When you read that LEED book, you'll realize how much BS is in it.
The USBGC is a "for-profit" organization, i.e it is in business to make money, not to save the planet.
Their have a $350.00 test (highway robbery) for a one hour electronic test, just like a driver's license test, after which you get usually a PASS.
I know marketing folks who have no clue about architecture or engineering that are LEED accredited professionals.
It is chic to be LEED amongst non-engineers, amomgst regular folks, but LEED-AP has no value in the engineering community in my opinion.
The other higway robbery is the fees they charge for membership and for certification.
Unfortunately, Architects have put a lot value in it, so this thing gets recognition.
