Supporting Documentation

In my opinion, it's overkill. My approach typically is to submit only what is explicitly asked for on the credit form and/or in the Reference Guide. You can always submit the tickets and receipts later if the reviewer asks for it in the comments.

I agree with Craig.

We collect all the waste tickets/receipts but do not submit them.....I agree, they are overkill.  

If GBCI asks for them (which has never happened on our v3 or v4 projects) we then would supply them.

We just provide monthly reports and the calculator.

I agree with David and Craig. Usually we see only monthly reports and calculator in the LEED submission for this credit, and we rarely or generally do not ask extra documentation that is not listed on Reference Guide or LEED Forms. If receipts/tickets are included, sometime its easier to verify information that might be missing from Calculator or monthly report but this happens occasionally. So, its entirely upon project team whether to include or not. Thank you! 

Hi,

I am working on a LEED NC project in California. I have waste receipts and have completed the calculator. It is showing 85% diversification. Whatelse we have to submit? My coworker has a tough time with similar project by submitting the waste receipts and calculator. Any expert advise?

Hello Roshni, 

To meet 2 points requirements the project should divert 75% and four material streams. The Calculator itself is enough to meet the requirement. Waste receipts may be provided, but not required.  Also, ADC and other materials that are included in the calculation even if they do not count toward diversion.

If the project includes commingled waste then additional documentation confirming either project-specific diversion rates or average annual recycling rate for the facility that is regulated by a governing authority should be provided. If the project is not able to provide either of these documents then all commingled waste will be counted as one material stream. v4.1 substitution for this credit is much more relaxed if the project does now meet v4 requirements, v4.1 could be another option.  

Also, it is unclear exactly regarding what issue your co-worker has a tough time. 

Hope this helps! 

Hello Bipin,

Thank you for your reply and clarification. I know what you mean by v4.1 BUT this project is already close to completion with LEED under v4 so I do not think so we can scale up to v4.1.

One more question about waste stearm - do we have to describe waste material specifically in calculator? Currently, I have C&D.

We are based in CA and most of our projects are here and under CALGreen there is a requirement for construction and demolition waste management. So, my coworker had to get a letter from the waste recycling authority about the rate and some other sort of letters though she had provided a calculator and receipts. Is there any example of calculator possibly you could share to see how it should look like and acceptable. I am pretty new to LEED so have bunch of question so will get better idea with visual learning.  

Every v4 prerequisite/credits are available for v4.1 substitution. You do not need to upgrade v4 project into v4.1 project, just any applicable prerequisite/credit can be substituted. 

You do not need to provide more detail description. In material description column, you can provide a brief name of material like Packaging cardboards, Waste plastics, Packaging and waste wood, Scrap metals, and others. (as it suits to your project specific). You can select other columns option, as applicable to the project.   

If attempting via CALGreen ACP, if CALGreen requirements are met project meets requirement of MRc: Construction and Demolition Waste Management (1 Point, Option 1) for 1 point.

Based on your description, your co-worker project included commingled waste and this credit was attempted using regular LEED compliance way, not a CALGreen ACP. Please refer to commingled waste guidance for further information.

Hi Bipin,

Thank you for clarification. Just one last question hopefully, just doing v4.1 credit will be enough or have to provide an explanation on LEED online about it?

Also, we are at very final stage for wrapping up LEED so submitting ACP CALGreen at this point would not be late? The checklist seems to me whole CALGreen plan review and the City of Irvine did not ask for this checklist.

Hello Roshni, 

You can do v4.1 substitution via LEED Online or simply provide a narrative letting GBCI know that you are attempting v4.1 substitution for this credit in the Special Circumstances box in the LEED v4 Form, clearly stating Option and Path attempted. 

I cannot answer exactly about this part. It depends upon the project and how advantageous it is to attempt via CALGreen ACP. You can check -  GUIDANCE DOCUMENT: CALIFORNIA-LEED ALTERNATIVE COMPLIANCE PATHS available at http://www.usgbc.org/green-codes or somewhere, and compare how it fits to your project. The CALGreen checklist is a whole plan review and should confirm consistency between the attempted LEED credits and CALGreen checklist. 

Hope this helps!
