this is my first time inputting into LeedOnline - as I cannot find interactive help on that site - I have no idea what to put in the columns where the extraction distance cannot be determined - do

We received a declaration from a material producer stating that the product "contains ca. 80% recycled content" and "we assume that 50% comes from post-consumer".

Not sure how it looks in the US, but in Europe we have different concrete classes depending on its strength and - what goes along with that - different material ratio.

The project is using recycled concrete, purchased from an off-site source, to construct a temporary haul road. Can this material be counted towards MRc4 for its recycled content?

Hi! I was reading about the assembly recycled content and I didn't quite get it. Using a window as an example, here we can buy the aluminium frame and the glass separately.

I know MEP components are not included in the MR4 credit. What about piping or duct insulation? Insulation is part of Division 7, so I say it should be included.

One LEED site boundary has two individual LEED projects that are under construction under one contract by the same GC.

The Reference Guide language related to SCMs in concrete gives project teams the choice whether to include SCMs as a percentage of the entire concrete or separate them out (pg.

Re: 2009 CS For both options - Total Construction Cost and Default 45% - are taxes included?

HI, I previously posted a similar message in the MPR forum but there was no reply and am reposting it here as it pertains to MRc4/c5/c6.
