I bet HVAC lobbyists want it, so home owners will spend thousands in new equipment. This is about making money. Your governor wants energy information; not audits themselves. You have to read the fine print. Often, vendors/lobbyists lead you off the trail, so they can make money for the companies they represent. That is what is wrong in most states, and at the federal level. It’s the money, not the people.
I bet tradesmen of all types and home builders are also not licensed in your state, right? So how can they “properly” make the repairs? Lawmakers are clueless, except here in Kansas, where the governor stopped our HI laws recently.
You cannot accurately tell anyone how much energy is used in a home, without utility information and fees, which seem to change daily. If you state a “potential”, and that home owner does not reach that “potential” even when he did what you suggested, there could be a problem. Providing the NACHI articles on energy savings is often enough, then let the buyer decide; not you, IMO.
