[Bldg-sim] Radiance and Open studio

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 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!
