Assigning blinds to a horizontal window

Hi everyone,

First of all, a question for you: is it possible to assign a blind to an horizontal window in Energy+? I never tried but until today I didn't think it would have been a problem to do it.

I'm actually struggling with the "Honeybee_EnergyPlus Window Shade Generator" component in order to assign some blinds objects to a couple of horizontal windows situated on a roof surface.

If I set to true in the "horOrVertical_" input I get this error message:
"1. Solution exception:step must be less than 0".
If I set it to false I get this error:
"1. Solution exception:Local variable 'normalVectorPerp' referenced before assignment."

If I slightly rotate the surface so that it's not horizontal anymore the blinds appears in the brep preview but they don't respect my input values for depth, distance between the glass and the shades and so on..

At this point I'm not sure if it's a problem in the HoneyBee environment or if it's not possible to do something like this in Energy+. I look forward to hear your suggestions.

Thanks in advance,

Claudio

Hi Chris,

your new component looks very good! Thanks a lot!
Now I look forward to see the result of your work on the other parts of this component. It looks really promising and, personally, I'm really interested in the opportunity of using the "WindowMaterial:Shade".

Meanwhile I'll keep using blinds and I'll let you know if I find some relevant bugs.

Thanks a lot and all the best,
Claudio

I have finished adding in all of the features that I sad I was adding a couple of weeks ago (it turned out to be a lot longer than initially anticipated). There is now full support for setpoints and all types of shadingcontrol with these setpoints:

Hi Chris,

Does the new component feature thermochromic support?

The implemention of thermochromic glazing in E+ seems straightforward enough, but its extensive nature (a different material for each of the temperatures) makes their custom creation quite painfull.

At the moment, I am guessing because I haven't tried yet, we could use the BSDF export in WindowsLBNL on their thermochromic materials for Daylight simulations? I wonder how close we are to providing the functionality in HB for Energy simulations (if we are not there already and I missed it!).

Kind regards,

Theodore.
