Determine which flooring materials qualify automatically under the LEED v4/v4.1 Low-Emitting Materials credit versus which require VOC emissions testing, and under which CDPH method version

Steps

1. Confirm the credit category is LEED v4 and v4.1 Building Product Disclosure and Optimization / Low-Emitting Materials (EQ credit), covering VOC content and emissions
2. Record the inherently non-emitting materials list applicable to flooring found in manufacturer/consultant summaries: stone, ceramic, powder-coated metal, plated/anodized metal, glass, concrete, clay brick, and unfinished/untreated solid wood flooring — these qualify without VOC emissions testing only if they have no integral organic coatings, binders, or sealants
3. Distinguish the required testing standard version by rating system: projects registered under LEED v4 test other flooring products (finished wood, resilient/vinyl, carpet, etc.) under California Department of Public Health (CDPH) Standard Method v1.1-2010, while projects registered under LEED v4.1 require the newer CDPH Standard Method v1.2-2017 for the applicable exposure scenario
4. Note that some cross-version substitution has been allowed via LEED interpretation rulings (e.g., accepting CDPH v1.1-2010 test data on a v4.1 project), so confirm the project's registered rating-system version and check current USGBC interpretation rulings before assuming a test report using the 'other' CDPH version will be rejected or accepted
5. Advise cross-referencing the specific product's compliant-product listing (e.g., FloorScore, Green Label Plus, or the applicable CDPH v1.1/v1.2 test report) rather than assuming a general 'low-VOC' marketing claim satisfies the LEED credit
6. Recommend consulting the current official USGBC LEED v4 or v4.1 reference guide (matching the project's registered version) or a LEED-accredited consultant for exact credit-fraction/point calculations and any applicable interpretation rulings
