[Bldg-sim] Design Air flow rate

[Rathna Shree]

Dear all,

As per Appendix G 3.1.2.8, design air flow rate has to be determined by 20 deg F temperature difference. If the base case is PSZ and each zone is assigned with a separate PSZ system, then the CFM for that zone will be calculated in the software with the 20degF differential. 


The Zones are having high unmet hours. Will it be a correct practice if we increase the CFM in baseline case at zone level to reduce unmet hours. 


Regards,
Rathnashree
