FAQs about IEQc4.2 :

How should graphic arts paint or coatings be categorized?

The standards referenced for this credit have been updated since those listed in the LEED Reference Guide – does our project need to follow the latest SCAQMD Rules and Green Seal editions, or the ones listed in the reference guide?

How should handheld aerosol spray paints be handled?

What are the VOC limits for primers? They seem to be listed in both GS-11 and SCAQMD Rule 1113.

NC-2009 IEQc4.2:Low-Emitting Materials—Paints and Coatings

Anti-corrosive paints for sprinkler system and heating-cooling

Does anyone know if IEQ c4.2 credit also applies to anti-corrosive and anti-rust paints/primers for sprinkler system or heating-cooling instalations? Those pipes are located in the underground garage and in ventilation shafts.

Alicja,If the coatings are used inside the weather barrier on the interior of the building then yes, especially for the coatings used within the ventillation shafts. See the credit language above.

Thanks Emily! Where would you look for a VOC limit for that kind of paints? Those are materials for a very special use, not ordinary anti-corrosive paints. I checked that their VOC content never goes below 500-550 g/l and one has even 640g/l (although my research covers only European market). If I would treat them as regular anti-corrosive paints, the limit that I should refer to is 250g/l! Any idea how to cope with that?

Hi Alicja, I used a similar product on a recent project and found that there was nothing on the market that both complied with the LEED requirement and met what we considered to be an appropriate level of performance for the project conditions. You're probably stuck with the budget method. The good news is that these products are usually used in limited quantity and can be balanced out relatively easily by other products that have very low VOC content.

Right, anti-rust paints for heating instalations must be very resistent as the pipes heats up to 100 deg C. I guess I have no other choice than to use the budget method. Thank you for your help!
