Sda simulation with HB+


Hi, all

I am now trying to do SDA simulation and I understand the background knowledge of the modeling methodology.
Though I know HB+ has ability to perform this simulation, unfortunately I have no idea how to implement it.

As I know that blinds or shades should be operated whenever more than 2% points receive direct sunlight, the problem is how to define the sensor, i.e. analysis point in HB+?
I found that some index value need to be provided to sensor component, but what logic to define the index number? nearest one from the window? if the room has 2+ different direction window, how to select it? if there is more than 100 points, need to provide more than 2 index?

If it possible, can anyone share the HB+ sda calculation file?
I am really appreciate your help.

Thanks and regards,
