NC-v4 EQc2: Low emitting materials
Can we consider the IBR (Institut für Baubiologie in Rosenheim) an approved seal which is compliance with LEED v4 requirement for VOC emissions?
Attached you will find information regarding VOC test using ISO 16000:

Are throw rugs subject to the credit requirements?
What are the adhesives and sealants to be included in the documentation?
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?

Hi, this is not possible directly, because this seal is not on the list of compliant rating systems as issued by US GBC. And it is even not possible indirectly, as the criteria document requires AgBB conformity, but it does not require the low 0.01 mg/m3 limit for formaldehyde which is required by LEED v4.

We would like to share an answer from the GBCI:
"Testing for the IBR Seal is based on AgBB, which is acceptable for the IEQc Low Emitting Materials general emissions evaluation when used in combination with a French A+ VOC label. The project team should upload a test certificate for each project with the IBR seal to verify compliance with the credit requirements, because the Seal of Approval guidelines appears to indicate that some testing is optional."

That is right. Proven AgBB conformity plus low formaldehyde emissions (which can be proven e.g. by French A+ label) will do.
