What is perfect? What I like about LEED is it has created a benchmark to improve the way we build and operate our buildings in a manner that is less destructive to the environment and provides for improved indoor environmental quality. We are early into the widespread adoption of the sustainable building movement in this country. The Europeans have been doing this (particularly the Germans) for decades and have codified the process. Is there room for improvement in LEED? Yes, of course! But there is a means in place to allow for graduated improvements to the rating systems. At some point I expect the rating system to incorporate a means to vet the actual performance of these buildings. After all, we can't expect to control or improve the outcome if there isn't some form of reliable, unbiased feedback, now can we?

That said, to these people who are so quick to throw stones at the rating systems or at the sustainable building movement: I challenge them to offer real suggestions for improvements to the rating system, keeping in mind it is a voluntary system, and the idea is to encourage widespread adoption of its concepts.
