Dears,
I have some products which are compliant with CDPH method 1.1, and others compliant with CDPH method 1.2. I'm aware that LEED V4.1 allows for CDPH method 1.2, but I don't prefer to upgrade, hence, is it aceptable to report all products (1.1 and 1.2) under LEED V4.
My other question is that, when I state a primer's VOC content that is at the threshold (i.e. the max allowable is 100 g/L and the primer datasheet states 100 g/L), the excel calculator points that the product is incompliant, so, is it acceptable to state the product at 99.9 g/L for example, or get back to the supplier?

Hi Omar, sorry that I don't have an answer, but I do have the same question. My team has been planning to substitute the LEED v4.1 requirements for this credit, but I'm finding that there aren't as many products as I had hoped that have been tested under CDPH method 1.2. I'm also not sure about your question with the Excel calculator, but I'm interested to hear the answer. I don't recall that ever being an issue on previous versions of LEED, so I suspect that they just need to adjust the algorithm in the calculator.

CDPH method 1.1 is accepted for v4.1 substitutions of v4 credit for v4 projects. However, if the project is registered as v4.1 project then CDPH method 1.2 is mandatory. This was the initial guidance. Please see on this discussion for more (https://leeduser.buildinggreen.com/forum/emissions-testing-previous-cdph-v11-2010-vs-cdph-v12-2017)
I do not have answer for the Calculator. Someone else might be able to help you on that.

Hi again!
I was doing some research this morning, and came across this LEED Interpretation from October 2019 that I would like to share with you: https://www.usgbc.org/leedaddenda/10495.
To summarize, USGBC has issued an official interpretation that will allow us to substitute the LEED v4.1 requirements (meaning we can still achieve the credit with a reduced percentage of products complying with CDPH testing), while also using the referenced standards from either LEED v4 or LEEDv4.1. Thank goodness!!!

The guidance I received from USGBC was consistent with the above posted interpretation. Essentially, the stance for this credit is that they will take the v1.1 compliance while v4.1 is in beta or a similar length of time. The logic is that all of the emissions testing documentation expires every 3 years, so eventually this issue will resolve itself and the v1.1 documentation will be phased out anyway.
I would strongly recommend that every v4 project upgrade this credit to v4.1. From my perspective, the splitting of walls, insulation, & ceilings into 3 distinct catagories makes this a no brainer. I find those 3, along with flooring, to be the easiest to document.
