Re: [EnergyPlus_Support] Holes in the floor with only convection

 If the two zones have similar temperature controls, it may be reasonable to 
ignore these openings.

For convective transfer between zones, use MIXING or CROSS MIXING for a simple 
model or use the COMIS airflow objects for a detailed model, but read carefully 
the limitations of COMIS regarding large horizontal openings.

For solar radiation to pass from one zone to another requires the use of a 
window subsurface.
