Electrical Services Section 20.00 / Page 1

20.00 Electrical Services

The requirements of this Section are generally Mandatory (Refer to Section 1.00)

20.01 General Requirements

This section outlines the University's minimum requirements for electrical services.

The layout of luminaires and power outlets should allow flexibility such that spaces can be

subdivided into separate areas.

Where island rooms exist, these shall be conduited to allow for the installation of power and

communication outlets from the relevant sub-board or Telecommunication Equipment Room

(TER) where these are not installed in the first instance.

20.02 Lighting

20.02.01 Performance Guidelines

All internal and external lighting shall be designed to enhance safe movement, personal safety

and security (CPTED), refer to Section 2.00 Planning & Design Controls. The following

lighting categories, in accordance with AS 1158.3.1 shall apply to the following nominated

external areas;

 Bus stops P6

 Areas adjacent to entry/exit (5m radius) P10

 General grounds used for night activity P7

 General grounds adjacent to areas used for night activity P8

 Entrapment spots P10

Internal areas shall be designed in accordance with AS 1680 and shall also incorporate the

requirements of AS 1428.

Lighting levels for each area shall be nominated by the Consultant or Contractor and submitted

for approval as part of Schematic Design. Over illumination is discouraged.

Particular areas nominated for specialised requirements will be identified by the user in the SDFs

and the appropriate lighting quality and levels recommended.

20.02.02 Design Requirements

Luminaires – All luminaires shall be manufactured from Australian made components where

possible and be approved by the Electricity Authority. All luminaires shall be supplied complete

with lamps and fused terminal blocks. Spring loaded ‘tombstone’ lamp holders shall not be used.

Single lamp luminaires generally shall be installed, however dual lamp luminaires may be used

where high ceilings occur or high lighting levels are required.

Fluorescent luminaires shall be of the high efficiency type incorporating high frequency warm/soft

start ‘Osram’, ‘Tridonic Atco’ or approved equal electronic ballasts, with a suitable controller as

outlined in Clause 20.03 of this Section.

All luminaires shall be adequately ventilated. Temperature rise in the fittings should be restricted

to 50

C above ambient.

Diffusers shall be integral to the luminaire and easily removable. All components shall be easily

accessible, with the luminaire in-situ. Fittings which have to be dismantled in order to replace

diffusers, lamps or tubes shall not be used.

Diffusers to T8 single lamp luminaires shall be;

 K12 diffuser for common areas

 K19 diffusers for offices, computer rooms and seminar rooms
