Re: [EnergyPlus_Support] about doublefacade

["Michael J. Witte" <mjwitte@xxxxxxxx>]

 If the double-facade space is open from bottom to top, then it could be 
modeled as a single thermal zone that is 8 stories high.  The outside surface 
would be one surface 8 stories high.  The inside wall would be 8 surfaces 
stacked on top of each other (assuming that is interacts with 8 different 
interior zones).  

If the double-facade space must be divided into multiple thermal zones, then 
you would use either MIXING or CROSS MIXING for simple specified airflows 
between the zones.  Or a full airflow network could also be described using the 
COMIS model instead of the simple mixing and cross mixing.

What is the function of the steel grating?  If it is simply to shade some of 
the solar gains, then it could be modeled as an interior or exterior shade or 
blind.
