This is a good question. I think today, especially with federal government requirements trickling down to local government and into the private sector, I think LEED qualifications are becoming a necessity. Not they we are being paid more for the recognition, but because NOT having it becomes a barrier. I am not yet certified in LEED, but I have been on several federal projects where I was part of the team. Because competition for projects is becoming more tough, LEED certified teams are winning the projects over those that are not fully certified, in my experience.
