Re: I'm looking for idea's to make my home energy efficient

All these ideas are great, thank ctyankee and DC.

The house is in SC, almost no one here has a basement, the house sets on brick piers. The foundation is sound. The house has not had a coat of paint on the outside in over 70 years, it natural wood color. It will probable take a thousand gallons of paint to get a good coat. I like the info on insulation, it included information on INSULADD insulating paint and foam might work in the walls.  The floors are not hardwood, they are heart pine planks. The whole house is heart pine.

What is FSC wood? As for the windows, I plan on replacing them when I find a supplier that makes windows that match in appearance. The roof needs replacing and insulation installed there also. The original roof is of 2x4 construction with lathes and wood shingles. We see almost no snow here, the roof has lasted over 100 years. I don't want a metal roof!!

PS:  I'll be doing most of the renovation myself, sub-contracting only the things I can't or won't do, like the roof.
