[EnergyPlus_Support] Dedicated ceiling void model object

["Jean Marais jeannieboef@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Dear Colleagues,

Should a viability study of developing a ceiling void model be made? The effect on room temperature response / behaviour when modeling a plenum zone vs. modeling an air layer in the ceiling buildup is not clear. The effect on yearly energy usage regarding using a plenum zone vs. modeling an air layer in the ceiling buildup is not clear. If it is significant, then it must be noted that modeling large buildings with many zones, each with an extra plenum zone is currently far too time consuming both in input and execution.

Does anyone have experience in this regard?

Jean
