Question-and-Answer Resource for the Building Energy Modeling Community

The illuminance map data is easily viewed (one space at a time) using Results Viewer, which comes with OpenStudio. This works the same whether you used EnergyPlus for everything, or if you also used the Radiance measure for the daylighting. In the latter case, the illuminance map data will be in radout.sql.
Further, if you use the Radiance measure, each space's illuminance map is saved to a separate CSV file. The file header has all the info you need to reconstruct the data into a grid.
Lastly, all the illuminance map, daylighting control, and glare sensor points that were calculated in the model are stored in the file run/[radiance_measure]/radiance/numeric/merged_space.map. This file has the point location and view vector (x,y,z,vx,vy,vz) of every point. Together with the illuminance output (run/[radiance_measure]/radiance/output/merged_space.ill), you could generate a whole building 3D illuminance map of your data! I'm not saying this is necessarily easy, but the information is there for the plotting. A "Radiance Data Visualization Report Measure" is on the OpenStudio development team's wish list, but it's a long list. =)
