Dear Matt and Salim,
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.
Best regards,
Knut Erik Enerstvedt

>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?

>Dear trnsys users,
>In zone window of trnbuild, what does wall gain means actually, is it a density flux that we impose at the inside surface of the wall ?
