My project is removing asbestos that is included in a wall system and replacing the gypsum board but retaining the structural system beneath it. For this credit, can I exclude the initial areas of the asbestos contained walls as part of my denominator value? I could have sworn I saw a CIR about this a while back but can't put my finger on it.

I've seen the same information. Here's what LEED HC says: "Hazardous materials that are remediated as part of the project scope shall be excluded from the calculation of the percentage maintained." CIR/LI 5583 from 8/2002 also allows you to exclude from MRc2 calcs. Have you searched the Reference Guide addenda?

Thanks Susan. That's my sense too. I've looked through some of the addenda but may have missed it?

I did a quick search through the new LEED Interpretations and did not find it either. But the search should have popped up the LEED HC item and did not. Clearly I need more search practice.

Trying to bring this back into the forum discsusion again. Anyone know where I can reference as verification that my approach is acceptable?

Guidance from the GBCI confirming this approach:
“Although it is not specifically stated in any reference guide, addenda, or LEED Interpretation (CIR) for MRc1.2 in ID+C or BD+C, GBCI confirms that projects should exclude the hazardous materials completely from the calculation for this CI credit – both numerator and denominator. This is assumed through the guidance found in MRc1.1 (pg. 347 in the BD+C reference guide) which states, "Hazardous materials that are remediated as a part of the project must be excluded from the calculation of the percentage maintained," even though it is technically a separate but related credit. Also, it is discussed through LI# 5885 from 9/19/2005, even though this is not directly applicable to 2009 projects or CI projects at this time.”
