In simpler times there was only one credential that could be earned from the United States Green Building Council (USGBC), and once merited you were known as a LEED Accredited Professional (LEED AP). There are now two possible designations that can be earned, known as “Green Associate” and “LEED AP+”. The new designations, what they are, who they are meant for and how to earn them can get confusing so I tried to clear it up a little here.
