<p>Shiva,</p>
<p> Adjacencies between rooms on the same level and adjacencies
between floors are treated the same way in TRNBuild. There are two
important pieces of information in this case:</p>
<p><br>
</p>
<p>1. the wall construction. This is a list of the layers that make
up the wall and their respective thicknesses. The wall
construction is given a name (such as OUTWALL, GROUND, INTFLOOR)
but these are just names; they do not carry any information about
where the walls are located in resepect to other walls in the
building.</p>
<p>2. the wall category specifies how the wall is positioned. The
choices are EXTERNAL (meaning that one side of the wall will
receive solar radiation), ADJACENT (meaning that there are zones
(airnodes) on both sides of the wall, BOUNDARY (which means that
one side of the wall faces the zone and the other faces a known
(and specified) boundary condition, and INTERNAL (which means that
the wall is entirely contained inside a single zone.</p>

building in Trnbuild with 2 floors. I am little confuse about
the surfaces and walls. Some of you might help me with that. i
checked restaurant example but its a single floor thus upper
ceiling is roof but how does it work when one wants to build 2
or more floors. what option should i choose to make a ceiling
between two floors in wall type or there is other way. Should
i choose INTFLOOR or ROOF or Ground in wall type on Trnbuild?
