UV Treatment of Intake air?

Beckham, this could definitely be a part of a strategy for achieving this credit, but it's not close to being sufficient in itself. There are a number of specific requirements to meet—see our guidance above.I would say that this would not qualify for an ID credit, because it's already covered under this credit.

Tristan, Can I use this Credit as an ID for a C&S project? Thanks!

Sonia, I would say that this is a bit tricky, because one of the IEQc10 requirements is to earn IEQc7.2, but that credit does not exist in CS, because comfort verification would not usually be in the scope of a CS project.I think if you can show somehow that you can meet the intent of IEQc7.2, and meet all the other requirements here, then there is a reasonable case to make this an ID credit. I would get your approach verified through a CIR before proceeding, given the effort involved.

Tristan, Indeed the Thermal Comfort Survey would not be feasible but the landlord wants to reduce his O&M costs and is willing to add UV filters and IAQ Management Plan language in the contract with its tenants. Will give it a thorough thought and proceed with a CIR if needed.... Will keep everyone posted on the outcome.

Thanks!

Someone already wrote a CIR regarding UV lights on AHUs as an Innovation Credit a few years ago for NC (it may have been for a 2.2 project). You can look that up at the USGBC site but the result was the UV lights needed to be part of a whole strategy to prevent mold and providing clean air. This credit may be a good outline for a successful CIR approach for a CS project.

Thanks Susan! Will check and let everyone know!

Hi all. I checked the LEED Interpretations and Addenda Database regarding UV Lights / Filters and Mold prevention and did not find the CIR mentioned previously (See http://www.leeduser.com/topic/uv-lights-id-credit). Does someone know or can send me the number? I would like to see if it is applicable to C&S V.2009. (The other 2 rulings that are somehow related with mold issues are #2302 and 5146 that are applicable for the C&S rating system.....).

Interpretation #695 might be of interest—I'm not sure.

Tristan, So far there are three (3) LEED Interpretations related to this issue: 695, 5146 and 2302. Will see how the owner wants to proceed and will inform all regarding the outcome.

Thanks!
