Whole House Fan style ventilation in attic-less SIP roof home
I’m commissioning a new construction home in the Columbia River Gorge area that I would like to be comfortable without air conditioning. The home will be one story, made of faswall.
In this area we have a very wide diurnal temperature range. For example today the low is 49 and the high is 87. If that natural range can be evened out, it’s very comfortable most of the year without any artificial heat or air conditioning.
I was considering using a traditional attic with a whole house fan to help cool the house at bedtime. The problem is at 10 PM it is nice and cool out but the house might still be retaining a lot of heat from the day. When it’s bed time I want to be able to blast the cool evening air through the house to change the temperature.
My architect would like to consider a SIP roof (no attic of course) with vaulted ceiling, shed or skillian roof line. That rules out the whole house fan.
What I’m wondering is – is there a good alternative to the attic whole house fan that works in the SIP/vaulted ceiling?
For example with a shed/skillion roof one could imagine sticking a large vent fan through a wall on the high side of the building just under the eaves – can that be done? Are there whole house fans designed for wall application? Or other solutions?
Obviously the old “box fan in a window” method works, but doesn’t flow a ton of air and is rather a clunky plan for a new construction home.
