CDPH v1.2 (2017)

Kristen,

What are the differences? I would hedge a guess that the newer version would be acceptable if the changes were to more stringent requirements, not relaxing the requirements.

Yes, the newer version of CDPH (v1.2) is acceptable. We are considering publishing an addendum or other clarification to make it clear that this is an option.

I also recently reviewed European product data that indicated AgBB 2012 (rather than AgBB 2010 as listed in the reference guide). Please clarify if this is acceptable as well.

AgBB 2012, and AgBB 2015 as well, are more stringent than AgBB 2010 because they added more LCI limit values without weakening any other requirement. Technically, these versions should be acceptable as well, but I am not in a position to declare whether US GBC and GBCI will accept these versions. Maybe Larissa would like to comment on this?

Thanks Reinhard, yes the latest versions of AgBB are acceptable. Similar to CDPH, we are considering ways to make this more clear.

Larissa, was an interpretation ever issued on this?

It looks like a very minor update, just to the allowable benzene concentration, based on Berkeley Analytical's summary: https://berkeleyanalytical.com/node/5698

Hi Larissa,

Was there ever an addendum issued to clarify this?  In the past I've had LEED reviewers question low-emitting materails documentation that met a later version of the referenced standard.  I don't want my project team to lose this credit, so it's important to get clarification on this.  Thank you.
