FAQs about MRc4 :

I have recycled content information for a product, but it doesn’t specify whether it is pre-consumer or post-consumer. What should I do?

The recycled content percentage on the product data sheet is given as a range. What should I do?

The manufacturer can't give me product-specific recycled content data, but they say that they fall within the national industry average. Can I use that?

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?

Can I count FSC-certified MDF toward both MRc4 and MRc7?

If I have one cut sheet that meets the LEED 2009 requirement to upload 20% of cut sheets by cost, for this credit, is that acceptable?

Can the 25% default recycled content value for steel be applied to door hardware and non-structural steel framing, or can it only be applied to structural steel? Door hardware is my primary concern here. Thanks!

Steve, This is an interesting question and made me look at the reference guide a little closer. I would say yes, you can take the default 25% default for steel in door hardware. I have to admit, at first I was pretty negative on the idea. Then I found this statement on page 373 of the LEED Reference Guide for BD+C version 2009. Under Calculating Assembly Recycled Content - "For example, a pound of steel in a window assembbly is of equal significance in determining recycled content as a pound of fabric on a movable wall panel." Hope this helps and gluck (good luck).

Thanks John, I've been looking at this as well and apparently you can take the 25% default for door hardware.
