There is a diagram in Jan Hensen's thesis which shows the heights
required for the calculations. See page 4.10 in
<a class="moz-txt-link-freetext" href="http://www.esru.strath.ac.uk/Documents/PhD/hensen_thesis.pdf">http://www.esru.strath.ac.uk/Documents/PhD/hensen_thesis.pdf</a><br>
<br>
Suppose you have a high level opening between 2 zones and that you
specify the connection as a linkage from node X ("positive" node) to
node Y ("negative" node). The height of node X is typically placed at
the average height of the zone represented by node X, say 2 m above
reference; similarly for node Y, say 2.5m above reference. If the high
level opening is at a height of 4m above the reference level, then the
“Height of +ve
linkage point relative to node X” is +2.0m and the "Height of -ve
linkage point relative to node Y” is +1.5m.<br>
<br>
If you had a further low level opening between the 2 zones, say at 1.0m
above reference, then for this connection, the “Height of +ve
linkage point relative to node X” is -1.0m and the "Height of -ve
linkage point relative to node Y” is -1.5m.<br>

<p class="MsoNormal">Can someone clarify the network flow node height
and
component connection designations? The cookbook describes placing the
node at the “height” of the opening, but does not define what that
height should be. If I have a door opening, should that height be at
the bottom
of the opening, the top or the middle? Also, is the “Height of +ve
linkage point relative to node X” supposed to be from the bottom of the
component to the node height, or from the node height to the bottom of
the
component? Same with the –ve linkage node. This would affect
the sign. Again, the cookbook and reference literature do not describe
this completely or clearly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Additionally, the cookbook states that the nodes
on either
side of the component should be at the same height, but what if you
have a
single interior node and windows as multiple elevations? Then only one
of
those nodes could be at the same height as the internal node? I am
just a
little confused on this.<o:p></o:p></p>
