I've started a short video series to explain my work in high performance wall systems.Some quick background - my colleague Scott Hedges and I have spent some time studying home building practices in…Continue
"The golf analogy is fine for a general point, pointless for those three criteria.
Valuating energy performance takes data on local energy costs, and an energy rating for the performance of the house, and a baseline for comparison. The rest is simple…"
"I don't disagree with the situation, I disagree about accepting it. Appraisers evaluate based on insightful observations. They lack insight on energy and this needs to be fixed.
Appraiser's need to become more competent - this s what the…"
"Ted, what you just wrote explains why the existing method is broken. You are stating that value rests solely with what is apparent at the surface to an untrained eye, a system based on the lowest common denominator of competency. Appraisers are…"
"My question was about the Bill, yes, described at the Resnet article linked in my original post.
ted, I don't find let the market decide a compelling argument. Do appraisers currently let the market decide? Or do they interfere with the ability…"
"Well, it is referred to as a "Bill" in the article. I don't mean to get into semantics here, but a Bill becomes an Act or a Law when its is approved/signed by all due parties. I'm not sure what you mean when you say it is not…"
"I understand what you are saying - your poles are inboard of the exterior walls, so yes, you don't have temperature gradient across the diameter of the pole, but no, you have a gradient over the length of the pole which at the exterior…"
"Pole foundations are affordable, but I have to wonder if you would have been better off stopping them at the floor. We put so much effort into isolating the thermal bridges created from studs, and here you have these large diameter poles passing…"
"Tom, I think I've clearly agreed with your description. In fact I don't think anybody here has disagreed with that. There is no argument about that, at least not here.
If these facts were enough to convince people to build this way they…"
"David, you mis-understand my posts. You are reacting to my comments about the fictional spray foam.
We do have everything we need to build high performance houses today, and yes they cost somewhat more, and yes energy savings pay for that…"
"If there was such an insulation, it would be expensive - because it was doing something that other insulations could not. And the manufacturer would know it, and they would price it accordingly. That is the way the world works, unless you want to…"
"I find that to be a pretty meager improvement over 40 years.
And Code does not provide for retrofitting of the vast body of existing houses which are the ones using all the energy. Building codes are just not the way to make a difference. You need…"
