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?

Steel manufacturer letter regarding raw materials extraction

Hi, I need help with interpretation with this letter which I'm sure some of you may have the same from the manufacturer. So, what is % of raw materials extracted within their manufacturing plant? "Gerdau Ameristeel's own steel recycling facilities provide approximately 40% of all the recycled steel scrap used in our steel mills. The individual Gerdau Ameristeel mills select scrap based on metallurgical needs and costs. In general, it is estimated that at least 80%-90% or more of the steel scrap used by Gerdau Ameristeel comes from locatinos within 200 miles of the producing mill and 95%-100% within 500 miles of the producing mill."

Hi Lilian, what do you mean the "manufacturer has removed this letter." I am actually up against the same issue with Gerdau and a couple other steel mfg submittals that have been submitted for me to review. Instead of providing the scrap steel recovery location, they give information just like Gerdau did. How did you get around this? We do need an actual location for this information, correct? Thanks in advance!

Hi Courtney They have provided me with another letter dated April 15, 2009. The letter states that they used recycled scrap metal in their EAP in the steelmaking process. It also states that they are the collecting facility of these scraps.So, according to pp 417 of the LEED 2009 Canada, their collection scrap facility is considered as the 'raw material' extraction location.
