Hi all,
We received our comments back from the reviewers and it appears we are missing our exhaust systems report. It was found that the contractor who did our air balance reports did not include an air balance report for the exhaust systems, which basically means that no air balance report for the exhaust systems were done for the building during the performance period.
The team was thinking of doing an air balance report for the exhaust system now and having that reported as our submission documentation. The team would be doing a full air outlet test report for the zones and exhaust systems without changing any of the set-points, and taking the readings as is. We do realize that it is outside the performance period, but were wondering if this would be acceptable especially since no set-points would be changed when this test would be done.
The team would also get a signed document from our onsite mechanical ventilation team stating that no set-points were changed during this air-balance report.
The team is assuming that this would be acceptable, because the intent of this pre-requisite is to see the balance between energy use and increased air ventilation, and since we are not changing anything it would still be representative of the pre-requisite's intent.
If anyone has any input on this situation, it would be greatly appreciated.
Thanks

In my experience, it shouldn't be a problem taking the approach you describe. But, just in case you didn't know, air balance reports for the exhaust systems would certainly qualify, but teams often show compliance with much less intensive documentation, such as PM logs that verify fan speed, voltage, etc.

Hi Jenny, one more question. For the measured outdoor airflow for each zone, would it be okay to grab this information from our Building Automation System? Or would it have to be something that we need a formal reporting protocol such as getting a Flow Hood and getting the reading from each individual zone.
Let me know when you get a chance thanks!

Hi Jenny,
Is it not required to measure CFM? Is only speed, voltage, and general operating condition required? It's really not clear on here or in the Reference Guide. Thank you!
