Simulating IES lamps file through RAD materials

Hi to everyone,

in this tutorial ( http://diva4rhino.com/page/simulating-luminaires-with-ies-files ) is shown a method to simulate a lamp in DIVA. Considering that the process is about a modding of radiance materials, do you think that it would be possible to do the same in honeybee?

To go deeper I have tried to do the tutorial about DIVA, but in its grasshopper version: it doesn't work. To be more precise, the material, applied to a brep, is not read by the DIVA daylight simulator. Actually I don't know if I'm mistaken about some details.

it would be great if only it could be possible in honeybee! for instance I have found this study which is pretty interesting to calculate lamps power consumptions directly in honeybee: https://sites.google.com/site/just4architecture/research/responsive...

Thank you,

Claudio

No, I mean it happens always, but in static analysis I can run it manually and the analysis works.
Sorry , I have been not clear enough

Hi Claudio,

I added an extra check to the component. It will re-run the batch file in case it fails the first time. let me know if it solves the problem.

Hi Mostapha,

it seems working very well. Thank you again for your time you spent for me and for your whole project as well. It has been very helpful for my studies.

Hi Mostapha,

Thank you very much for your reply - the IES to HB component is grey and seems to be working however it gives me no output. Do you know what I did wrong please?(rad and bat files attached) Also I had to double click on the bat file to get the rad one - the component did not generate the rad.

Many thanks

Hello, this is with example file called IES2HB_WIP_III too and the radiance file attached (in this case I had to edit the BAT with the following line to generate the RAD manually "ies2rad -o Test4_NoModif_1.0 -m 1.0 CDM-i_25W_10deg.ies") This is the April version of HBtoIES:

Hi Arthur,

Thank you for sending the files. I wonder if the white space in the address causes all the issue when you run it from Honeybee:

C:\Users\user\Dropbox\COMPANIES\Mamou-Mani ltd\

This is a limitation in the current version, and we are aware of that and will be fixed for next versions: https://github.com/mostaphaRoudsari/Honeybee/issues/13

Cheers,

Mostapha

Hi Mostapha,

Thank you so much for taking time to reply. I tried using the same tool placing the ies file in the C drive here is what the bat file attached says:

SET RAYPATH=.;c:\radiance\lib PATH=c:\radiance\bin\;$PATH

cd C:\Radiance\Tests ies2rad -o arthur_0.7 -m 0.7 CDM-i_25W_10deg.ies

It does create the rad file but the output is still empty as shown below.

I hope you can help again.

Many thanks,

Arthur

Ha! I see what is going on here. In your case the ies file is spherical which I haven't really implemented to IES>HB and that is why it is still in WIP tab. It shouldn't be that hard to implement (it should be added both here and to runDaylightAnalysis) but I will be traveling from tomorrow for the rest of the week and it will be really tough to find a time to get this done but I can apply it early next week if it is not too late.
