[EnergyPlus_Support] using IRTMaterial

[Ery Djunaedy <ery.mailinglist@xxxxxxxxx>]

Folks,

I need help on how to use IRTMaterial, the infrared material. I 
basically have a naturally ventilated space with an opening - not a 
window, just an opening where the airflows. The best to model this type 
of surface is to define the infrared material, where (a) there is no 
surface convection (at least can be minimised) and (b) the surface will 
let the solar radiation into the zone.

However, I have encountered the following problem(s):

(a) If I define a opaque surface using this material, the simulation 
runs without any error. However, I cannot report how much of solar 
radiation comes into the zone, or how much solar radiation falls on 
inside surfaces. Obviously this is because those solar variables are 
associated with windows, and since I do not have any window

(b) If I define a window using this material -- so that I can report the 
solar variables -- EPlus will complain because the IRT material is not 
transparent, as required by a window.

(c) If I define the opening as a door, the simulation runs without any 
error, but then again I cannot report any solar variables.

So I am stuck.

Any help will be greatly appreciated.

Ery
