I have this very symmetrical building and EnergyPlus warnings as follows,
* Warning * Indicated Zone Volume <= 0.0 for Zone=THERMAL ZONE: 1ST FLOOR A * ~~~ * The calculated Zone Volume was=-188.78 * ~~~ * The simulation will continue with the Zone Volume set to 10.0 m3.
* Warning * Indicated Zone Volume <= 0.0 for Zone=THERMAL ZONE: 2ND FLOOR A * ~~~ * The calculated Zone Volume was=-188.78 * ~~~ * The simulation will continue with the Zone Volume set to 10.0 m3.
I can set the zone ceiling height to what I know it to be and the warnings go away. Leaving on auto calculate and I get negative volumes. Not a show stopper but just very curious as to what might be at play here.
