How can I model a wall occupied completely by a window with direct radiation but that wall adjacent to a conditioned space

Jose

I have to say that I'm not 100% what you mean.

If I do understand you correctly, this is a boundary piece of glass/wall separate from the room? If this is the case, then don't model the wall/glass, but adjust the glazing and fabric on the actual room surface to account for any dissipation of direct solar radiation by the boundary wall/glass.

You have to consider that the software doesn't treat the construction as an actual 'room', but a number of surfaces that are affected by conditions, dependent on their type. For example, an internal isn't affected by a direct solar component, an external (and by association, glazing) is affected by a direct solar component.

Hi Duncan ... sure it was not well explained. Can you see the jpg inserted? I am interested in the blue room. What I want to simulate is a not exposed window which is adjacent to a conditioned room whose longest external wall is in fact a window. So I want to take into account the radiation but no conduction as the internal window is adjacent to a conditioned space. I hope now is clearer.

Hi José,

Thanks for the info, it looks like you need model glazed surfaces on an internal partitions. It is possible to accomplish this in Hevacomp, however you would need to use Simulator to do so. The steady state Design Database calculations cannot take internal glazing into account in this manner.

If you wish to use Simulator, then to model this you would need to use the 'Atrium Partition keywords', as described in the Simulator > Design Data section of the manual, eg:

Glazing and opening

> Full height glazing          /AtriumGlass  5/

This creates a full height internal glazed panel from floor to ceiling between the adjacent room and the atrium space.  The required glazing type (5 in the example) is specified, from the table of glazing.

Hello Shane,
I´m trying to create the atrium, but I´m not doing properly. In the image I inserted before, the Atrium would be the room with the word CONDITIONED. I first created the keyword ATRIUM, then created the room named ATRIUM/1, and then created a partition named /ATRIUMGlass 5/, but it does not work, possibly because I not specifying correctly the partition and the ATRIUM envelope/skin.
An example would be of great help if you have one.

Hi José,

I am looking into this matter via the Service Request you also logged and will be in touch shortly.
