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?

NC-2009 MRc4:Recycled Content

Seismic isolation system

Hi, Our project includes seismic isolation system, because the project building is located in earthquake prone country. Our question is which construction division does "seismic isolation system" belong? Can it be categorized as equipment? And can we exclude it from the calculation? Any comment would be greatly appreciated. Thank you.

NC Credits MRc3 through MRc7 all evaluate materials classified by Construction Specification Institute (CSI) MasterFormat under Divisions 03 through 10 and parts of Divisions 31 & 32. However, CSI classifies “Sound, Vibration, and Seismic Control” Systems in Division 13 “Special Construction.” Therefore, you should exclude these materials. [Project teams outside North America may not be familiar with CSI MasterFormat. It is a standard for organizing construction specifications, costs, and related data. A free outline of the current version is available at this link: http://csinet.org/numbersandtitles .]
