LEED CI in a LEED NC building-overlapping credits

CI-2009 WEc1: Water Use Reduction
posted by Leslie Jones on Jan 12, 2011, 10:38 am

Leslie, in most cases LEED-CI credits are designed to be more specify and not overlapping with NC-type requirements. For example, WEp1 only applies to fixtures in the tenant scope. Also, EAp2 requirements are very different for CI. With things like bike storage you do need to make sure you're not double-counting something that another CI project may be counting.I hope this answers your question. More specfiic questions may come up, and be best addressed, the specific CI credit pages and forums. Log in or register to post comments 4 Vote up! ...

posted by Keelan Kaiser on Jan 18, 2011, 1:34 pm

In 2007 Schools, can we apply for two ID points if we get our on-site renewable production up to 22.5% (12.5% + 5% + 5%)? 25.5%? This seems like a possibility if I read correctly the limit of up...
