2.11.3 Energy Use
In order to align with RMIT’s Energy Management policies, power consumption of all active devices must be
considered when selecting appropriate technologies. Power ratings when operating, low power, sleep and off
modes will be used in order to select the most energy-efficient component.
The Integrator must ensure correct operation of equipment when selecting efficiency mode.
Section 4 RMIT Design Standards - Energy Management provides further general information regarding the
policy and its application to building services design. More information is available on the RMIT Property
Services website.
2.12 Cabling
2.12.1 Manufacturer's Recommendations
Install, terminate and join cables in accordance with the manufacturer's recommendations.
2.12.2 Drawing and Handling Cables
Ensure that cables do not exceed the manufacturer’s specified pulling tension when drawing cables.
2.12.3 Joins
Cables shall be run without junctions or joins except where prohibited by site conditions. The number of
termination points along a single signal path shall be kept to a minimum and must always be less than the
stipulated limit of termination points or junctions.
2.12.4 Installation
Cables shall be concealed wherever possible unless specified otherwise. Cables shall be run in the shortest
practical route, in a manner causing the least strain and be supported using conduit or duct and cable tray
where necessary. The least preferred method of cable support is catenary wires or hangers.
Proposed cable routes and installation methods are generally shown on the drawings and/or described in the
specification. Where a more suitable route is found the approval of the Principal shall be required.
Provide any cable ties, hangers, trays and other cabling management equipment required to ensure that there
is no strain on cables or connectors. Provide draw wires in all ducts to allow for accessibility and ease of
operation if unused. Keep all cable access hatches and openings free and clear of dirt and debris. Provide
adequate protection of cable ends from damage during installation. Where minimum segregation cannot be
achieved, AV cabling is to be run in continuous earthed metal ducting/conduits separate from AC power cable.
Speaker level audio, line level audio, (low level) microphone audio, video, control, extra low voltage power and
data cables shall be suitably segregated from each other so that EMI is minimised. All cable runs shall be
neatly laced, dressed and adequately supported. Cable bundles shall be tied using approved cable fasteners
such as Velcro straps. Plastic cable ties must not be used for looming.
