In summary, people indicate that IES-VE, SPOT, Daysim (or potential fork of
Daysim by CBEI), and Openstudio are either capable of doing what you ask or
will be soon. Note that I believe most if not all of these tools use
Radiance in the background.

My name is Stefanie, I work in the Green Building sector in Mexico with
LEED project certification. This year we are trying to take our daylight
models to the next level and be able to achieve all options of LEED v4 EQ
Credit: Daylight. For Option 1, we have to prove a Spatial Daylight
Autonomy of 300lx for 50% of occupied hours per year as well as analyze the
Annual sunlight Exposure of 1000lx for 250h (ASE1000,250).
We are familiar with working with RADIANCE but we are not sure if it is
possible to carry out this analyses and get both results needed. Could you
help me with this doubt?
Hope to hear from you soon.
