FAQs about EQc2 :

Is all solid wood considered inherently non-emitting? I’ve seen sources that say only solid wood flooring counts as inherently non-emitting.

Are throw rugs subject to the credit requirements?

If a ceramic tile receives a top coat after it is manufactured, is it exempt from the credit requirements?

What are the adhesives and sealants to be included in the documentation?

I'm looking for a certification that tells me if a given product will meet the LEED v4 requirements, but I don't see one in a given product area. Am I missing something?

When products claim that they meet California Section 01350, does the product also meet LEED v4 requirements for low-emitting materials?

How do I know if a product complies with LEED v4 or if it was tested under an older non-compliant standard?

In past versions of LEED, it was easy to specify VOC limits. Is the specification process the same for LEED v4?

Is there a VOC budget method for this credit?

What are the limits on the VOC budget method?

Do products applied to the weather barrier need to comply with VOC thresholds? 

If one part of my multicomponent wall system is not compliant, can I still get full credit?

Our building is atypical, and the walls and ceilings are not clearly defined. How should we classify these components?

NC-v4 EQc2:Low emitting materials

General Emission Evaluation - Default Scenario

The LEED guide states the following: “Building products must be tested and determined compliant in accordance with California Department of Public Health (CDPH) Standard Method v1.1–2010, using the applicable exposure scenario. The default scenario is the private office scenario. The manufacturer’s or third-party certification must state the exposure scenario used to determine compliance.” My question is - does this mean that we can only purchase products that have been tested under the scenario that meets our project type? e.g. if we are certifying a school we can only use products that have been tested under a school scenario?

Hi Mercedes, You are safe using products tested under the private office scenario for any space type, including classrooms. This just means the product was tested under smaller room conditions (equivalent air volume of small space) as a more stringent evaluation of its VOC emissions/IAQ impact to occupants. Products meeting this small office scenario would be acceptable /pose no greater IAQ risk for larger spaces. Make sense?

Yes, this makes sense. Testing under the private office scenario implicates the sharpest requirements. If a product passes under those conditions then it will also pass under the classrooms conditions. It is only the other way around: If a product is used only in classrooms, then it is deemed good enough if it passes the test under those conditions, even if it fails under the most stringent conditions (the private office scenario).
