FAQs about MRc4 :

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?

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?

Hi everyone!! Thanks for all the support in my preovious question

So.. I am working on three different projects. I am wondering now, which material calculators should I use for each?

These are their charecteristics:

1- NC v2009, registered on Nov 2011

2- CS v2009, registered on Aug 2016

3- Campus: v2009, registered on Oct 2016

Is there a link where I can see that? Can I use the same one for the three?

In case I can use any, is there one you recommend?

Thanks a lot!!

You can use the same version for all 3 projects. It's usually best to use the newest version available, as they often work out issues within the file with each release. I have many projects that have kept with the version that was available when it started b/c they already put all the effort in to populate, and don't have the budget/time to migrate the info; I have many others that are able to migrate the data when a new version is released, especially if they have been bothered by a particular error within the file (which usually has secure cells that cannot be edited). I have occasionally gotten review comments recommending an update to the newest version, too, depending on the issue detected during the review.
