hey Scott, we are currently working on a LEED project and from our position as a fabricator there really isn't much to it. the general and the architects are the ones crunching all the info and numbers to get the best LEED ratings they can as far as what their goal is. to my knowledge we submit all our info for the materials that will be used and the paint that will be applied and they do the figuring from there, as far as recycled content, VOC's etc. they have many ways to score points in this system and i think all it takes is staying on top of and tracking everything that is recycled or taken to the dump post-construction, among other things. in the west i have noticed a very sizeable wave of green construction, as a fabricator once you get used to it, it's not too big of a deal ( or headache). the extra cost is usually in the owners court. hope it helps.
regards,
JJ
