FAQs about MRc5 :

Why can’t I include mechanical, electrical and plumbing components in this credit? What if I consistently include MEP materials in the calculations for all of the MR credits I’m attempting?

We are pursuing IEQc4.5 as an ID credit. Are we thus required to include the cost of furniture in MRc3–7?

What if different parts of a product are manufactured at different locations?

What is the purpose of the newly added Option 2? Can I pursue both options?

How do we account for materials using the new Option 2 equation?

With steel and aluminum products, why do I often get review comments questioning why my extraction distance is the same as my manufacture distance?

NC-2009 MRc5:Regional Materials

Product extraction

Hello, I have a LEED project in mexico city and we are using steel to document this credit. However the extraction is in Japan and it is manufacturated within 500 miles. Im confused if a material has to meet both caracteristics EXTRACTION and MANUFACTURING or if the material could just have one. Thank you very much

In LEED guide says that..... "If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage must contribute to the regional value..." Should i just count the steel percentage of manufacturning ????

For a material to count towards this credit, it has to be extracted, harvested AND manufactured within 500 miles. I think the older versions of LEED only looked at manufacturing distance, but this is not the case now. The material must meet both characteristics. If a portion of a product (10% as an example) was both 500 miles for extraction and manufacturing, you would get credit for just that portion (10%) of the material.

Older versions of LEED (pre version 2.0) looked at extraction/recovery location (MR5.1) and manufacturing (MR5.2) separately. All the current versions require BOTH extraction/recovery AND manufacturing to take place within 500 miles of the project. Now MR5 is still two points but one point is if the total value equals 10% of materials costs and a second point is available if the regional material value exceeds 20% of total materials costs. It's typical for a steel manufacturer to recover scrap steel from all over and return it to the mill to be recycled into new steel. It's also likely that a portion of that percentage of recycled content came from within 500 miles of the project site. In that case, the fraction that came from within 500 miles of the project AND the final point of manufacturing of the "finished" product was within 500 miles would qualify for this credit. It sounds like you're project using steel from Japan would not qualify for any MR5 value at all.
