Rendered illuminance image on task plane (at a certain height)

If you're bound to Ecotect you have to create a grid for the room at the
correct height and export it as a list of coordinates which are then fed to
rtrace. I think Ecotect creates a *.bat file for you with all the necessary
commands. When the calculation is done you load the results back into
Ecotect and visualise the grid.

A Radiance only approach is explained in Axel's Radiance tutorials

I am using Ecotect export to Radiance. In Ecotect, I placed camera to get
illuminance image, but it seems that the output image shows lux levels on
ground level. It doesn't give lux contours on a task plane (at any level).
Can anyone help me out in getting lux levels on a certain height.
