Revision history [back]

I am modelling the VAV with water cooled chiller.
I specify the Outdoor air flow rate in DesignSpecification:OutdoorAir as below

DesignSpecification:OutdoorAir,
Office_OA,               !- Name
Sum,                     !- Outdoor Air Method
0.00325,                 !- Outdoor Air Flow per Person {m3/s-person}
0.00039;                 !- Outdoor Air Flow per Zone Floor Area {m3/s-m2}

and refer this specification in HVACTemplate:Zone:VAV as below

However, checking the result Standard 62.1 Summarybelow, it seems that no Outdoor Air is introduced

Can anyone tell me why and how I can fix this problem?
