Hi - a masonry subcontractor provided me with the total cost of the CMU block, however, he broke out the recycled content of each component of the CMU, i.e., he gave me the % of cement, fly ash, re

Hello, I have a question about construction costs to calculate the recycled content value of my LEED project.

Looking to confirm: We are using subgrade Fill for our building project that was procured from an on-site location.

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.

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.
