You end up working for contractors and from my experience they don’t want to pay much.
I am sitting here with IR Camera stuff all over my desk for weeks trying to make the numbers work. I don’t think all that other stuff will make matters any better!
I have had extensive conversation with the HERS group (all the way up to the EPA) last month, the process conflicts with numerous construction standards in place and because Energy-star standards supersedes the “old way” of doing things, there may be major structural failure in the future for these houses. Like EIFFS, the theory sounds good but the standard is lacking. When you seal up a house too much, your going to have issues unless you use all the (expensive) appliances available. I wouldn’t want to be on that end of a class action suit!
You will also find that Energy-star standards are not the same regionally. Everyone does it different.
As you said, you need to start something different. HERS raters around here have a huge service area. They are large companies, of which you may have a hard time competing with. The rating service is often “in conjunction with” another service.
I guess someone has to do it. But, I don’t think it will be Home Inspectors.
How much per inspection, and how many inspections per yr. did you figure on? Can Raters inspect their own construction?
