[Bldg-sim] modelling of curtains

[David BRADLEY]

Leen,
  I would think that the approach would differ depending on whether the 
curtains were right up against the window or if they were in a doorway 
between two zones. I would also guess that there would be some 
differences in approach depending on what simulation tool you are using. 
In TRNSYS, curtains up against windows can be handled as a window 
shading device. For curtains separating two zones, you could model the 
opening as an adjacent window (using the virtual /open window 
properties), which would then allow you to define a shading device and 
pass solar radiation from one zone to the other. You can also define 
coupling airflow depending on whether the curtain is open or closed.
best,
  David
