Hi!
I have got a question regarding ASHRAE G3.1.2.10 "Exhaust Air Energy Recovery" which has to be applied to the baseline model.
It says that at a minimum outdoor air supply of 70 % or greater of the design supply air quantity the baseline should be modeled with energy recovery.
For this calculation do I use the outdoor air quantity over a whole year? Or can I take the m³/h-values derived from the sizing run and the minimum outdoor air rate?

Sounds like it is based on the design supply air so that would be based on the peak loads at design conditions.
