Smart glass, also known as electrochromic glass, is transforming modern office towers by providing dynamic tinting that adjusts to sunlight and temperature changes. When integrated with lighting control systems, smart glass offers fully automated control based on real time data, optimising building performance without manual intervention.

Through seamless integration, the lighting control system can automatically adjust the tinting of smart glass based on external light levels, internal temperatures, occupancy patterns and time of day settings. This not only reduces HVAC energy loads and operating costs, but also significantly improves occupant comfort by maintaining stable internal temperatures and minimising glare.

By allowing zone specific control and providing real time performance analytics, smart glass enhances tenant wellbeing, improves NABERS ratings and future proofs assets against evolving smart building standards.

How does it work? When an electrical charge is applied to the 5 ceramic layers on the glass, lithium ions charge which causes the layers to transfer making the glass tint; reversing the polarity then causes the glass to turn clear.

Prolux specialises in delivering end to end solutions for smart building upgrades, including design coordination and integration of the smart glass into the lighting control system and BMS.

Facility Managers play a crucial role in ensuring solar installations remain safe and efficient. Regular routine maintenance, clear isolation protocols and environmental considerations all play a part in preventing failures and reducing the risk of fire or costly system component replacements.

‘’Solar maintenance goes beyond cleaning panels.”

Take for example a recent fire within a solar inverter, located on the roof of a commercial office tower, which originated behind the DC protection cover.

This system was installed on a newly constructed building that had recently exited the Defects Liability Period (DLP).

Our investigation found that the MPPTs were overloaded with excessive current flow causing heat build-up. Poor electrical connections also led to high resistance and localised overheating, while exposure of the inverter to direct sunlight increased thermal stress on the system.

This incident highlights the importance of ongoing maintenance and regular system inspections.

Proper shutdown procedures should always be followed to prevent electrical hazards. Inverter placement should be carefully considered to reduce heat exposure and system configurations should be reviewed to prevent overloading.

Lighting control and building automation offer significant advantages, including improved energy efficiency, enhanced adaptability and smarter spaces that elevate functionality and comfort. However, most systems operate inefficiently due to outdated configurations or poor maintenance. Common issues like missing daylight harvesting, excessive sensor timeouts and improper scheduling can drive up energy costs, reduce equipment lifespan and create operational challenges.

Ensure your lighting levels are compliant to maintain a safe and productive environment for tenants, staff, and visitors.

Facility Managers know that a well-lit building is more than just a comfort; it's essential for safety and personal well-being.

According to Australian OH&S Standards, office lighting should range between 320-400 lux to support visual tasks and reduce eye strain while maintaining a safe environment. More complex, intricate tasks require greater levels of 500-1000 lux.

Insufficient lighting not only diminishes focus and productivity, but also increases safety risks, potentially leading to fatigue, long-term health issues and accidents in the workplace.

Prolux is equipped with calibrated lux testing equipment to test lighting levels, ensuring every area meets compliance.

Our team provides a thorough assessment and if any areas fall outside the required standard, we offer customised solutions to enhance illumination, whilst keeping energy efficiency and aesthetics in mind.

The correct lighting not only ensures compliance but also promotes positive well-being, creating an environment where people can thrive and perform to their best.

Weather stations provide real-time and forecast

data on wind speed, temperature, humidity and rainfall. This information is valuable for Building Management in deciding when to approve roof access permits to contractors for BMU, solar, telecommunication and HVAC maintenance.

When Facility Management raised concerns about contractor safety on roofs due to unexpected weather, Prolux provided a solution with the design and installation of a custom weather station. The data provided can be integrated into the Building Management System (BMS), with warning signs and strobe lights at the roofs access points, alerting contractors to unsafe weather conditions on the rooftop.

This system provides Building Management with real-time informative data to either limit roof access, restrict the duration of works, or stop any current works in progress, ensuring safety for all concerned.

Backup Diesel Generators are not only for emergency purposes, but can also have a secondary function of feeding power during peak periods or for heavy loads.

These generators are typically maintained quarterly and serviced annually. Quarterly maintenance includes inspecting both the fuel system and tanks, but fuel leaks can occur unexpectedly between these inspections.

Given that fuel tanks can hold thousands of litres, a significant leak poses a serious risk to a building’s operations. However, this risk can now be effectively managed.

Prolux identified this issue and have both designed and built a Diesel Leak Detection System. The system works via a float sensor being placed in a drip tray beneath the fuel system, which is connected to a custom-made controller. In the event of a fuel leak, the drip tray fills with diesel triggering the sensor and raises the alarm through an annunciator.

The Building Manager is alerted via an SMS, prompting immediate action. This controller can also integrate with the Building’s Management System, strobes and sirens and send out instant notifications to up to ten other telephone numbers.

Electricity distributor CitiPower has completed the first stage of works to one of Melbourne’s largest underground tunnels beneath Little Queen Street, which was originally built in the 1930s.

The upgrade will allow for a reliable power supply to cope with the city’s growing population, the demand on electricity now and in the coming years. The demand across the city is expected to increase by at least 60% over the next decade, growing from its current peak of 470MW to over 700 MW.

What is now set to follow is a larger three-year upgrade to the zone substation nearby. The upgrade is critical to the city’s economy for future growth and transitioning to cleaner energy.

Reports from the Australian Bureau of Statistics showed that in 2001 there were nearly 12,000 people living in the city, compared to over 40,000 in 2021. The increase in electric vehicles poses an increasing demand on the current system with almost 10% of all new vehicles sold being electric.

“Melbourne is growing and we are continuing to develop the infrastructure that is essential for powering our city into the future.”

C/O CitiPower Head of Network Planning Andrew Dinning.

Electrical circuits originating from switchboards must be identified in accordance with AS 3000 and AS 3439, including but not limited to the circuit rating and circuit destination.

When a new switchboard is installed and commissioned, the schedule outlining these details is affixed to the inside of the switchboard door. When circuits are added to a switchboard or circuit destinations are altered, the schedule needs to be updated accordingly. Unfortunately, over time hand written schedules can become illegible, outdated, or go missing all together. It’s a tedious, disruptive and expensive process identifying existing circuits and creating new schedules.

‘Fortunately, there is a solution with i-comply.’

Switchboard Management System i-comply allows electricians to scan a QR code located on the front of the switchboard to update schedules electronically. Facility Managers can simply login via the app to view the schedules and monitor updates at the touch of a button.

‘No more illegible or missing switchboard schedules.’

Prolux is currently rolling out this innovative software which will add value to your asset by improving efficiency and saving ongoing rectification costs, whilst adhering to the highest standards in building safety and compliance.

Maintaining your Solar Power System is a must to ensure ongoing optimum performance. Annual inspections including reporting for damage to the panel connections, wiring, inverters and isolators ensures that the safety and longevity of the system will not be compromised.

When water and dust mix repeatedly and dry on solar panels, mould and lichen growth is imminent. This build up restricts light absorption to the panels, compromising performance by up to 80%.

Prolux recommends including Solar Maintenance as part of your Planned Preventative Maintenance Schedule to maximise energy production and ensure safety assurance.

*Annual Solar Maintenance on a 20kw Solar PV System is approximately $600.00.

Air Circuit Breakers (ACBs) should be tested and serviced annually in line with the manufacturer’s guidelines and Australian Standards.

Replacement ACBs are not always readily available and preventative maintenance helps to identify when a replacement will be required – prior to a failure. Arrangements can be put in place to shut down a building and replace a faulty ACB at a convenient time, rather than doing so under non-ideal fault conditions.

Servicing ACBs is complex, requiring specialist technical expertise and costly injection test equipment. Prolux provides annual ACB testing as part of their Planned Preventative Maintenance Schedule, which includes both visual inspections for damage and deterioration and certified electrical testing.

Variable Speed Drives (VSDs) are commonly used in Commercial Towers to regulate the motor speed of HVAC units. This enables the adjustment of motor speed through the VSD, which allows for optimisation for either speed or torque based on demand. As a result of this, substantial energy savings can be achieved, along with the added benefits of reduced maintenance costs, waste, and noise reduction. However, it must be emphasised the importance of proper installation of VSDs, as an incorrect set-up can introduce Harmonics into the building's electrical system.

The electrical cables connected to VSDs differ from standard cables, in that they are shielded, featuring an outer layer of metallic shielding beneath the outer layer of insulation. It is crucial to ensure that when a cable enters a VSD and its isolator, the shielding is consistently connected through to the cable exiting the VSD and its isolator. This shielding also needs to be bonded to the VSD and its isolator uses specialised cable glands designed for this purpose. Failure to maintain this connection, either by breaking the shielding at the VSD or isolator or neglecting to bond it using the specialised glands, compromises power quality and introduces Harmonics into the entire building's electrical system, leading to unnecessary tripping of RCDs.

Prolux have observed many installations where the shielding is not grounded to the VSD or isolator, indicating an oversight or shortcut in the selection of appropriate cable glands during installation. A quick check of your VSDs can save thousands in the long run and ensure a more reliable electrical system without the risk of nuisance RCD tripping.

Ever heard of the saying ’poor man pays twice?’ In an ideal world, our expectations are met the first time. Making compromises usually means incurring higher costs in the long run. The same goes for the quality of power, the higher the quality of power, the lower the energy needed to operate the electrical equipment and in turn the lower the costs associated.

The good news is that effective management of Power Quality can lead to cost savings, a reduction in electricity consumption and prevent expensive equipment failures.

Conducting an on-site Power Quality Assessment enables the evaluation of a building’s power quality, to identify any primary causes, contributing factors leading to poor power quality and to allow for a plan of action to address any issues.

Prolux have completed many Power Quality Assessments, with a recent audit determining that simply by installing Power Factor Correction Units within their building would save the client over $9,000 in electricity costs and 12 tonnes of emissions annually.

A win-win for the client and sustainability.

Many CBD office towers have in excess of 70 combined lights installed across all Plant, Switch, Generator, Mechanical and Riser Rooms.

Due to the location and restricted access to these rooms, the control of the lighting is generally overlooked, with most lights operating 24/7. As these rooms are generally occupied less than 10% of the time, there is at least a 90% waste in electricity usage.

Timers and sensors controlling the lighting is generally non-compliant to AS/NZS 1680.2.4:1997 as the lighting can automatically switch off while the equipment in the rooms is being used or working.

To overcome this issue, Prolux recommended the installation of key operated light switches. The keys for the switches were retained by building security and signed out to contractors with keys to the plant room doors. The plant room keys could not be returned to building security unless they were removed from the lock on the light switch. The keys can only be removed with the light switch in the off position.

(AS/NZS 1690.2.4:2997 interior lighting industrial tasks and processes).

When charging lithium batteries there is always a potential risk in which they could undergo thermal runaway and in a worst case scenario combust into a self-sustaining fire, which is often difficult to extinguish.

With the growing popularity of electric scooters and electric bikes there has been a wave of reports identifying chargers overheating and causing fires. In Queensland, fire fighters are called to almost one fire event each week caused by lithium-ion battery faults.*

If nobody is present to remove the object and/or extinguish the fire, then there is an increased risk of damage to a building, especially when charging outlets are located indoors.

To mitigate this risk, Prolux put forward recommendations to install 4-hour push button timers on all e-bike and e-scooter charging outlets at a client's indoor EOT Facility.

Prevention is always priority.

Annual switchboard inspections and thermal scanning is a vital part of ensuring electrical safety and compliance. Many insurance agencies now have mandatory annual thermal scanning requirements as part of their insurance policies.

Prolux have trained and certified in-house thermal scanning technicians. As part of the inspection they check for thermal anomalies, faults and ensure switchboard safety and compliance is adhered to in line with the Australian Standard AS3000.

Upon completion of a commercial office building's switchboard audit, it was found that there was significant degradation of cable in just a seven month period. A shutdown was scheduled and the cable was changed over. This saved the client unplanned downtime and potential injury or harm to personnel.

Publicly available EV Chargers should be visually inspected by a trained technician every 12 months. This is to verify correct installation, running efficiency, identify any damage, wear and tear and to pinpoint any electrical faults.

Annual EV Charger Tests (as a minimum), should cover the following:

Proximity Pilot State (Current Simulation)
Control Pilot (Vehicle Load Simulation)
RCD Trip (Safety Switch Operation)

Prolux are equipped with the most advanced measuring instruments designed specifically for testing EV Charging Stations. Their tests will ensure the safety of your property and that all is adhered to and compliant.
