Radiance and Open studio

8 posts / 0 new
Last post

Dear colleagues,

I am just starting to use Radiance on Windows, I did the basic course on
Linux before (or on the virtual machine on Windows) and used Open studio
plugin for energy plus models.

I am working with Open studio 1.7.0. and have installed Radiance 5.0 on
windows. I have created the simple model in Sketchup and inserted the
illuminance map, glare sensor and daylighting control in the thermal zone.

Nevertheless, during the daylight simulation Open studio does not seem to
detect the certain file "expandobjects 8.2." (the full error list is
attached). Even though I performed "Scan for tools" operation.

On the open studio forum "unmet hours" people seem to report similar
problems, but it was promised to be solved in 1.7 version... Also it was
said that Open studio somehow is only able to locate Energy plus when it is
installed in the default folder. But it has nothing to do with Radiance,
right?..

Has anyone experienced something similar?
Is there any better way to use Radiance on Windows apart from Open studio?

My .OSM model is attached.

Thank you in advance!

Hi Anna,

I have seen people report success when they reinstall EnergyPlus after the OpenStudio installation.

There was a similar comment regarding Radiance alternatives on Unmet Hours recently, and I'll repost my response to that here:

The Radiance functionality in OpenStudio is constantly improving, and indeed we have a lot planned for the fall release. That said, other options for using Radiance to evaluate daylighting abound, with Daysim, Honeybee, SPOT and LightStanza coming to mind. I would selfishly point out that technically all of these options are "limited" in one way or another; OpenStudio focuses on whole building integration of daylighting results, and does that the best of all the options, while being limited in other ways (which we are working on rectifying).

Dear Anna,

If you are comfortable using Rhino, check out DIVA (http://diva4rhino.com) as well. We have tutorials and exercises for download here http://web.mit.edu/sustainabledesignlab/projects/DaylightingHandbook/resources.htm with more coming within the coming 2 weeks. Our next DIVA training near you will be in London at the Architecture Association on Oct 22-24 before and after DIVA DAY 2015 (http://diva4rhino.com/diva-day-2015).

Rob, to my knowledge DIVA was the first and remains the only tool supporting LEED v4 daylighting credit analysis including blinds use at the whole building level. I am of course happy to learn otherwise.

Best,

Christoph

Hi Christoph,

Apologies, when I said "Daysim" in my head of course I was saying "DIVA". We regret the omission.

OpenStudio does not perform sDA and ASE calculations, however it does do all the other common daylight metrics, _including blinds_, and seamlessly merges the electric lighting results with a whole building energy model. It is this latter point that I hang my hat on. We chose to focus on the whole building integration aspect to the detriment of newer metrics and better interfaces for data visualization. It's a process...

Thank you for your replies!

Christoph,

I am more than comfortable with Rhino, sice my background is in
architecture, but at the small engineering company where I am working now
they do not use this tool. My task was to demonstrate and (maybe) introduce
Energy Plus and Radiance to the comapy's routine. As for energy plus,
additionally to compare it with the local competitor in Austria from
Pokorny tec (http://www.pokorny-tec.at/). If one can call the commercial
software a "competitor" to the non-commercial...

Robert,

following your advice, I installed Energy plus into the default folder and
located it again via "scan for tools". This way I only managed to get rid
of the minor error (URL Found in IDF:
file:files/AUT_Vienna.Schwechat.110360_IWEC.epw but no source could be
located.) I call it minor because I saw it appearing in the error list in
the tutorial, where the rest of the functions were working.

as for the
The job in
'C:/Users/labor/AppData/Local/Temp/OpenStudio.wh4932/resources/run/1-Ruby-0/in/model/radiance/gen_eplus/2-ExpandObjects-0'
did not finish successfully.

ERROR: No tool matching: expandobjects 8.2.-.-

and

failed to run ModelToRad

it is still there. See the report attached.

I will duplicate my comment to the Unmet hours forum as well.

Have you added radiance to your system's PATH variable?

hey Julien, yes I did the second time when I reinstalled it. But it did not
change the result.
