solar shdaing devices and loads

[bootsam]

How do you assess the affect of sun shading devices such as brie soliel? I have drawn some external shading ie the fins etc and wish to see the effect before and after applying the fins. I note that at the moment the fins do not seem to do anything to the loads. Am I missing the obvious?

(note i am a novice user of IES. Have moved up from Hevacomp)

Hi,
You can do the 'Solar Shading Calculation' using SunCast module.
The other lighting modules FlucsDL/Pro & Radiance.

Later on you can link the result of this calculation to ApacheSim to check their effects.

As you said , you are novice user for IES , I would suggest you to go for "IES Training" program.

Suncast shading take very long time for calculating, more blind is much more time, so you can simply use parametric shading in glass material setting.

Sorry there's been a misunderstanding. My fault. I have built the model, drawn the local shading 'louvres'. Run a suncast and assessed the room loads. Now I want to 'switch off' the solar shading and assess the loads without the shading. To see how much the internal solar gain is reduced by the external shading. I guess i have to 'freeze' the shading, do another suncast and then check the loads. But I am not sure how i turn off the shading.
