Sizing Design Day when "Sizing:Zone" object is not used
Hi, I usually run my cooling sizing simulations without the Sizing:Zone
object because I assume that EnergyPlus will automatically use the SizingPeriod:DesignDay
that I entered, but my colleague argued that I have to create the Sizing:Zone
object to properly assign the Design Days to the simulation and results in the correct sizing of the AC System.
My question is, if I do not create the Sizing:Zone
object and I do not assign the DesignDay
into the Cooling Design Air Flow Method
, what day or which Design Day will EnergyPlus use as reference?
Thank you! Best regards, Hanif
