No reason not to earn this credit
It shouldn’t cost you anything to earn this credit—it will just take a little work (the same is true for the related credit, IEQc4.2: Low-Emitting Materials—Paints and Coatings). Your first priority should be to specify only adhesives and sealants that comply with the credit’s VOC limits, and enforce those specifications on the jobsite. Research low-VOC adhesives and sealants before construction begins and provide lists of acceptable materials to contractors to help ensure that the right products are used.

Documentation
I have a question regarding a core and shell building. So I understand the credit that we have to follow the VOC Limits in the general area of the building/core and shell and require VOC Limits in the Tenant Design and Construction Guideline. Is this what I have to document? Or do I also have to document that the tenant actually follows the LEED VOC Limits?
Many thanks for answers,
Tatjana

Yes, follow the IEQc4 limits for work within the CS scope. According to CS Appendix 4 from the BD&C LEED Reference Guide, you can get Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. for requiring tenants to meet IEQc4 in the tenant guidelines. You don't have to document that they do so.
Low emitting materials in CS 2.0
Regarding low emitting materials such us solvents, adhesives, carpets, in CS2.0. Can I put just one compliant door for example and still get that credit. It is my understanding that CS 2.0 does not address quantities. Same as for the carpets. My project does not have carpets or composite woodComposite wood consists of wood or plant particles or fibers bonded by a synthetic resin or binder. Examples include particleboard, medium-density fiberboard (MDF), plywood, oriented-strand board (OSB), wheatboard, and strawboard., but we are planning to do just a small part with this materials so we can get those credits. Is it possible to earn those credits in such a way?

Yes, you are understanding things correctly. These credits have no minimum materials needed. In LEED 2009, the credit has been changed to address all flooring systems, for for LEED CS 2.0, you can install just some carpet and earn the credit.

Thanks a lot!
fire stopping sealants and duct sealants
I am assuming that the VOC limit for these sealants is "Other" 420 g/l. Can anyone confirm?

Hi Peter,
For duct sealant, there was a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide ruling on 6/26/09 that states duct sealant would fall under "other". However, CIRs from previous versions of the rating system are not necessarily applicable to 2009 but in this case it seems to make sense that the ruling would still apply. For fire stop, I have mostly submitted it under architectural.
Has anyone had luck with submitting fire stop as "other"?
