Solar gain distribution between zones in Solar enclosures (Construction: Airboundary)

Hi all,

Does anyone know how the solar gain is distributed between the different Zones that compose a Solar enclosure (one or more surfaces defined as Construction: Airboundary)?

We are making tests with a thermal model for a space for which we have temperature recordings. The space is a large hall, which is connected to some other adjacent space with Airboundaries.

Surprisingly, the resulting air temperature from the Model is only close to the recordings if we eliminate the Airboundary between the spaces. When we add the Air boundary, temperature drops by 4-5ºC in the relevant space - which is making me think that the solar gains are not being distributed correctly between the zones that compose the Solar enclosure. Is this possible?

I´d greatly apreciate if anyone could throw some light on this. Best, Rafael
