Hello everyone

I have a question about the design day in EP+/OpenStudio. I understand for now that the DesignDay is for the general HVAC sizing. If I firstly model a whole building with all passive building systems (without any motorized or mechanical elements), could I run this building without DDY file? Is there any negative impact on this workflow? My intention is to separate the passive building/systems simulation from active features in buildings.

Thanks in advance
