LEED is a work in progress. Certainly not perfect. Unfortunately like many things today everyone is trying to figure out how to make money off it or anything sustainable. It will take some time but I think we will get there. I was at a Residential Green Building meeting last night and the people involved truly want to make a difference. The group consisted of builders, modelers, Architects, bankers, and Realtors, all working at the local level to improve the system. Many feel hindered because those involved with USGBC, NAR and others have to tow the policy line even if they disagree with it. What was sad is that I was the only home inspector there. Sooner or later we will need to be involved as an industry because the movement is here to stay. We need to be heard because we are the ones who will have to deal with it down the line. As for green building codes, see if there are any classes offered in your area by your state. In Illinois there were several all day classes offered for free, code books and all. It was part of federal money given to the state. The classes were offered to designers and inspectors. The biggest takeaway I got was that many communities would likely farm out green inspections rather that pay to have their inspectors trained. Illinois adopted the energy code state wide(except Chicago). For now I am trying to navigate the green waters. Like the 70's there is a lot of crap out there, however there are some good products, materials and systems that are sustainable. Sustainability is here to stay.
