Hi,
I am modelling a baseline building according to ASHRAE 90.1 2007 as System 7. I would like to calculate the "Sytem Fan Power" in G3.1.2.9 for exhaust fans. However, I don't understant how I can calculate the power of exhaust fan since the exhaust fans are not included in any system in TABLE G3.1.1B, ASHRAE 90.1 2007. Because the calculation method changes according to system type. These exhaust fans are operating in WC and Carparking areas individually.
Best regards.
