Autodesk Ecotect Analysis - Desktop Tools

[#1]

I am having problems simulating artificial lighting in Radiance when using the calculation wizard for Radiance.

Eventhough I at the final step specify to generate the light automatically from the pull down menu, my radiance simulations do not contain any artificial light, but only daylight.

When simulating the artficial light levels within Ecotect everything works just fine.

I would be very grateful for any feedback

The light fixtures IES photometric data is not defined in radiance

you need to convert your IES photometric data to the radiance format.

Try using the IES2RAD utility.

Here are a couple of links for you to check out.
