NC-2009 EAp2: Minimum Energy Performance
Hi All,
Kindly clarify my doubt regarding definition of CFMd in fan power adjustment calculation. From my understanding and based on previous LEEDuser comments that CFMd is the proposed design supply air flow rate.
But I have got a review comment for a project mentioning that fan power adjustment CFMd should be equal to the baseline supply air flow rate.
As per ASHRAE 90.1, it is mentioned that CFMd is the design airflow through each applicable device.
Kindly clarify
Thanks in advance.

Our process load is higher than 25%. Do we have to justify that?
Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

It is the supply air cfm from the baseline model. This is auto-calculated by the modeling sopftware. The baseline fan power calcuations have nothing to do with the proposed design.
