Answer: Cost
If the house is made airtight and control airflow is allowed (i.e. ERV or HRV) then heating and cooling the space becomes quite easy.

There would be very few houses that rely 100% on solar passive design - i.e. they have no heating or cooling in the house. It could be achieved in most…

I agree that in terms of a passive solar the current design does not work well. And I agree NW is not a good orientation. I also am not a…

Fair enough - your choice. Sorry I can't help you with the cost of the install.
I will just say this in passing - for splits if your only issue is…
Bruce123 posted:Installing Ducted Air
Consider multi-head split RC AC instead of ducted. More efficient. They would be easier and neater to be installed during the build. Don't know about the cost difference.
Bruce123 posted:Replacing Splits with Ducted AC?
My opinion - splits are more efficient. The main reason is that with ducted there are heat/cooling losses from the ducts which goes straight into the ceiling cavity - lowering…
