Hi, I'm wondering if it is possible to get daylight uniformity from E+?!

Regards

Not directly, but you could put in illuminance maps everywhere, and then review the illuminance data (somehow), to generate the metric. The problems are:

  1. The energyplus geometry model is bound by thermal zone boundaries, not the actual architecture. You have zero truth in reporting at the end of the perimeter zone since the boundary is opaque.

  2. You will need to roll your own solution for reading the illuminance map data from the eplusout.sql file, since Results Viewer is no longer included with EnergyPlus or OpenStudio.

If you're interested in spatial daylight metrics you probably should use a more honest daylight simulation method than EnergyPlus.
