[EnergyPlus_Support] hours set point not met > 600



Hello Group,

I have a building that shows more than 600 hours set point not met. This is mainly due to the fact that the building is one story with many doors to all four sides.

My doors are set to be openable during occupied hours and are set to being open 5% of the time to 100% open.

Designbuilder uses the following for airflownetwork set up:
 
"Calculated

The average door opening size used in the simulation is calculated by multiplying the % Area door opens (80%) by the % Time the door is open (5%) by the gross door area(2 m2). A schedule can be applied to control timing of the opening(occupation schedule)."

Q1) So I have an average door opening of 0.05 x 0.8 x 2 = 0.08m2. I'm trying to see how this works with the Airflownetwork objects...I may have entered a 100% open, but either way I can't make this add up withh the objects below.


As an example:

Q2) Are the time set point not met hours excessive and if so...how to combat...or make 90.1 compliant.
