I am building a grout filled CMU house in the Ozarks. I have limited funds at this point and so I would like to focus my budget on thermal control where it will be needed most (i.e. heating / cooling). So far, I will have a large East facing deck roof which provides an 8' "overhang", and a 3 foot overhang around the other elevations. The west facing elevation gets a lot of tree shade around 4pm. I'll be using engineered trusses with a 10 inch heel for plenty of insulation in the ceiling. The steel roof will be painted white. For heating, I will have a good cast iron wood burning stove with an unlimited supply of free hardwood seasoned logs. All doors and windows will be tightly sealed. Rooms will have adjustable vents (to outside) that can be shut as needed. The house is 51 feet N to S and 26 feet E to W ... and the floor is concrete as well.
At this point I am not sure what to expect. Are the winter nights going to be the challenge or the hot summer days? .. in other words .. should I expect it to be harder to cool than to heat or vice versa? As long as I know which is tougher, then I can focus more energy and budget there.
