Light fixtures count?

Lorenna—For calculating credits MRc3.1 through MRc6, a CI project must include all materials classified under the Construction Specification Institute’s (CSI) MasterFormat™ Divisions 03 through 10, Division 12, and parts of Divisions 31 and 32. CSI classifies permanently installed light fixtures in Division 26, so they do not figure into the calculations for these credits. Light bulbs (which electrical engineers refer to as “lamps”) also fall under Division 26 and do not count. Through an odd linguistic quirk, interior designers (and the general, English-speaking public) also use the term “lamp” for portable, decorative light fixtures (such as desk lamps, table lamps, and floor lamps). Equally quirky, CSI classifies such portable lamps as “Furnishings and Accessories” under Division 12. LEED-CI requires that Division 12 be included in the calculation for these MR credits. Based solely on CSI classifications, one might be required to include this kind of “lamp.” However, this seems to go against LEED’s general rule of excluding mechanical and electrical devices from the MR credits, so I would be wary about taking this approach.
