I am seeing a discrepancy between the LEED template and the IDC reference manual for EAc1.2.
The reference manual for second point (B) states the daylighting must be for 50% of the lighting load. The template states 50% of the connected lighting load in daylit areas. Which is it - total lighting load or lighting load in daylit areas. Second, if it is the later, what is the definition of a daylit area (15 feet from window or skylight)?
Thanks

We got clarification on this question from GBCI directly:
"The current template is a BETA version and I can see the discrepancy. The issue is fixed for the post-BETA form which will be available shortly. The appropriate calculation for OPTION B is using the total lighting load in all areas.
Daylit space for this credit is 15’ from window or skylight."
