Public Realm Framework - Section 2.12 and 2.13

Subsection 12 relates to banners and flagpoles, and subsection 13 covers street lighting.

2.12 Banners and Flagpoles

Banners and Flagpoles will be assessed on a needs basis.

2.13 Street Lighting

Design Principles

A consistent approach to lighting within the Central Geelong Area is an important part of realising the objectives of the P.R.F.

An approach that focusses on well-lit public roads and spaces to facilitate activity and public safety is the goal of this guide. Importantly this should not result in an overly-lit environment but rather a nuanced and holistic lighting strategy ultimately providing users with an enjoyable and safe nighttime experience.

Express ‘spill’ from lighting in any direction should be avoided as should glare as well as excessive contrast between lit and unlit areas. A lighting philosophy focusses on the beneficial eff ects of lighting rather than light fittings should be pursued in all public realm installations.

A three tier hierarchy of lighting is proposed to cover the general range of lighting types:

Street Lighting
Pedestrian Lighting
Custom Lighting Application

Street Lighting Street lighting should be determined by the application location and road lighting category required. Relevant authorities should be consulted where responsible for lighting and pole assets prior to any installations. Continuation of preferred asset ownership should be sought as CoGG have recently taken an ownership of some lighting infrastructure in the central Geelong Area.
Pedestrian Lighting Pedestrian level lighting has the function of providing illumination to higher intensity activity areas where after hours use is being actively promoted. Pedestrian safety including sufficient lighting for effective CCTV operation is equally important and design for this tier of lighting should support this function.
Custom Lighting Application Custom lighting applications depend largely on the broader project aspirations and the location. Examples include:

Architectural feature lighting
Artwork/sculptural illumination
Interactive lighting
Tree uplighting
Illumination of landscape / streetscape features

These three levels of lighting should be explored and coordinated holistically in a project’s lighting design to achieve an efficient and site responsive illumination of the public realm.

Design Principles

The following guiding principles from the basis of the basis of P.R.F. recommendations:

This P.R.F. proposes the use of White Light only and recommends the ultimate removal of all orange HPS and pale blue MV light sources in the project scope area.
The required lighting technical performance criteria for each space in terms of compliance with AS1158 are outlines; all are based on the V Category (Vehicular traffic) recommendations within AS:1158.1.1 AS1158:1.2 and P Category (pedestrian) recommendations within AS1158.3.1.
The variation of lighting levels commensurate with the above and also public safety visual guidance and night-time focus is outlines.
Luminaires to be NEM 7PIN compatible
The lighting of vertical surfaces (building facades) in a systematic and consistent manner coordinated with the requirements for City of Greater Geelong.
A plan for the considered use of light colour temperature as a means of adding variety to the night-time vista is presented.
The placement of ‘one-off ’ lighting features as visual drawcards and place-makers is supported.
A set of benchmark luminaire types and mounting heights is proposed.
A hierarchy plan for luminaire mounting heights is proposed.

V Category Lighting

The principal design objectives within AS1158.1 for Category V lighting are to provide the following:

Luminance and luminance uniformity of the carriageway surface to a specified level.

Glare control to a specified level.
Illuminance on intersections carriageway verges and other nominated locations to a specified level.
Limitation of upward light from luminaries to a specified level.
A maintenance regime such that the lighting scheme complies at all times during each maintenance cycle over the life of an installation.
Minimising energy consumption.

The differences between V Category and P Category lighting are fundamentally the following:

V Category is primarily concerned with the carriageway luminance (essentially surface brightness) which is a different concept than illuminance (lux) and is also position dependent (that is: taken from the driver’s point of view)
V Category only takes illuminance into account at intersections verges and the like – in other words places where pedestrians might exist.

Lighting Standard

Poles

Height: To be confirmed by lighting designer for given project

Format: Tapered round pole with minimal cross-section to meet structural requirements. Frangible where deemed necessary by traffic engineer but otherwise non-frangible construction.

Footings: Structural engineer by location. All structural connections (for example: gusset plate) to be set below finished pavements.

Access: Secure flush finish access match at base of pole. Service pit ≤ 1m from base of pole with connections to pole.

Colour: To be confirmed

Colour temperature: To Australian standards generally close to daylight. All lighting selections to be made as part of custom lighting design by qualified electrical engineer or lighting designer.

Luminaire: Model to be confirmed with council officer by application and location.

Street level

High performance efficiency LED IP65 rated fixtures. All street lights to have integrated NEMA sockets for example: Aldridge Aero V-led or Bega 99599 pole top luminaire. Colour to be confirmed generally to match poles.

Pedestrian level

High performance efficiency LED IP65 rated fixtures for example: Bega 99446 pole top luminaire or WE-EF FLC 141 pole mounted luminaire.

Colour temperature: typ. 3000K

Note: Models listed are generic only and do not provide specific output or model details.

Custom applications: Type format and arrangement will diff er by project and location. Tree uplights luminaires should be specified with all housing and controls required to install as per manufacturer’s specifications. Lights should have internal angle adjustment for fine tuning of illuminated area for example: Bega 77133 or WE-EF ETC320-FS LED. Uplight luminaires should have colour change (RGBW) capability and data cabling run back to the switchboard.
