Hi..

I have a question about modelling internal doors in Energy Plus (V 9.6). I exported the Heating Design Energy Plus file from Design Builder ( V 7.0.0.096). I draw one door inside the building that connects hallway to main bedroom. In Energy Plus IDF, I get the following FenestrationSurface:Detailed object.

! Door, 1.999m2

FenestrationSurface:Detailed, SecondFloor:Unit8XMBR_Partition_4_0_0_0_0_0_Door,  !- Door name
Door, Project internal door,             !- Class and Construction Name
SecondFloor:Unit8XMBR_Partition_4_0_0,   !- Base surface
SecondFloor:Unit8XHallway_Partition_2_0_0_0_0_0_Door_10061,  !- Corresponding other surface
0,                                       !- View Factor to Ground
,                                        !- Frame divider name
1,                                       !- Multiplier
4,                                       !- Number vertices
1.9711583543,-29.96357673, 2.64795,     !- Vertex 1
1.9711583543,-30.96332073, 2.64795,     !- Vertex 2
1.9711583543,-30.96332073, 4.647438,    !- Vertex 3
1.9711583543,-29.96357673, 4.647438;    !- Vertex 4

However, I get another FenestrationSuface:Detailed object as below:

 ! Door, 1.999m2

  FenestrationSurface:Detailed, SecondFloor:Unit8XHallway_Partition_2_0_0_0_0_0_Door_10061,  !- Door name - reverse definition
     Door, Project internal door_Rev,         !- Class and Construction Name
     SecondFloor:Unit8XHallway_Partition_2_0_10059,  !- Base surface
     SecondFloor:Unit8XMBR_Partition_4_0_0_0_0_0_Door,  !- Corresponding other door subsurface
     0,                                       !- View Factor to Ground
     ,                                        !- Frame divider name
     1,                                       !- Multiplier
     4,                                       !- Number vertices
      1.9711583543,-30.96332073, 2.64795,     !- Vertex 1
      1.9711583543,-29.96357673, 2.64795,     !- Vertex 2
      1.9711583543,-29.96357673, 4.647438,    !- Vertex 3
      1.9711583543,-30.96332073, 4.647438;    !- Vertex 4

The second one is referred to as 'reverse definition'.

My question is: Are these two same doors? If I create a natural ventilation model and set one of them as "OPEN", will the door with reverse definition open too?

Thanks.

@prp92 what EnergyPlus interface are you using? My guess is DesignBuilder, but you should mention it in your post's title and/or body as well as the tag so that others can provide better help.

Hi,

The internal door and other internal constructions are reversed to avoid the issue that is explained here. https://unmethours.com/question/25452...
