I had a clarifying question as we near our final construction submittal for LEED. Our building consists of occupied space for City Hall with 5 retail spaces on the ground floor.

My project is a Lab building with labs and offices.

Hi all,

Looking for some help finding Material Ingredients Option 2 documentation for the following products:

Do I need to submit the purchase invoice or any other documentation confirming product acquisition when applying for Building Product Disclosure and Optimization credits on LEED Online?

Can REACH and Global Green Tag certifications count for the Optimization even if they aren't international projects?

If an HPD inventory includes the following information: "Substances representing 95% of the product weight are reported at 100/1000 ppm threshold and substances representing 5% of the product weigh

Hello,

   I'm looking for confirmation on what counts as 3rd Party Verification for these two types of Material Ingredient Reports:

LEED manual clearly says that an HPD must report ingredients at or above 0.1% for compliance with Option 1.

If a manufacturer provides an inventory of all potentially hazardous ingredients (up to 100ppm) but omits ingredients that pose no risk and does not list them, does the report qualify for Option 1

Hi everyone,

the project I am supporting at the moment is following the alternative international compliance path where we have to meet the 100ppm REACH criteria.

Hi!

I recently received a rejection comment for an HPD:   Reason given - Publication Date (01/25/22) is after the projects construction period ended( 12/01/21).  This particular product

Dear all,

We have a project registered on the V4 version of LEED.

I have a project in Canada (metric units) but the client wants all documents in Imperial units. Is this a problem for LEED during the review process?

My project is using a pre-fabicated panel (walls and ceilings) inclusive of doors, windows and ceiling grid lights. All of these components are part of the panel design.

Can anyone offer some input on Green Circle certified products and how or if they can contribuit to this credit?

I'm grasping for one last point here.

Dear All

We are looking for examples for Option 2 for:

- Material Ingredient Screening and Optimization

- Advanced Inventory & Assessment (HPD or Manufacturer Inventory)

The following credit language introduced in LEED v4.1 leaves me with some questions regarding Declare labels:

Hi LEEDuser community, 

I wanted to confirm my understanding of the distinction between the different option pathways for Cradle to Cradle certificates (bulleted below):

Hello Everyone!

Very curious why both LEED 4 and 4.1 restrict the Candidate List to "the version in effect June 2013"?

HPDs have a box to check for 3rd party verification. Does Cradle to Cradle in and of itself earn the 3rd party certification? Is it both for C2C and Material Health Certificates?

I am working on a project where I must choose the materials for the MRc4 credit - LEED V3 (gold certification).

I have 2 products that state they are LBC 3.0 Red list compliant.  If these products meet the requirements of the USGBC Declare Compliance Graphic can LBC 3.0 Red list compliant contribut

European paints manufacturer only justifies the fulfillment of REACH to 100 ppm, arguing that 1000 ppm level of analysis only suits with gas products.

The Reference Guides for both v4 and v4.1 state that:
