[esp-r] Insolation through other zones

[esp-r at heikowoehrle.de]

Hello outthere,

is there a way of getting direct radiation from another zone? i'm modelling a
atrium at the moment with five zones stacked over each other, with fictious
surfaces between them.

With the normal calculation it looks like only the top zone gets the radiation
from the glas roof, the other zones only get a diffuse radiation from the top
zone.

This may be appropirate for vertical glazings but with a horizontal glazing the
ground zone should receive nearly all radiation on a summer midday.

Is there any solution via the ish-module oder by calculating the
daylight-factor? I was playing aorund with ish a bit but it looks like it works
only for single zones with a transparent surface to external an not with
transparent/fictious surfaces to other zones.

thanks in advance
