I understand that the credit language requires the use of the Ventilation Rate Procedure(VRP) from ASHRAE 62.1-2010. I am working with a project team that is considering using an air scrubber technology coupled with the Indoor Air Quality procedure(IAQP). The focus and goal is to reduce OA and energy associated with conditioning OA. Project is located in south Florida so this is a significant element of the building energy use profile. I understand that there is a pilot credit EQ pc68 to enable teams to utilize IAQP.
Is the EQpc68 still available as an option for LEED v4 projects?
Does anyone have any experience/success with this approach? I would welcome any insight and wisdom you may have to offer.

Hello James, could you tell me how was this project for you? It was positive and you achieved the result you expected? now we are working on a project where we intend to achieve the same (reduce OA using IAQP + Photocatalytic clean air systems); I appreciate your comments and recommendations. Our project is in Colombia, South America. Thanks a lot

Jose:
The project ended up using contaminant removal equipement using a gas-phase air cleaning device. We used IEQpilot credit 124 Performance Based Indoor Air Quality Design and Assessment. The project was able to demonstrate acceptacle IAQ perfromance via IAQ procedure resulting in less total OA than a conventional ASHRAE 62.1 venitlation rate procedure. The other major benefit was a substantial reduction in annual energy associated with the reduced OA cfm required. A true win-win!! Project acheived LEED Gold certification! I suggest you look and evaluate PC124 early in the design process as it does require a committment of the HVAC designers to make this happen.
