LEED V4 Illuminance Calculations

I am recently involved a LEED V4 NC project. During the process, I found LEED V4’s daylighting simulation has been changed. According to my knowledge ,I knew that Honeybee for Grasshooper can calculate the Useful Daylighting illuminance.

After studied the Honeybee_Annual_Daylight_Simulation_Example form ([http://hydrashare.github.io](http://hydrashare.github.io)), I got the UDLI &lt;100,100&lt; UDLI &lt;2000 and UDLI &gt;2000 .This example is performed very nice.

But the requirement of LEED V4 EQ CREDIT: DAYLIGHT Option 2 need illuminance levels will be between 300 lux and 3,000 lux for 9 a.m. and 3 p.m.

So I am confused. Is the any method for Honeybee to  do this level of illuminance calculations?

Hi,

Grid based simulation shall be used for such point in time analysis.
