FAQs about MRc1 :

For Whole-Building LCA, how do you choose the baseline building?

Is it possible to pursue the Whole-Building Life-Cycle Assessment option late in design?

What is the difference between LCA and LCCA? Our clients often ask for LCA when they really want Life-Cycle Cost Analysis.

My project is a historic building, but there’s no local historic registry. Am I still eligible for Option 1?

How do I account for additional life-cycle impact reductions if my building is designed to last for more than 60 years?

How does the LCA consider operating energy? Isn’t that going to be the biggest source of environmental impacts?

Hi, I am working on a new building project which is pursuing LEED certification and excavation filling from a different construction site nearby will be used for the new building. Is excavation filling material applicable for NC-v4 MRc1: Building life-cycle impact reduction, option 2 as a foundation, slab on grade or subfloor? If it is applicable, what documentation would be required by USGBC. Thank you taking the time to think about this

You're basically talking about aggregate, or the equivalent? I don't see it as applicable here, no.

Hi Tristan and Shane, what do you mean with "equivalent"? Do you think high grade excavation filling material to be used as aggregate in structure (e.g. foundation, slabs etc.) should not apply for the credit? Thank you in advance

Say more. How do you want to apply it to the credit?

Hi all.  There seems to be a confusion on how the soil from a nearby site would be used in this case. Filling is probably the soil to fill any spaces after the underground structure is finished. Aggregate is probably sand or stones to be used in concrete.  Whatever use the nearby site excavated soil has, the only thing that would change in an LCA calculation seems to be the distance from an usual source and for this project. Being able to change the distance from a material from the baseline building to the design building is possible on the software I've used for LCA calculation. The impact of the soil in an overall building life cycle assessment may be minimal though.
