Automatic window shade inclination to block the direct sunlight

[mikkel]

Hi @LaFleur,

@LaFleur

As you recommended, I inserted a list to create each type of slat with the inclination that the slat will have for at least once a year. But if I´m doing so, won’t the analysis be performed as if all the slats were present in every hour, because they are part of the ApertureGroup?.

No. It will do a simulation of each state individually.

@LaFleur

How can the “States” input of the “Metrics” component, create a dynamic calendar (unless you have to switch off some hours, such as using an occupancy schedule), if the simulation has already taken place?

As mentioned above the ray tracing of the states are performed individually. This means that when creating a dynamic schedule in post-processing we pick and choose which results (states) we want for each hour. That’s why I previously mentioned the following:

@mikkel

If you want a very specific angle of inclination for each hour it can quickly get out of hand.

In this case you are not doing just 1 simulation. You are doing 511 simulations.

Remember that the states schedule uses the integer value. The first state is 0, the second is 1, the third is 2, etc. The order is the order at which the states are added to the ApertureGroup. Your states schedule should be a list of integer values.

I tried to let the simulation run on low Radiance parameters (roughly 30 minutes). Below you can see the difference in DA with and without states.

Without states (always default state)

With dynamic states schedule

Here is the attached file. I changed the schedule so it matches what you want to achieve (I believe).
