Set the shading schedule with Daysim/Honeybee

Hi,

I am using Honeybee/Daysim to run an annual daylight simulation with a dynamic blind system. I have read that there are two methods to set the blinds schedules:

- 1. When there are 50w/m2 on the window

- 2. When there is more than 40% of the interior sensors that surpasses a certain illuminance threshold.

I think I figured out how to do the second option (see picures below)

But what about the first one? how can I set the exterior sensor to check for the 50W/m2 on the window?

Thanks in advance,

Alejandro

Hello Mostapha, I am trying to use the annual shading and lighting profiles from an annual daylight simulation as schedules for an energy simulation of the same building. But I don´t know how to do the convertion. I haven´t found domething like that in hydra.

I didn´t come across that one before. Thank you very much.

Hello Mostapha,

I'm here have a question about slat angle of dynamic shading in grasshopper. From the Daysim page, it says that when the illuminance at the control sensor rises beyond a user specified threshold, the system automatically readjusts the shading system to the next lower setting. I just assume i have two shading state one is from 200-2000 lux and the higher state is from 2000-3000 lux. Do you know what's slat angle of the horizontal blinds within the first range (200-2000) and the second (2000-3000)? And how low the angle can be? Does fully closed state means block any lighting rays which is not really beneficial for daylight level?

Regards

Tracy

You have to create each state of the dynamic shadings separately and you can pick any angle that you like. There is no default shading angle in daysim.

Hi Alejandro,

I'm also exploring the grasshopper recipe that is something similar to your second option. Do you still have your old files? Is that possible to share with me? Appreciate that so much if so.
