Design Guidelines & Procedures Version 18 ©
Electrical Services Section 20.00 / Page 4
Luminaires shall not be mounted above stairs and ramps or where access to the luminaires for
maintenance cannot be achieved in a safe manner without the need to use scaffolding.
Aisle stairs and ramps within rooms that have dimmable lighting, eg auditoriums, lecture theatres
and the like, shall be fitted with ‘Hawko H883’ extruded aluminium illuminated nosing strips to suit
the floor finish, incorporating white LED lamp sources at 100mm centres to comply with the
recommendations of AS 1680 and the BCA. This shall only apply if self illuminating nosings are
not used.
In non-enclosed stairs, or stairs where natural light is sufficient for day time use, stair lighting
shall be switched by the external lighting program of the CCMS.
Service/Plant Rooms – Luminaires in plant rooms shall be 2x36 watt T8 chain suspended
fittings with wire guards, located to provide maximum evenly distributed illumination, and shall be
IP rated where required.
Atriums – Lights shall not be located on the ceilings of Atria over 3m above f.f.l. Where the
ceiling height exceeds this limit, up-lighting mounted on walls or columns at not more than 3m
above f.f.l. shall be used.
Lighting Power Density - In general, the following maximum power density for lighting should
not be exceeded:
 General office, classroom 9 W/m²
 Corridors, storerooms 5 W/m²
 Toilets, stairway 3 W/m²
 Carpark, security 3 W/m²
20.03 Lighting Control
20.03.01 General Requirements
To keep the energy consumption of artificial illumination to its absolute minimum and to reduce
waste by increasing lamp life cycles, effective lighting control systems shall be employed.
Lighting control throughout buildings shall implement strategies that take advantage of available
daylight and monitors usage of the area and adjusts lighting levels accordingly.
Lighting controls shall be interfaced with other systems such as the AMX audiovisual and CCMS
systems where required by the project Technical Brief.
It is crucial that natural light is integrated with lighting control systems to control the amount of
artificial lighting required. Automatic stepless dimming control shall be employed. The system
shall be extended to all areas of the building except where noted otherwise in this Section.
Local manual switches shall control plant rooms and service riser luminaires.
Lighting of external areas shall be controlled via the CCMS utilising a sunrise/sunset feature
integrated with a PE cell override for cloudy days. A manual override switch shall be provided in
the local distribution board for maintenance purposes. Note: Some projects will require additional
control groups.
Motion/light level detectors shall be surface or flush mounted on the ceiling, and spaced at the
most effective distance. Mechanical switches shall be installed to activate the motion/light level
detector and the room light fittings.
Switches shall be located on permanent walls or columns wherever possible, at 1 metre above
the finished floor level. All switch plates shall be identified with type written labels with black
lettering as to circuit and switchboard of origin. Light switches shall be rocker type ‘Clipsal
C2000’ series with I.D. covers secured with j-screw mechanism located behind the switchplate.
Submit details of the system configuration and programming for approval by the GU Electrical
Engineer.
