NC-2009 MRc4: Recycled Content
Has anyone used this new materials and resources calculator uploaded to USGBC site in Jan 2016 for LEED v3? I am unclear on the regional materials - there doesn't seem to be a designation for where you put the mileage for harvested and manufactured locations. Let me know your thoughts, or what I am missing.

The recycled content percentage on the product data sheet is given as a range. What should I do?
Is the default average recycled content value of 25% for steel still allowed?
Can site materials, such as soil, be included in the MR credit calculations?
Are there recycled content claims that I should be wary of?

Patricia—We have been trying to get clarification from USGBC. See this comment string from the NC-2009 MRc5 page: http://www.leeduser.com/comment/redirect/61864.

I would also like clarification. Seems like an error made by the USGBC.

Just as an update: On April 8, 2016, USGBC issued a revised version of the Materials and Resources Calculator (v07). For now, at least, you can download this spreadsheet from the same link that Patricia posted above. There appear to have been some modifications to the instructions, but I suspect that v07 does not resolve all the issues that Patricia raised concerning v06.
LEEDuser has a new forum, “LEED Online Status Updates” (http://www.leeduser.com/strategy/leed-online-status-updates) to address issues with the latest LEED Online forms and calculators. There, Michelle Reott is working with USGBC to answer or resolve issues with the new tools. Check in to the new forum for the latest news.

Patricia, Steven, and Jon - I was asked to review the latest Materials and Resources Calculator v08. It should be released with (or before) the 1/1/2017 quarterly LEED Addenda Update. It will be cataloged as a Form Update (under Entry Type) in the Addenda Database - http://www.usgbc.org/leed-interpretations.
Keep an eye on http://www.usgbc.org/resources/materials-and-resources-calculator-v2009 for the new version.
One of the fixes was to rename the dropdowns in Column S to differentiate between BD+C and the further clarify the two options in ID+C. Column S was also renamed to make things clearer. “BD+C” was added to cell T7 to make it clearer this is the Distance for BD+C and ID+C projects. And the embedded comment in cell T7 has been updated to reflect that for BD+C only the furthest of the compliant manufacturing/extraction distances is to be entered. At least this method of entering the furthest compliant distance can be used and you’ll be on the same page when the updated version is released.
