Daylighting Calculation Anomolie

[Anonymous]

Urgant Help Needed Please!!

Im am trying to run a daylighting simulation....and a perculiar problem appears to arrise. I have simplified a model to illustrate this problem. (please see images)

1. I have a completely sealed off room, i.e. no light can enter the space.
2. I set two partitions within the wall that have a degree of transparency (visible transmittence)
3. When I run the calc. it appears to show an increased in light level against the said partitions. Despite no light entering the zone.
4. If i run the same calc. without any visible transmittence (i.e. opaque) then then it reports a value of 0.0

Thanks
