NCIDQ IDFX Practice Test 13

Project scenario: boardroom and workroom lighting

A designer is preparing the preliminary lighting layout for a tenant renovation in an existing office building. The 30 ft by 20 ft boardroom has a 10 ft gypsum board (GWB) ceiling. The adjoining 16 ft by 20 ft workroom has a 2 ft by 4 ft suspended acoustical ceiling (ACT) grid at 9 ft, with a 4-ft-wide GWB soffit at 8 ft along its south wall to conceal existing ductwork.

The client wants the art collection on the boardroom west wall lit evenly from top to bottom, a dimmable decorative fixture that defines the 16-ft boardroom table, good conditions for video calls on the screen at the east wall, and uniform, economical general lighting in the workroom that fits the ceiling grid.
