How to add horizental and vertical shade for a glazing with using honeybee?

Hi Dan,

Since the component just generates surfaces (breps) you can use it twice and connect both for one shading state in one shading group.

I hope this can help

PS: considering this, you could even design in Rhino your blind geometry than import it into GH with a simple reference and do the same. The component just makes your life easier.

PPS: I would even remember that shadings need a higher quality (especially the bounces number) in the Rad settings :-)

Hi Claudio,

Thank you for your fast reply. I indeed design the shade geometry by extruding the surface which subtract the glazing area. What you mean is that this geometry is equal to the brep built by that component, is it right? But how can I add this geometry into the simulation (energy and daylight)? If I want to consider the material of shades, is it right to connect it to the HB shades context surfaces component in the figure?

And you remind me the parameter settings. I see when the quality should be high, other parameters change. 

Bests,

Dan

Hi Claudio,

I have tried in the condition of high quality, and found it cost far more time to simulate.

Hi Dan,

Claudio answered your initial question so I just reply to the new ones.

1. Yes. You can use the component but make sure to update your components and use the latest. I mistakenly put EPConstruction input for the component however EnergyPlus doesn't consider the constructions for site shadings. There are alternate methods that you can use if it is critical to have this effect in energy simulation.

2. If you are still using the same geometry that I have seen before, then set the quality to 1, and add -ab to a higher number. That should save you some time.

Hi Dan,

It looks like you are using everything correctly but Mostapha is right that you have to update with the "Honeybee_Update Honeybee" and "Ladybug_Update Ladybug"components.

Also, to clarify, the shading designer component that you initially posted is only meant to produce possible shading geometry off of existing window geometry.  It is most useful when you want to generate shade geometry for a bunch of windows really fast.  In order to add properties for daylight and energy simulation to your shade geometry, you use the context component that you posted a picture of.

Hi Mostapha and Chris,

Thank you for your replies. I think I get what you mean. And only the optical parameters of shade can be considered, not including EP construction. I' happy my model is more and more precise.

Bests,

Dan
