LEED Core Concepts Guide, Third Edition

According the the USGBC website: "What it is: Looking to learn about LEED and green building, but don't know where to start? The LEED Core Concepts Guide introduces the green building fundamentals to get you started on your learning path. This edition features updates based on LEED v4, the newest version of the LEED green building program. Who it's for: Candidates for the LEED Green Associate professional credential, Anyone interested in a soup to nuts overview of the basics of green building concepts and strategies." Through USGBC the book is $90 (members are $75), I paid over a hundred for this one. I know I am new to the Amazon selling, but I am just a college student trying to sell my school books after being told the school won't buy them back. Please let me know if you have any questions. Sincerely, Michelle
