I am new to building and live in SD. I want a home with good healthy indoor air quality as I have sensitivity issues. Spray foam is out. I am thinking of using ICF forms for the basement and 1st floor in a ranch style home. Cover the walls with sheet rock and insulate the attic with cellulose. Using a HRV system does anyone know if there would be any off gassing problems with the ICF?

Also, I read something about embodied energy and ICF forms. Can you explain this to me.

Thank you,
