Salvage materials under MRc4

You're right Tristan. I don't know for sure and I shouldn't advocate something that may "lead", no pun intended, to confusion or problems later down the road for somebody and their projects. Rightly or wrongly, many people seem to use this forum as an unofficial form of USGBC tech support, which it is not. I should be careful what I advocate. This is actually a question I asked you about on the MRc3 forum. Last I heard you and Michelle were looking into this. Officially the LEED Manual prohibits you from counting salvaged materials in both bins simultaneously, but it doesn't say if you can count something salvaged as recycled for MRc3 instead of reused for MRc4, particularly if it went through some type of "remanufacturing" process. Instead it says remanufactured concrete (crushed concrete replacing new aggregate) won't count as material re-use, since it ostensibly is too far removed from the original material, and lot of the embodied energy & by consequence environmental benefit is lost in the remanufacturing process. On the other hand, a remanufactured coffee table made from an existing door would count as materials reuse. Since it says the reused aggregate will count as a post-consumer material, it seems to me that you may do the same for the wood in the table example, since the wood much like that aggregate mentioned above was recycled from an existing post-consumer source, in this case, a door. The only caveats I see: 1. Don't double count. Pick a category and stick to it 2. Preserve as much of the material identity and embodied energy as possible, especially if you are looking to argue it under MRc3. Still this is just one man's opinion. And while I'd like to think otherwise ;-), this man (aka me) and his opinion in the grand scheme of things doesn't matter that much. Rather it's the opinion of the GBCI who would be reviewing his submittals, and the submittals of the original poster that matters. I was just telling a fellow forum follower how I would handle this credit. Hopefully the lady took it with a large grain of salt. :)
