I am currently looking for a PDF version of LEED rating system CS 2009 updated from october 2010. Current version on USGBC website is updated from 2013, but the project I'm currently working on was registered on an older version.
Valentin, I have the original 2009 version. With that, you could use the LEED addenda database to figure out which updates apply to an Oct 2010 date. Contact me via this website if you want me to send it to you.
