I have been looking at the Energy Star website and I cannot find the criteria for qualifications of the various items for the tax credit.  There is so much crap on the website but it seems to just dance around the info needed to determine if something qualifies.

At one point a few years back, there was a map for windows and doors based on the location installed but I cannot find that now either.  Can anyone point to a handy reference on these items?  Am I just looking in the wrong place?
