Dynamic Louver_Honeybee_Window Shade Generator

Hi everyone,

I am tying to analyse the effect of external dynamic louvers/blinds on the thermal loads in the building using honeybee components Window shade generator and Energy Shade Benefit Evaluator. I want the shade/blind to be ON, if there is high solar radiation falling on the window. I had set the control type and set point in this case to 1 and 300 W/m2 respectively to generate the results. But, when I change the control type or setpoint input, no change can be observed in the result. Is there something to do with the input in the shadeSchedule_? I had left it default ALWAYS ON in all the cases. Is there any other piece of information I may be missing?

Also, is it possible to change the angle of the louvers depending on the control type, rather than just switching ON and OFF the shading? Can someone help?

Thanks,
Meha

There will be a much better chance that someone can help you here if you share a simple file to reproduce the problem.

Hello,

I am really new to ladybug and honeybee. I referred- https://rhino.github.io/components/honeybee/energyPlusWindowShadeGe... to study the effect of the shades on the thermal load of the building. I tried both the mentioned cases and figured out that only Case 1 (assigning shade before simulation), can be used to study the dynamic shade schedule. Case 2 (shade evaluation calculator) can be only used to study the static shade. I have a few questions regarding the developed shade:

1. Should the two cases generate same results if both of them had same Shade schedule? I observed different results for the two of them when the schedule was default "ALWAYS ON". Is it due to the solar radiation input the two cases take (case 1- total solar radiation and Case 2- only beam radiation)?

2. While studying the shades for different orientation, if i do not want a shade on the north face, can I not not give an input for that case as 0? I tried doing that and it gave me an error?

3. Is it possible to change the angle of the louvers depending on the solar radiation falling the window, rather than just switching ON and OFF the shading? Can I use a different component to study the impact rotating the louvers.

I am attaching the file for further discussion.

Thanks,

Meha
