conductive material support system such as ‘Ezi-Fix’. Supporting off other services or ceiling
hangers is unacceptable.
Downlights shall not be used for general illumination unless they are of the compact fluorescent
type and then only with the express agreement of the Superintendent. Incandescent downlights
may only be used where required for specific tasks, with the approval of the Superintendent.
Downlights are not to be used in external areas unless specifically approved.
All luminaires other than those for street and pathway lighting shall be installed at a maximum of
3000 mm above f.f.l. Installation shall provide easy access for maintenance, and locations such
as ceilings to voids or over stairs shall be avoided.
Light fittings in ceilings shall be mounted in accordance with the requirements of Section 14.00
Ceilings.
Artworks Display - The public areas of buildings may be used to display the University's Art
Collection. Liaison should occur at an early date in the development of the plans with the
Director, Griffith Artworks and the Superintendent to designate ‘Gallery’ areas.
The following guidelines are indicated for such gallery areas
;
Designated walls in gallery areas should receive no direct sunlight.
Lighting in designated gallery areas should provide an even illumination of the wall.
Where fluorescent lighting (generally preferred method) is used, such lighting shall use low UV
fluorescent lamps or have lamps fitted with UV absorbing polyester sleeves.
Where incandescent lighting, such as spotlights or wall washers are used, they should be
dimmable to allow adjustment of the lighting level between 50 lux for works on paper and 150 lux
for works on canvas. Where spotlights are used, they shall be at least 2 metres from the wall,
mounted on’ Eurotrack’ type lighting track.
‘Gallery’ areas or walls are to be kept free of services outlets and equipment e.g. clocks, GPO’s,
data/voice outlets, EAC card readers etc.
Signage - Illumination of Signs and General Displays shall be provided with a maintenance
illuminance in the order of 200 – 300 lux. Lighting shall be placed so that unwanted reflections
shall not occur on the sign. The luminance factor of the surface of numbers, letters or symbols
shall be not less than 0.3 (30 percent) different from their background.
Auditoria, Lecture Theatres, Seminar Rooms, Teaching Spaces – These spaces or the like
shall be provided with illumination complying with AS 1680.2.3.
Lighting shall also comply with AS 1428.1.
In addition to the requirements of this Standard, adequate focussed lighting, without excess
shadows, shall be provided on both the face of the presenter for lip reading and on the interpreter
for sign language interpretation. The proposed lighting solution for this requirement is to be
approved by LES.
Lecture Theatre lighting shall comprise a lowerable ‘lighting beam’ system along the principles
used in Buildings GH1, Medicine & Oral Health Centre and G30, Arts & Education 1. Details of
these systems are available from OFM.
Videoconferencing Rooms - The illumination to these spaces shall comply with the
recommendations of AS 1680.2.3 – 1994 clause 10.15. The minimum illumination level in the
room shall be 360 lux.
Luminaires within such rooms shall employ linear 4000
o
K fluorescent lamps and Y5 diffusers with
a lighting control system interfaced to the AMX audiovisual system. The lighting design shall
achieve uniform and diffuse lighting in the vertical plane to eliminate facial shadows.
Stairs and Ramps - Within stairwells, luminaires shall be mounted on the walls or to the soffit of
the landings.
