<font size="-1"><font face="Arial">Rohini you are right -- Sun space
does allow for solar transmission through windows if an interior
wall belongs to such a sun space -- that's considering DOE
2.2.(eQuest)<br>
But, I wonder if the split flux method for daylight calcs is a
good choice anyways? . . . .Perhaps it's good for getting a hang
on the energy savings, if you have daylight sensors?!<br>
<br>
I think sun space will be a good quick and dirty way that Vikram
may be looking for if he already has a basic shell chalked out
or can create the shell and internal loads quickly.<br>

will not take care of the cavity ventilation part but will
probably work for the solar radiation part (not sure if sunspace
allows for daylighting - you will have to check on that.)<br>
Another option would be to use EnergyPlus - I think it has an
example file for double facade.<br>
