[EnergyPlus_Support] natural convection

[ogocer@xxxxxxxxxxxxxx]

Dear all,
i have simulated a sunspace attached a building has 50 squaremeters area.
i got energy consumption of heating and cooling without defining any
active system. and i used purchased air.idf for defining air supply.
But i didn't define any ventilation flaps.i think something is wrong
because there is no natural convection between two zones.
is it means there is only energy transfer from sunspace to common wall
that seperates building and sunspace?
If  answer is yes, how can i define and schedule ventilation flaps on that
wall and natural convection between two zones?
