[Bldg-sim] Bldg-sim] Modeling tool for daylight, Energy, Thermal comfort analysis

[Chris Yates]

Hi Gerfried,

Do you mean KTH Sweden? You said LTH! KTH do some work with Equa 
Simulation AB and their system IDA ICE is very promising. The only item 
on the list it doesn't tick is the daylighting - and only then if you 
want output similar to Radiance. However, if you aren't interested in a 
daylight map it does have a fully integrated window shading and daylight 
model that interacts with the thermal simulation at runtime - like E+. 
To my knowledge, I am not aware that IES satisfies window shading models 
that interact with daylight controls at runtime - perhaps Pete Murray 
could comment.

Best regards

Chris
