Revision history [back]

I've got a building where there's a double skin facade (actually two, one west, one east), spanning 2 stories. The double skin is open to the outside, but not the inside.

In the winter the outside air is drawn in the cavity by dampers located at the bottom. In the summer the dampers are closed and the air is drawn through direct evaporative coolers.

Each zone is served by a water source heat pump which takes its outside air from the double skin cavities.

How would you go about modeling this in EnergyPlus? I cannot seem to figure out a way to have the outside air of the AHU being drawn from the cavity.
