In the LEED-NC credit form for SSc8, there is a box that exempts hospitals from the interior lighting requirement. This exception is not listed in the Green Building Design and Construction Reference Guide, nor is it listed in the addenda. Interestingly, this exemption is not listed in the LEED for Healthcare Rating System or supplemental reference guide. Anyone know where this exemption originated from? Also, any insight on whether this exemption could be applied to LEED-HC projects, such as emergency rooms?
