We are proud of the projects that we have completed recently. Our approach is that anything is possible. We welcome the opportunity to discuss your next project with you.
H&D Electrical was assigned the task to design the LED lighting to the Porsche showroom through our valued customer AP Eagers. The main focuses for the new showroom lighting was to decrease maintenance costs, decrease electricity costs and to better improve the level of lighting on the prestige vehicles.
H&D Electrical lighting project designer carried out Lumen LUX level testing of the existing lighting to help understand how the lighting could be improved and to identify what specification of type of light is required for the new installation.
The test results indicated that LED track lighting design was required to capture the correct beam angle of light to project effectively down on to the showroom vehicles. The LED track lights that suited the specification was a lighting system designed in Switzerland by an international leading lighting brand.
Our Project Technician completed the installation by using a fully automated Philips Dynalite control system; the LED track lighting was completed with dimmable components to achieve the perfect Lux beam lighting level for the showroom. The power and maintenance saving cost was very impressive and calculated to be $15,000 annually compared to the existing metal halide lighting system.
HDE specialise in architectural fitout designs, primarily in Bank, Retail and Office environments, that have detailed drawings of lighting, power and communication equipment. We have had the privilege working with our valued customer QT Mutual Bank (QTMB) for 30 years. HDE has helped QTMB design and install electrical, communication and security for the roll out of 12 new branch fitouts Queensland wide.
HDE has developed a great understanding with design, organisation skills and scheduled planning to help with tight time frames whilst still producing high quality work. Some of the branches were refurbed in short time frames of only two weeks from start to finish.
Lighting design was produced by some of the leading lighting manufacturers and completely automated with ECS controls to come on with trading hours and diming to suit light levels to blend the layout to the perfect lumen lux level.
Power design was automated using C-Bus controls, gaining ultimate energy saving with detailed programming turning off monitors and appliances during afterhours calculating into savings of up to $10,000 annually off our client’s electricity bill.
Communication and security has been designed with the latest Krone Cat6A cabling to suit the high-speed operations of the branches, producing high speed of data rate at 10Gbps. The security was installed with the latest high quality IP camera DVR system and hold up system cabling to comply with our client’s high standard insurance inspections.
HDE has also scheduled maintenance every 6 months to the QTMB branches to maintain the electrical and safety compliance by conducting emergency light testing, RCD testing and analysing and checking all automated functions are working correctly to maintain the quality of the fitout and increasing the infrastructure life expectancy of the branches.
The building at 100 Creek Street, has two transformer supplies from the supply authority. Transformer one is running at a 1.00PF and does not require any correction. Transformer two is running at a 0.92PF and does require correction as there is large amount of inductive load present causing poor PF.
Unit to be installed in MSB room on ground level. We have opted to use the Sinexcel SVG PFC unit which uses internal IGBT’s by using pulse width modulation signals to make the inverter produce the exact reverse reactive current of the corresponding load reactive content. The Sinexcel is a superior unit as it reaches above and beyond when correcting PF and extinguishing loses of power from harmonics as well. The unit will also require very little maintenance increasing speed of project ROI. As the calculations show, the building owner will be saving an estimate of $30,000 per year and a reduction in CO2 Emission of 8.69 tonnes per year.
An electrical load with a poor power factor draws more current than a load with an improved power factor for the same amount of useful power transferred and can put unnecessary strain on the electricity distribution network. By improving your power factor, you can reduce your electricity bills through lower monthly demand and capacity charges. Typically, payback periods for power factor correction are between 1-3 years. Given the life expectancy of power factor correction equipment and the potential savings, it can be a very worthwhile investment.
Poor power factor may cause power losses and voltage drops, which can contribute to overheating and failure of motors and other equipment. If your electrical system is near capacity, installation of power factor correction equipment may help avoid costly infrastructure upgrades by lowering the existing electrical demand on your system and improving efficiency stability.
One of our long term clients owns and operates a factory specialising in bench top design, fabrication, modification and supply to tradespeople and the general public. One of their many challenges on a day to day basis was the transfer and handling of their customised bench tops to different machines within the factory. Pieces were often moved by hand to each of the different stages of the production process. This manual labour not only placed undue strain on their employees, but also caused a loss in productivity as moving the products was time-consuming and tedious.
ABS came to us with an idea to automate the transfer process, not only to lessen the stress on their employees, but also to prevent any damage to the final finish of the products and most importantly saving our client in labour cost by increasing productivity by thirty percent.
HDE designed, supplied and installed a programmable Alpha PLC logic system catered to their specific needs and production schedules. This new and completely customised system made use of intelligent and up-to-date hardware manufactured by leading worldwide brand SICK, such as sensors designed specifically to identify each bench top finish type. Simplified control panels made production much easier by making start-to-finish production possible with the push of a single button. The system was designed to speed up and maintain a higher pace of production, regardless of the dimensional request of the products.
The existing T8 fluorescent lighting in the basement car park levels and plantrooms throughout 515 St Paul’s Terrace, stay on for approximately 12hrs in basement and 2hrs in the plant room per day. Fittings are twin 36w fluorescent battens with electrical usage of 72watts.
The Facility Manager sought our recommendation for lighting upgrade options when a large percentage of the T8 lights were failing from faulty blown lamps and ballast. The Manager was looking for a solution with a longer life span than the average two years for the T8 lighting Battens, thereby reducing lamp replacement and maintenance costs.
Our Project team provided the building owner a full calculation for the retrofit, providing ROI comparisons using forward lifecycle and maintenance forecasts with improved energy consumption profiles.
HDE suggested to use Prolume fittings as we had recently retrofitted 340 Adelaide Street and the Citilink Building in Brisbane. The Prolume light’s integral microwave motion sensor instantly switches the light from standby light output (eight watts) to full light (35 watts) on detection of movement in the space. After a set period of time (15 seconds to five minutes), the light returns to standby mode. Prolume offer other models that sensor to off or just stay on constantly until switched off by control. The reason for 3 different types is so that installation of Prolume meet requirements of Lux light output due to safety standards and save maximum power.
The carparks will have all 3 different types of Prolume light Battens as mentioned above and have been installed and mapped out and calculated to require lux levels.
