In the tutorial.pdf you
can read this: Surfaces • In Trnsys3d, all
building surfaces (walls, floors, etc.) are represented in 3-D coordinates as
infinitesimally thin. Zone volume and surface area, which are automatically
calculated entities, are derived from those 3-D coordinates. However, you may modify the
volume within TRNbuild. • The construction
that you select for each surface determines the thickness for the purposes of the heat
transfer calculation, but it does not affect any geometric considerations. • Typically, the
building surfaces are measured from the outside edge of exterior walls, and the centerline
for adjacent walls. At the building corners, measuring from the outside edge will overestimate
the total mass of the walls, while measuring from the inside edge will
underestimate it. It is easier to measure the outside edge from the blueprints, but
measuring from the centerline is the more accurate approach. If the walls are especially
thick, consider measuring from the centerline of the exterior walls. MATRIciel sa Ir Manuel da Conceição Nunes daconceicao@matriciel.be P

[mailto:fbetz@aeieng.com] How does Type56 interpret the walls created
in TRNSYS 3D? Should I draw the outer wall surface, the
inner wall surface, or half way in between in SketchUp? Please advise, Fred
