Construction Loan Questions
I want to use some variation of the geothermal envelope technique. The ways I’ve heard of this being done combine insulating the outside of the house and then either: a) building the entire frame and walls of concrete to “soak up” and radiate the constant 50’s temps from the ground or b) leave the inner portion of the envelope open (forming channel between basement and first floor) and run fans to circulate the mild air.
Small, cheap, and zero energy – what could possibly go wrong?
Check into ICF construction. ICF is an acronym for Insulated Concrete Form. In a nutshell, it is a method of constructing all exterior walls with styrofoam blocks that are then filled with concrete resulting in a sandwich; foam where the ‘bread’ would be, inside and outside; concrete where the ‘pastrami’ (hey, I love pastrami, what can I say?) would be, between the foam. The result is an extremely well built and solid house with a high R value, R-35 walls if memory serves. The exterior and interior are finished with conventional materials so it’s appearance is just like conventional construction. I used drywall inside of course, and outside I used Hardiplank cement siding.
I was persuaded by my draftsman to build my house from ICF and although I had my apprehensions back then, I am so glad I followed through with it.
Hey, as an added bonus, if the S really HTF, I live in a concrete house: easily turned into a bunker!
