NC-v4 EQc2: Low emitting materials
Hi all!
I have a question regarding LEED requirementes for exterior applied products for schools and healthcare projects:
Does a roof PVC membrane have to comply with these requirements or those requirements are adressed only to wet applied products?
Thanks for your help!

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?

Does anyone know if building site/civil elements have to comply? For example, the v4 Reference Guide states "Two materials are prohibited... coal tar sealants for parking lots and other paved surfaces." However, then in the definitely of building exterior makes no mention of civil/site items AND the "adhesives, sealants, coatsings, roofing, and waterproofinf materials" don't include "site elements" on the list. Thinking about any concrete sealants or sidewalk expansion joint material or asphalt striping paint needing to comply for this credit category. Any help is much appreciated!
