Re: [TRNSYS-users] Adding door TRNSYS 3d

Karol,
 I typically ignore the doors in residential modeling.

 The problem with defining a door as a window is that since it is a window, it will allow solar radiation to transmit into the residence. Of course if you have a glass door on the house, that is entirely appropriate. However, if you have an opaque door, it is better to define the door as a different wall section.

The following steps usually work for me in Trnsys3D, :

1. create the zone that contains the exterior door and make sure that the zone is active.
2. draw the door, starting from the bottom edge of the zone. Once you complete the door, Trnsys3d will "recognize" it as a window.
3. with the zone still active, select the window surface (just the bluish part, not the lines that define the size of the window).
4. delete the surface - you should now have a wall with a big hole in it.
5. retrace the line that defines the top of the door - Trnsys3D usually now "regnognizes" this as a door.

Once you import the *.idf into TRNBuild, you're going to have to be careful because both the "door" and the wall surrounding it will get set as walltype EXT_WALL. You will need to define a wall construction in TRNBuild for your door (probably using a single "massless" layer) and then you will need to change the door surface from walltype EXT_WALL to your newly created walltype "DOOR"

Kind regards,
 David

Nidal and David,

 

I’m not sure if I understand problem, but I have just create single-family house and I modeled only exterior door.

 

I defined this door as window and create this door using WINDOW 6 (software of Lawrence Berkeley National Laboratory – free download): u-value=2.6 W/m^2K and g-value=0.144

 

It seems to me that interior door are also possible to define this way.

 

It seems to me that in Google SketchUp edge of window/door can’t overlap with edge of wall. To respect this you can make door which begin a few centimeters above lower edge of wall

 

I’m beginner in TRNSYS, so I’m not sure if my ideas are well!!!

 

I enclose pdf  with instruction how to create window in WINDOW and introduce it to TRNBuild library.

 

Good luck

Nidal,
  This is a bit of a problem in the Trnsys3D plugin; the developers are working on a solution. I have had some success in breaking my wall up into a "wall" part and a "door" part but this can be tricky because you don't want the door to get recognized as a window. I then set the two parts as different wall types and take care of correcting the construction in TRNBuild.
  If there are not very many doors in your zone, I would recommend that you just ignore them. I only took them into account because I was simulating a garage that had well insulated wall and completely uninsulated (very large) garage doors.
Best,
 David

Dear All

I am working with multi-zone building using TRNbuild, and I wonder if you can help me how I can add or identify a DOOR to the one zone building.

Also I could'nt add or identify a door by using Trnsys3D.

 

Best Regards
