Re: [TRNSYS-users] wall thickness impact on zone volume

[David BRADLEY <d.bradley@tess-inc.com>]

PJ,

  The physical thickness of the wall is not counted in the zone volume. It only impacts the thermal properties of the materials. There is not 100% consensus in the building modeling community as to which dimension (inside, outside, or middle) to choose. I typically use the interior dimension for external walls and the middle dimension for internal walls.

kind regards,

 David

Dear support team,

 

I am working on Sketchup 8 to model a house.

What I am trying to do is to trace the internal geometry to build my house model and then apply thickness of the wall.

Generally, how does TRNBLD account for wall thickness in the wall materials, does this just impact the thermal properties of the material, or does this also impact volume? If so, which direction will it impact the volume? Inside, outside, or half-half?

 

Is it possible to assign a wall thickness specifically to go internally to ensure the internal volume will be accurate if I trace external wall?

Or do I have to trace internal walls. The issue with having to trace internal walls is that I then left with gaps in between rooms.

 

 

Thanks in advance.

 

Best Regards,

PJ
