate zone 6A.
Currently I am researching and educating myself regarding various heating (ductless mini split) and HRV option. The dilemma I am running into is not wanting to run the HRV ducts into the attic for the many reason most of you already know. Other than creating a ceiling service cavity below the insulation/air-barrier, are there any other options?
