[Equest-users] Exhaust Fan Modelling

[Ömer Moltay]

Dear All,

Due to the LEED review comment requiring me to model independent exhaust 
fans in the baseline case that have the same airflow and same power, I 
found out that the only way to do that is to create a dummy HVAC system 
in both models and assign the zones with the exhaust to this system (all 
zones with exhaust are plenum zones, btw). This is the only way that I 
can assure that the energy consumptions are the same between the 
baseline and proposed. Because, especially in my proposed model, I see 
that the exhaust fan volumes are always variable and sometimes they do 
not work at all. Only by collecting them under a new dummy system can I 
get them to work identically to the baseline case (the dummy HVAC 
systems being identical in both cases).

Opinions on whether this would constitute a problem or not are appreciated.

Best regards,
