Is it mandatory to run the model on Radiance when the model has been built up on Ecotect? I have been facing issues on installing Radiance because of my computer windowns version.

The reason is that Ecotect only can run under uniform or overcast sky. You can install desktop radiance version.

Whats your issue with Radiance, can you not get installed or can;t you get it to run with Ecotect? If you could expand your issue i may be able to help. I'm running the latest of everything and have had no issue with installing Radaince. Linking them all together was tricky. http://web.mit.edu/SustainableDesignLab/projects/TeachingResources/GettingStartedwithEcotectRadianceDaysim.pdf

Thanks for your responses. Radiance is not installed properly for an unknow reason. Radiance doesnt find rview and falsecolour.exe files. When I run the simulation and try to import the results, it says: invalid file format - no data found.

Ahh yes, i had that problem. You need to install desktop radiance and link those files. When you setting up the simulation in Ecotect, do you get all green checks on your links?If so, where are you saving the sim file. It should have a very short path name. I save it to my C drive to get results then move it to the server.

Todd, the link you sent below is of help! Thanks very much for this! Now the green checks are all OK and the simulation is running properly!

If the software can't find the file, it is usually caused by newer version radiance that you installed. You can try older version of radiance. I believe the newer one is no longer use falsecolor.exe, but,as i remember, it uses falsecolor2. Check your radiance folder whether you have the file that the error mentioned.
