benches. This procedure should take precedence
over the ceiling system orientation. Omit or reduce the
quantity of fixtures over open floor areas. (See Figure
6-5)
E.
Provide recessed fluorescent fixtures at wall along
mirror in all toilets. A version using two 30 watt or two
32 watt lamps is appropriate. The fixture length need
not be confined to the width of the mirror and should
be sized to double as general illumination in the case
of small toilets. If a shower is included, a ceiling light
should be installed also.
F.
In storage, shelf, or bin areas, mount fixtures in rows
lengthwise over aisles between rows of shelves to
make the most efficient use of the lighting. In areas
over 37 m2 (400 sq. ft.) where stack or shelving row
locations are not known or reasonably permanent,
consider running continuous fixture rows at 45
degrees to the general room dimensions coordinating
the layout with the ceiling system design.
G. Special lighting treatment of decorative areas such as
lobbies, waiting rooms, patios, etc., for architectural
purposes shall be conservative and limited to
efficiently controlled light sources which are intended
for use only on special occasions or to double as
general illumination. Decorative lighting of exterior
areas is not permitted except where it is incidental to a
functional lighting system. The use of compact
fluorescent or HID lamps should be considered.
H.
Corridor lighting energy levels generally shall not
exceed one (1) watt per square foot. This would allow
consideration for special areas such as public
corridors, lobbies or entrances to the building.
I.
Lighting for main gates, flagpoles, and committal
shelters shall meet the needs of the specific project.

Control:
A.
Where fixtures are used which have three, four, or
more lamps, switch the fixture lamps symmetrically for
two (or three) lighting levels.
B.
If large window areas are present, switch fixture (or
fixture rows) nearest to the window separately.
