[TRNSYS-users] Advanced thermal insulation techniques

[David BRADLEY via TRNSYS-users]

Issmail,

  TRNSYS 3d serves to define the building's geometry. Once you are 
finished defining the geometry then you move from Trnsys3D to TRNBuild 
where you will define (or modify) the materials that make up the walls 
of the building.

kind regards,

  David
