Re: [EnergyPlus_Support] Re: DoubleFacade



You can have a window construction that has both:
Would look like this:

Construction,
ExteriorWindow,    !-Name
VE1-2M,               !- Outside Layer (WindowMaterial:Glazing object)
1/2 Inch Air Gap,   !- (WindowMaterial:Gas object)
Clear 6mm,           !- WindowMaterial:Glazing object  
18 Inch Air Gap,    !- (WindowMaterial:Gas object)
Clear 6mm;           !- WindowMaterial:Glazing object  


The WindowProperty:Airflow object 'must be used for a window with two or three glass layers... for three glass layers, the airflow is assumed to be between the two inner glass layers.'

If you do decide to run both, please let me know how they compare, as I've always been curious about that.

Actually I defined it as a new zone becouse I want a double glazing facade and not just a ventilated one! But maybe I could try both the solutions and maybe your strategy will be easyier... thank you
