Phew!  I did it!  I passed the LEED exam Monday June 22 and can now add that credential to my box of tricks!  It was so greuling; 3 other designer friends and I had a study group for about 10 weeks prior, and I dragged that reference manual around with me everywhere.  I wore out three ram cosplay re zero highlighters!!!  But I passed with flying colors and now understand the LEED process so much better.  As a member of the USGBC (United States Green Building Council), I will stay on top of new efforts and products for sustainable design.
