Dear All,

I am modelling plenum zones in the building to simulate exhaust from
toilet / kitchen etc. Please see the attached screenshot for the exhaust
set-up. However, when I zero the kW/cfm value, I see no change in the
total building energy consumption. I also double checking by attaching
an electric meter for the ventilation end use in this zone, and the
meter shows zero consumption. Any ideas why this could be happening?

Thanks,
