We are registed for commercial interior rating system , the system installed in our project is vrv system, in order to comply with optimize energy performance EAC1.3 , critical path supply duct pressure loss ,so should i calculate duct pressure losses for all ducted indoor units or only for fresh air indoor units despite that the fresh air unit is connected to vrv system .
Thanks

Could you be more specific about which Option you are pursuing under this credit and where the item you are referencing is mentioned?

refering to optimize energy performance option 1 - equipment efficiency - it is mentioned in the requirments of this path to comply the advanced building core performance guid sections 1.4,2.9 and 3.10.
for this path mechanical system design calculations must be included, the load , fan sizing , critical path supply duct pressure loss.. so my question is should i calculate critical path supply duct pressure loss for all indoor units or only for fresh air units.

I think it is referring to all of the supply ducts.
