Hi,
I'm analysing the daylight factor in a room with a double glass façade on one side. In the gap between the two skin there are some louvres for shading.
I carried out several analysis trying to see if there are any differences for different angles of the louvres and different values of the transparency of the window.
It seems that Ecotect doesn't take into account both the glass. Moreover I don't see any difference changing the orientation of the shading.
Could you help me?
Many thanks (and sorry for my bad english!)
Lorenzo
Hi Manens, could you post
Hi Manens, could you post the model so we can check what the problem might be?
Louvre at different angles
Hi,
here is attached the simple model I considered with the louvres at 70°.
- I observed that the dayligthing factor doesn't change if i add or remove the external skin or chaging the transparency of the glass.
Maybe I'm doing some basic errors but I don't realize what.
Many thanks for your help,
Lorenzo
Louver in double glazing
Hi Lorenzo,
I have tweaked a bit your model whereas I have created a full zone with a window as its child.
I have tested it with another model next to it. It seem to work better now.
Ecotect uses some very defined assumptions (esp. regarding the orientation of the objects surface normals, determining what object contribute to the external or internal DF component...) whilst calculating daylight factor, not all understood by me mind you...
Have a look also at the help files under Daylight factor to read about the assumptions and methodology Ecotect uses. It can help you better understand how to create a model.
Best,
Olivier
