INTRODUCTION

The purpose of this brief is to set out RMIT University's minimum requirements for the design of electrical services. The aim is to achieve the maximum possible consistency and standardisation across the electrical services systems on the RMIT University campus. Any design aspects not specifically addressed by this brief shall be identified by the consultant during the design process and shall be brought to RMIT University's attention for resolution. It is expected the installation of electrical services and equipment in the buildings associated with the project shall comply with all current statutory requirements and current Australian Standards; hence these are not specifically referenced as part of this document. In all instances the design shall be carried out in accordance with the latest edition of AS3000 and the service and installation rules. For the purpose of this design brief, whenever reference is made to RMIT and/or RMIT University it shall be understood to mean the RMIT University Services Project Manager or RMIT University's nominated representative for the project. In all instances the electrical services shall be designed in consultation with the designated RMIT representative.

6.2

SCOPE OF WORKS

The scope of works for the electrical services is defined on a project by project basis in a separate consulting agreement document which is to be read in conjunction with this brief. Note that this brief generally covers works associated with electrical services only. For further details on the communications systems see Section 10 of this brief.

6.3

POWER SUPPLY

The electrical supply distribution system for the campuses 3 phase, 4 wire 240/415 volts, 50Hz. However, the consultant should be aware of the intended future standardization of the power supply to 230/400 volts, 50Hz and this should be taken into consideration in the design of the electrical services. The supply originates from Supply Authority sub-stations distributed around the campus. Early in the design stage, the consultant in consultation with RMIT shall: Evaluate the anticipated Maximum Demand (MD) and energy consumption for the project; Liaise with Supply Authorities representatives as required; Recommend the selection of the appropriate tariff (for separately metered installations). Recommend the appropriate load and energy management techniques.

The consultant shall prepare and submit to RMIT a pre design report for addressing the issued nominated above.

6.4

CONSUMER MAINS

Consumer mains shall be designed to accommodate 125% of the anticipated maximum demand as determined in consultation with RMIT and the Supply Authority. Computation of the anticipated voltage drop shall be based on the 125% of the anticipated maximum demand.

6.5

POWER FACTOR

Electrical services equipment installed in the building shall maintain a power factor of note less than 0.9 lagging. Where the installed equipment is found to be less than 0.9 lagging, the contractor will be required to implement all necessary rectifications with no variation to the contract and at no cost to RMIT. However, some mechanical services equipment may have an undesired effect on the power factor of the overall system. For these situations, the consultant shall consider and make recommendations for the use of power factor correction equipment as required to achieve the desired overall power factors for the installation. Power factor correction equipment shall generally be located as close as possible to the source of the power factor in need of correction. However, the finally location shall be determined in consultation with RMIT. The manufacturer and the type of power factor correction equipment shall be specified to RMIT's approval. As part of the design process it is required that the consultant investigate and advise RMIT on the benefits of aiming for an overall power factor higher than 0.9 lagging and shall make appropriate recommendations.

Design Standards Brief Section 6 Page 12 Issue No. 6, 2009

©Copyright | RMIT University, Melbourne, Australia 1997 | ALL RIGHTS RESERVED

Section 6 ­ Electrical Services

These asset numbers will form a data base to be shared with the Building Automation System (BAS) field device tag numbers and used for the purpose of asset management and maintenance. The asset number is made up by the following numbers separated by dash: A 5 digit number consisting of 3 digit number to identify the building number combined with a 2 digit number to identify the floor or level number. A 3 digit number to identify the zone or room number. Three character alpha code to identify the device ­ refer to the list of alpha codes for RMIT equipment detailed in the attached table. A number consisting of 3 digit maximum with no leading zeros to identify the number of the specific device located in a given zone or a room.

For example, asset number 01014-101-CWP-1 identifies the only chilled water pump on level 14 of building 10 in zone 101. All assets shall be provided with an asset number label which shall comprise of a Gravoply or equal, engraved on a white background to display the asset number. A bar code representing the asset number shall also be suitably affixed to the label below the engraved number. This will facilitate the device data to be electronically retrieved from the RMIT Asset and Tag Number Data Base by means of a hand held scanner as required. The asset label shall be provided with a suitable adhesive backing that will make it impossible to remove from its location unless it is physically destroyed.

C. BAS Field Device Tag Numbering and Labelling

In addition to the above, RMIT require to separately identify each item of equipment that makes up the BAS system.

INTERNAL LIGHTING CONTROLS

General

It is the RMIT's main aim to actively seek to implement energy and cost efficient lighting systems. As a minimum all lighting designs shall comply and be certified to the requirements of BCA Part J6. The following lighting control systems have been identified for further evaluation and recommendation. Option 1 - Dali ballasts to all light fittings for connection to a lighting control system for full monitoring of fitting status for maintenance plus daylight and light depreciation compensation. Movement sensors also to be connected. Option 2 - Dali ballasts without connection to a lighting control system but daylight and light depreciation compensation. Movement sensors also to be connected. Option 3 - Controls to provide daylight and light depreciation compensation. Movement sensors also to be connected. Option 4 - 240 Volt controls wiring with sensors in fittings for daylight compensation only. Acoustic / movement sensors also to be connected. Therefore, the consultant shall investigate and shall report to RMIT regarding the lighting control systems most appropriate for the project and shall detail: Options available Advantages and disadvantages Cost benefits Potential running cost savings Budget estimates

However, as a minimum the following requirements would be applicable: Light fittings located near windows shall be grouped to a separately switched circuit; In all other areas, control shall be circuited to alternate luminaires; Security lighting shall generally be provided at corridors and intersections. In large open areas, spacing should be at every 25 m. The number of light fittings on security lighting shall be no more than 5% of the total number of light fittings; Dimming and/or time switch controls for the dot point items i and ii above shall be provided as appropriate to the requirements of part J of the BCA. Plant rooms, corridors, foyers, lobbies and other service areas control shall also be circuited to alternate luminaires; For stair lighting one circuit shall be provided for luminaires located on each main landing and a separated circuit for luminaires located on each intermediate landing; Time switching for corridors, toilets, foyers and lobbies shall be to approval and shall be compliant with BCA, Part J6;

Section 6 ­ Electrical Services

Time switching, manual switching and occupant sensor switching for office areas, lecture theatres, libraries and classrooms shall be implemented as per BCA, Part J6 regulations. In general, the entire lighting control system shall be in compliance with the requirements of the current BCA, Part J6 regulations. The design of lighting controls shall be such that lighting is manual switched on, but auto off in single office, meeting room areas and other applicable areas.

6.12.2

Light Switches

Light switches shall generally be provided as follows: Grouped to service functional areas relevant to the building occupation; Individual small to medium rooms e.g. offices, stores etc.; Where four or more switches are located adjacent to each other, they shall be ganged under a common stainless steel plate.

6.12.3

Lighting Motion Sensors

For rooms and/or areas anticipated to be occupied infrequently, lighting shall be controlled by lighting motion sensors. Sensor locations and quantum shall be determined to ensure complete coverage of the corresponding area. Lighting sensors for amenities areas shall be of dual acoustic type. Lighting motion sensors shall be provided with an isolator/lighting switch located to the main entry door to the room. Lighting sensors shall comply with the requirements of part J of the BCA.

6.13

EMERGENCY LIGHTING AND EXIT SIGNS

Emergency lighting and pictograph exit signs shall be provided throughout the buildings in accordance with the requirements of AS2293 and BCA Part J6. For situations where only part of the floor area is affected by the project works, the design of the emergency lighting system shall consider the entire floor area for compliance. Particular emphasis shall be the path of escape to fire escape stairs, within the stairs and to the final exit. Emergency luminaires and exit signs shall be the LEGRAND Minitronics Monitored Commander System type. Where possible, no Single Point Units are to be used due to the difficulty in testing. (Note: The Commander fitting can be tested Single Point where a computerised monitoring system has not been installed). Emergency exit signs shall be of the pictograph type and illuminated by an LED light source for both emergency and 240 V operation. Sustained emergency luminaires shall not be used. i.e., emergency luminaires shall not be used for normal lighting. All exit signs shall be installed at a minimum of 2200 mm above floor level to the bottom of the luminaires. All luminaires shall be suitable for termination to an automatic computerised maintenance system. RMIT currently utilise a Minitronics central computerised system.
