Dear All

I am doing an experiment to see the effect of supply CFM on energy
consumption of building.
I set AHU with VAV and area of model is 25000Sqft.

I am getting following results

Parameter

Auto sized CFM

Increased CFM

Supply CFM

24,222

30,000

TR (SV-A)

77

106

OSA

2970

2970

Energy consumption (MWh)

300

325

I want to know that with increase of supply CFM , TR is increases even
having VAV system.
Is over sizing of AHU fan with VAV have harmful effect on energy consumption
and why TR is changes.
