Honeybee and LNBLWindow

Hi guys,

Was wondering if the idea, more like a request actually, is doable.

Is there a way there can be a link honeybee to LNBL Window, so that we can extract transmittance values or even just add specific and real models and their properties from there?

Kind regards,

Theodore.

Ok this is embarassing, I have no idea why I never responded to this. Maybe I gave up on what I was doing at the time.

I came into an issue with BSDF again I wonder if I'm doign something wrong. I am getting an unknown material type "BSDF" error from radiance when I connect a Windows 7.4 xml glazing file using the radBSDFMaterial HB component.

The model is a simple box, just meant for testing thermochromic glazing. All components updated.

I am attaching the xml file. The material definition seems right

void BSDF ThermoTest
6 0.000 C:/Users/Public/LBNL/WINDOW7.4/BSDFs/LowE.xml 0.000 0.000 1.000 .
0
0

I have Radiance 4.1a installed, so it shouldn't be that. BTW can update to the last version and still have HB working? I should note that grid based analysis worked.

Any ideas?

Kind regards,

Theodore.

I have Radiance version 5.0.a.5 installed and I can apply the material with no issue.

Damn, then it's my Radiance!

Thanks for testing Mostapha, I will try another annual simulation with the new version when I'm at the office tomorrow morning!

Kind regards,

Theodore.

I totally missed the fact that you're trying to run an annual analysis. Daysim is incapable of reading BSDF materials for annual simulation. One more reason that 3 and 5-Phase method is the better solution for annual simulation.

Aha, thanks for heads up Mostapha.

I will wait patiently for the 3-phase method ;)

I wonder, will we still retain the daysim capabilities concerning controls, schedules, etc. with the new method (when it is applied)? Forgive my ignorance on this, I've read the document but I'm not aware of the relationships between them.

Kind regards,

Theodore.

The answer is yes but it won't be using Daysim's scripts. They have so many limitations. In case of schedules we can write our own codes, and for controls projects like STADIC will be used.

Hi Mostapha,
Thanks for this comment.

the other day, I have generated a BSDF (xml format) (for dielectric material) by genBSDF in Radiance.
I have one question; is it possible to generate it with HB? and by any chance, do you know how I can generate it for both (Solar and visible)?

for your information it was the command:
genBSDF -n 7 -c 8000 +forward +backward -r '-ab 50 -ad 1400 -lw 1e-6 -lr -10 -st 1e-6' +geom meter -dim -0.586443 0.586443 -1.65562 +1.65562 -0.103897 +0.103897 Xmaterial.rad X.rad > X.xml

Hi Mostapha,

Can you please elaborate more on _upOrientation_ input of Honeybee_Radiance BSDF component. I already looked at the PDF you referenced in the component. I think, I am still not very clear on. How to correctly set the Orientation vector. I am running a simulation using attached file. When I run illuminance analysis, the result makes it look like I am simulating a plane glass.

I am running a simulation using attached file. The material is applied to a totally horizontal skylight. When I run illuminance analysis, the result makes it look like I am simulating a plane glass.

Thanks,

Devang
