When is an HRV necessary?
I'm building a ranch home in northern Idaho with a walk out basement. There will be some crawl space areas at one end of the house. I intend to seal them from the exterior so it is conditioned space. The main roof will have scissor trusses with spray foam under the roof deck so the space in the middle of the scissor trusses will also be a conditioned space.
Trying to get as airtight a house as possible, I would think that an HRV system will be highly recommended or even required. I am not very familiar with these systems.
Will the truss and crawl conditioned spaces also need to be factored into this system?
