NC-2009 IEQc4.1: Low-Emitting Materials—Adhesives and Sealants
Hi, I want to make sure that the only products that are covered by the VOC-requirements in LEED are the ones installed inside the building when it’s weatherproofed.
For example a part of the building is a garage that is open to the surroundings. Paints and sealants and so on that are used here should not be a part of the documentation?
Thanks Veronika

Do products applied to the weather barrier need to comply with VOC thresholds?
How do I determine what application my product falls under?
How is VOC % less water determined for aerosol adhesives?
Do grout and caulking need to be included, and if so, what is the application category?

If the garage is not connected to the interior space, a past CIR indicates you can exclude it if it meets two conditions: it is unconditioned and open to the air, and it is separated by solid walls.
See Interpretation #1767 from a CIR Ruling on 4/20/2007:
"The project is inquiring if an adhesive used within the exterior moisture protection, but above an impenetrable concrete deck in an unconditioned, non-regularly occupied space, is exempt from EQc4.1. The project may exclude the adhesive in question since 1) the garage is open to the outdoors at all times and thus is not technically an interior space and 2) the occupied areas of the building are separated from the garage by solid, impenetrable walls."
