I'm curious what folks think about the submittal requirement to provide Cx and O&M plans to support this pilot credit? The requirement to ventilate per 62.1 during occuancy and to have MERV 13 filters on recirculated air can be demonstrated thru design drawings - this feels like a "design" credit rather than a "construction" credit. I believe the OPR & BOD ought to be enough "proof" that these requirements are project priorities. I'm always striving to push as many credits thru in design review as possible (particularly on D-B-B projects), and it would be nice to be able to check this credit off as part of the design review.

Maureen, I tend to agree. I am having trouble getting this submitted as part of our design review for the same reasons. I'd like to see the documentation better defined to keep the credit as either design or construction.

I've submitted successfully without these documents; however, I am concerned that they will required in the future.

@Christina Hohman, consider this, though: In order to do justice to your commissioning process, the LEED CxA needs to be on board in some capacity during design, to engage in enough design reviews to ensure the OPR and BOD are being met (and that commissioning will run smoothly). For my project that achieved this pilot credit, I was able to ask my LEED CxA to create the CFR/O&M and Cx plan tables of contents well before commissioning started, and we included a section to verify the testing of ventilation systems per ASHRAE Standard 62.1-2016. This ensures that this testing will be performed as part of commissioning later on, so it gives us a head start.

Thumbs up to Allison.
From previous project experience, the LEED consulting / energy modeling / commissioning services were all provided by the same company, which allowed this pilot credit to be implemented (and documented) smoothly.

I agree with Alison that this need to be captured in the Cx plan and including in O&M training. One of the items that needs to be communicated with the operations team is providing adequate ventilation while cleaning personnel are occupying the building, which often occurs after regular operating hours. Our LEED Review team deferred this credit review until Construction.

I agree with the comments; I believe this credit is essential both in the design and construction stages. Addressing it during this stage can be beneficial for HVAC system design. With early and integrated planning in the project, construction delays and additional costs can be avoided. Finally, verifying its proper functioning during the commissioning stage is fundamental to effectively closing this phase.
