<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>One
example of usage for "wall gain" is when you have defined a boundary
wall with known boundary temperature, but also want to take into account solar
gain from windows on that wall. You can not (at least in TRNSYS 16) define
windows in the normal manner on boundary walls. For example, if you are
modelling a zone adjacent to a highly glazed building with known temperature,
and a glass wall separates the two. Then you can use "wall gain" to
impose the solar heat flux from the adjacent building on the boundary wall.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>>To
the best of my knowledge, and according to the documentation, it is indeed an
energy flux to the inside wall surface. When does one >use this, I am not
exactly sure. Perhaps when there is chimney in a wall with hot exhaust gases
that is causing a gain to the zone?<o:p></o:p></p>
