Dynamic daylight simulation

Hello,
Could someone help me with the dynamic daylight simulation?
I want to simulate the daylight performance with dynamic shading. But both of the components in the attached figure cannot work. Whether I turned on or turn of the shading device, it has no difference to my daylight results (sDA). Could anyone tell me why?

Hi

this workflow is for energy assessment and does not work for daylight metrics
you should follow this topic

Hello,
Thanks for your help.
So we cannot alter the visible transmittance during the daylight simulation, right? Which means we cannot model thermochromic glazing.

Best wishes.

you can alter visible transmittance by HB dynamic aperture. take a look at this workflow
dynamic_apertures.gh (88.3 KB)

but basically the thermochromic glazing automatically adapts itself by radiation set point. in fact you need control feature but in the daylight simulation there is no control capability. now imagine you have an annual program hour by hour for your thermochromic glazing; in this case you can simulate it dynamically by that workflow.
