Daylight Sensors

Does anybody know what programs are available for modeling the amount of daylight that enters a space based on location, orientation, shading devices, and TMY data? I obviously can not use eQuest to do this...and would like to know what software is available for determining the lumens in a space from daylighting. Any help would be appreciated. Thanks so much!

I would respectfully argue that you can do daylighting calcs with eQuest. We've been using the eQuest program for daylighting calcs on several recent projects and the program seems like it does a good job to me, certainly a good enough job based on the time and budget constraints that we work with on projects.

A quick energy simulation that accounts for daylighting is OK with
equest but I wouldn't use equest for daylighting design, especially
for deep spaces.

I recommend radiance or Daysim.
