Loretta asks: Perhaps this questions is bit too broad, but what is the simplest way to understand how MR1.2-MR 7 work between each other? I understand the no double dipping theory but the rest......

I find myself rather frustrated that there's no simple chart that clarifies this graphically. I thiink I understand, then hit a question which shows I'm totally incorrect on. I have a CI exam coming up and I'm stressed.

Thanks!

Answer: Hi Loretta, one way to think about the MR credits in LEED CI 2.0 is to remember that the first four MR Credits after 1.2 (i.e. MR 1.2, 1.3, 2.1, 2.2, 3.1, 3.2 and 3.3) are all focused on REUSE of materials and building. Whereas everything after that (i.e. MRc4.1- MRc7) is new stuff that's not on site already.

In terms of "value" for LEED purposes, the LATTER items (i.e. all the new stuff) is all measured as if you went out and had to buy it new for fair market value. The FORMER items are all measured individually in different ways... for instance, MRc1.2 and MRc1.3 are measured in terms of area or square feet. MRc2.1 and MRc2.2 are measured by weight in pounds (or cubic feet). MRc3.1, MRc3.2 and MRc3.3 are measured in terms of their replacement value in dollars.

Hope this helps!
