I-Light is designed to gather energy from the sun via solar panels, this energy is then stored in battery packs, as the daylight diminishes the lights are activated automatically and will run on stored energy from the battery pack.
At a designated state of charge a signal is sent to start a single cylinder diesel engine coupled to a 24v alternator, the engine will start and bring battery charge up to a designated point then turn off, with good sunlight this operation will normally only occur once per night, in adverse conditions twice per night, as the sun comes up the lights will turn off automatically and start the process again.
The lights used are LED fixture with directional cones around each LED, this allows for the lights to be extended further out than the common LED fitting currently available.
Each light tower will reduce costs by 30-40 percent against traditional style light towers and reduce CO2 emissions by approx 50 tonnes per year per light tower.The lights reduce the need for heavy and light vehicle interaction in mining pits.
Company: Lunagas
Project: Predictor of coal mine gas quantity emission from abandoned coal mines
Location: Merewether, New South Wales
Lunagas developed a PC based computer software Coal Mine Goaf Gas Predictor (CMGGP), which can be used to predict the initial gas quantity and the decline trend from abandoned and/or closed coal mines.
Gassy mines emit approximately 80,000 tonnes of pure methane to the atmosphere per annum.
Only a small percentage of that methane has been utilised, due to uncertainties regarding individual mine methane quantities, quality and period of life-time available for coal mine methane utilisation.
Energy companies and/or city councils find the program useful for determining methods to better utilise the majority of coal mine gases in order to protect the environment from harmful gasses discharged from abandoned/closed mines.
In addition to achieving the additional sources of energy such as electricity and/or heat generation for old, existing and planned for closing gassy coal mines.
There are more than 1,5000 closed coal mines in New South Wales from which 40 are gassy and active.
Company: AZZO Automation
Project: Desert Knowledge Australia Solar Centre and associated projects
Location: Alice Springs, Northern Territory
The project the Desert Knowledge Australia Solar Centre (DKASC) is a demonstration facility for commercialised solar technologies.
The DKASC was developed by CAT Projects and Desert Knowledge Australia, as a resource for the rapidly expanding solar industry globally, and in Australia in particular.
The Solar Centre promotes understanding and confidence in the complete range of current solar technologies, and provides the industry with long term system level data proving the reliability and performance of solar power generation in various conditions.
A priority of the system was the accurate and reliable monitoring of each solar array.
AZZO Automation designed and commissioned the energy management system and weather station data acquisition, using Schneider Electric PowerLogic ION meters and ION Enterprise software interfacing with a customised advanced datalogger.
AZZO Automation has pushed the PowerLogic ION technology as far as it can go utilising any and every capability of the hardware and software, from reporting to device mastering and custom dashboards.
All of the information is remotely logged with full data caching, transmitted to an externally hosted database, and is linked in real-time to a flash-based website which is used both on-site and remotely for analysis.
Company: Horiso
Project: Horiso Dynamic Façade Controller
Horiso is a solar blinds-manufacturer which developed the first Climate Ready Dynamic Façade. The Horiso Dynamic Façade Controller uses BACnet* protocols which ensure easy integration with all other building management system.
Such systems can be combined and remotely controlled and monitored from any location with a unique Graphic User Interface (GUI).
With the shades automatically adjusted by the SAI software, there is immediate comfort of maximum light with no glare in a perfectly-controlled environment.
With the right shading device, this equates to a 93 per cent reduction in solar transmission and a cooling cost reduction of up to 69 per cent, depending on the configuration of the building.
Tracking and calculating the Sun’s Angle of Incidence (SAI)* in combination with new shading-device technologies has significantly reduced the energy footprint of buildings.
By integrating intelligent-control of the façade’s louvers and sun-shades into the building-management system, microprocessors ensure each shade and louver adjusts individually according to the angle of the sun ensuring the exact position required to achieve maximum heat and light control.

The solar lights run at 25%, until wanted to deliver the full 200 lumen lights levels focus on where it is needed such as pathways, signs or seats.
The ‘walks smart with you’ aspect is automatically managed from software analysis of the built-in board camera video sources.This determines speed of pedestrians pushing a pram, walking the dog or bike riding; this makes these LEDS and the next lights brighter.
As the unit is designed for long life, maintenance-free application, there are 4 unseen PV arrays on the top, 3 long life battery sets in the pole.
The 24 x 50,000 hour LEDS are in 4 clusters and an optional low voltage connection to the next poles is part of the power management, so that tree growth and seasonal sun changes have minimal effect.
The remote overall automated management uses the onboard cell phone system, including GPS, so if the unit is stolen, this is instantly detected and tracked.
Company: K.E. Brown Electrical Switchboards
Project name: Darling Walk redevelopment
Location: Darling Harbour, Sydney
K.E. Brown (KEB) Electrical Switchboards was involved in a $560 million Darling Walk regeneration project in Sydney’s Darling Harbour.
The project compromises two commercial buildings, with Commonwealth Bank of Australia taking all office space of levels 1 to 8 in both buildings.
It will lead the rejuvenation of Darling Harbour’s southern precinct and further activate and improve Sydney’s CBD.
KEB supplied all the switchboards on the project, including leading communications, electrical Data and HVAC services supplier Fredon.
This was responsible for the complete electrical installation for the project, from the base fit-out to the subsequent integration and fit-out of all 16 floors.
Whilst conserving energy, the KEB design also recognises the electrical distribution systems of environmentally sensitive commercial and industrial buildings become more complex.
Company: Aurecon
Project: Turbine And Boiler Safety Integrity Levels Study AGL Torrens Island Power Station
Location: Torrens Island, South Australia
The project involved Aurecon providing risk analysis services to AGL Torrens Island Power Station to assess the required Safety Integrity Levels (SIL) per AS 61508 for the required protective shutdown functions on their boiler and turbine plant.
Previous SIL assessments had been carried out for the plant under review. AGL identified that the associated documentation did not fully meet the Safety Lifecycle requirements of AS 61508.
Aurecon’s solution and service methodology was based on a comprehensive build up of the required documentation framework from first principles. The outcomes of the project provided the first step in reducing AGL’s risk of a significant safety incident.
Aurecon’s technical rigour and collaborative approach with the client has led to an outcome that provides a strong foundation for the upgrade of the burner management systems at AGL.
AGL can now be confident that they comply with AS 61508, resulting in improved safety for their plant once the upgrade is complete. As well as delivering on safety, Aurecon have applied their advanced engineering knowledge and experience to maximise the availability of the plant without compromising on safety.
