What is the difference between Static Shock and Electric Shock?
Over the past hundred years, electricity has evolved and adapted into a necessity which society cannot live without. We have become quite dependent on its uses; making it hard to escape, from flicking the kettle on in the morning to the powerful yet beautiful strikes of lightning during a storm.
Put simply, electricity is made through the burning of fuel. Australia uses either coal or a natural gas, which is burnt to heat water and create steam. This turns a turbine generating electricity, then travelling along the conductor wires, which we call powerlines, to the specified destination.
Although electricity is used every day, it can sometimes be harmful but also fun – being the core ‘ingredient’ to some experiments.
Static Shock
Static electricity, also known as electrical energy at rest, is the build-up of electric charge on a material. This charge is usually built up through friction, which is the contact between two objects which are both insulators.
One of the most common science tricks to create static shock is to rub a balloon against your hair, making your hair stand up on its ends.
Another example is to rub your rubber-soled shoes against the carpet and then touching a metal door knob, giving you a ZAP!
These things happen due to an imbalance in electrons in both objects, with one losing their electrons, creating a positive charge and the other gaining electrons, creating a negative charge.
A static shock isn’t harmful; it may be uncomfortable and cause a bit of a fright to the receiving personnel.
Electric Shock
An electric shock is the sudden discharge of an electrical current from an electrical source, like a power point, which has enough force to pass through a human body part. This electrical energy flows through the human body part, creating a shock type feeling which can cause little to no injury or can be life threatening.
There are some different ways which you can experience an electrical shock, including; faulty appliances, power points, damaged electrical cords, electrical appliances and water coming into contact, incorrect household electrical wiring, and also a lightning strike.
Electrical shock can have little external evidence that it has occurred, however the internal effects of receiving an electrical shock could be life threatening.
An electrical shock can cause burns, tingling, numbness, nerve damage, and even cardiovascular problems. Seeking advice from a health care professional is always advised after receiving an electrical shock, even if you feel ok.
The main difference between these two different but similar shocks, are the outcomes and the way which they are created.
Static shock is created through human effort and electrical shock is created through electrical means.
Static shock doesn’t give a harmful result and electrical shock can cause no to life threatening results.
The Effects of Natural Lighting vs Artificial Lighting
Light is emitted via two different sources – natural and artificial. The sun is the primary source of natural light, while light globes are the primary source of artificial light. There has long been an awareness about the effects that lighting has on the human body, and now science is alerting us to the vast impact that light has on our physiological, psychological and emotional wellbeing.
So `when choosing how to light your home or office, a lot of consideration needs to be put into it. To stay healthy, alert and productive, people need to have regular circadian rhythms and keep to a constant sleep/wake cycle as directed by our exposure to certain light wavelengths during the day.
How does light affect us?
There are two key hormones that are affected by light – the sleep hormone melatonin and the stress hormone cortisol. When waking up in the morning, it’s important that our bodies produce enough cortisol to promote alertness. Into the evening and towards sleep, people need to stop the production of cortisol and begin producing melatonin.
To do this, the body needs access to bright light with blue wavelengths in the first few hours of waking up. Brightness and intensity may be decreased throughout the day and by night, blue light must be eliminated and amber tones, increased. By the time we head towards sleep, we should eliminate light altogether.
Human’s have evolved to use the sun’s light to dictate their sleep/wake cycle, so correct lighting design for daily living and health is about mimicking sunlight. This means that careful attention must be paid to colour temperature and light intensity.
In fact, our reliance on light is so intense that during the darker months of winter, many people can experience Seasonal Affective Disorder. As the mornings are much darker during the colder months, we do not experience as much intense blue-rich light in the mornings, affecting our cortisone levels. This can make us feel less alert and less vibrant, which can sometimes evolve into a depressive state.
There is some concern that the excessive use of smartphones and tablets in the late evenings can affect sleep quality because they emit substaintial amounts of blue/green light at the wavelengths that inhibit the release of melatonin, preventing us from becoming drowsy. Poor quality sleep has been linked with increased risk of obesity, diabetes and heart disease.
Blue light can have a major effect on your sleep.
Natural Light
Natural light is full spectrum, meaning that it contains all colours of the rainbow, as well as colours (wavelengths) that we cannot see, such as infrared and ultraviolet. Without all of these colours, our world around us would look a lot more dull, as we wouldnt be able to see skintones or textures, for example, in their full glory.
Natural light is also dynamic, meaning that the intensity and colours of light change with the time of the day, time of the year, weather and location.
Our mood, energy, metabolism, sleep and recovery all depends upon the daily cycles of natural light, since these changes synchronise our circadian rhythm and hormone cycles. When the sun is overhead, daylight is bright and rich in blue (which stimulates us), while at sunset, daylight softens and is dominated by red (which relaxes us). These changes are due to atmospheric filtering of sunlight, which changes with the angle of the sun. Humans, plants and animals depend on these daily and seasonal cycles of natural light for their health and wellness.
The benefits of natural light are extensive:
Day-light increases our productivity and comfort.
Access to natural light improves one’s circadian rhythms.
Working in daylight boosts mood and motivation leading to the work is done faster, creating more pleasure and essentially better results.
It creates a calmer indoor environment, reducing one’s stress.
Utilising natural light reduces reliance on electricity and therefore reducing electricity bills.
Studying in natural daylight reduces stress and has been shown to improve student performance.
Artificial Light
Artificial light is used as the substitute when there is an insufficient amount of natural light, with a similar concept as natural light. Artificial light is composed of visible and invisible radiations like ultraviolet (UV) and infrared (IR).
Artificial light can come in a variety of different colours and intensities, depending on the environments mood.
The UV and IR radiations which artificial light sources hold aren’t harmful to the health of humans, as long as they aren’t situated at a close range or extremely intense. Think of it like this – the annual dose of UV from artificial light is equal to a one-week holiday in an overly sunny destination like the Sunshine Coast.
Although artificial light isn’t harmful most of the time, it has some aspects which can essentially create some health risks.
The blue light aspect of artificial light can have a deeming effect on one’s internal body clock, along with the hormonal system which can lead to overall health problems relating to sleep deprivation and stress. The body’s internal body clock runs on dark and light, and the different chemicals in the brain to let us know ‘when its time to get up and when its time to go to sleep’. These chemicals are then affected by the artificial light which is being used. The blue light in smart phones is the perfect example; when used in a dark room before sleeping, the production of melatonin is reduced, making us less sleepy and more likely to stay awake. If this is a reoccurring situation – sleep deprivation can quickly become a major health problem.
UV light is also a harmful ingredient in both sunlight and artificial light with excessive exposure. UV is what creates the tan on the outermost layer of the skin, but skin cancer can become a quick health problem if too many skin cells become harmed in the process. With tanning beds are a popular way to create this tan, the large amount of UV light which is used can have a major effect on one’s skin and even create eye damage.
Sun baking in tanning beds can cause skin cancer.

What To Choose? Ducted Air Conditioners vs Split Air Conditioner
So, you’re after an air conditioner but are stuck on which type to purchase – a ducted reverse cycle system or a high wall split system?
Both are effective at cooling a space, but the way that they do this differs dramatically. Your choice will often depend on a number of factors such as the space that you are wanting to cool, your budget, whether your home can accommodate the system, and much more.
Ducted Air Conditioning
Ducted reverse cycle air conditioners work just as the name suggests – through a series of ducts. These are hidden within the roof space and out of sight, making it the more attractive choice. They contain a central unit, known as the fan-coil unit. Ducts then branch off of this fan-coil unit and run to different rooms/zones within your home. The air is expelled from the vents in your ceiling, which are the only visible parts of the system.
GREEN EFFICIENT LIVING CAN PROVIDE YOU WITH A NUMBER OF DUCTED REVERSE CYCLE AIR CONDITIONING OPTIONS THAT SUIT YOUR LIFESTYLE AND REDUCE ENERGY WASTAGE
There are many pros for ducted air conditioning in comparison to split systems, with one of the biggest being that you can easily and efficiently heat or cool your whole home at the touch of a button. Controlled by a thermostat, ducted systems are much better at keeping a consistent temperature throughout your whole home, but the option to have your system zoned means that you can individually control the amount of conditioned air to each room. There are two ways that you can do this; with a simple on/off switch, or a variable air volume controller which you can increase or decrease the amount of airflow to suit your requirements. The last option also allows for better air balancing throughout your system. The entire system is completely hidden within the roof cavity of your home (besides the vents in your ceilings), making it the more attractive option over split systems. Ducted systems are often a lot quieter than their counterparts, with the only noise being a quiet fan noise from the outdoor unit, and gentle passing of air through the central filtration grille.
Despite the extensive list of pros, ducted air conditioning systems also have their limitations. Ducted systems are the more expensive option to purchase and have installed. As the system is installed within your roof, technicians will need to spend a large amount of time and effort, cutting into your ceiling and this can often add to the cost. Having a ducted system installed is best done during the building or renovation of your home (but not limited to), and they can often be restricted to which homes they can be installed in. Apartments and dwellings with limited roof space often may not be able to have ducted systems installed due to this reason, and already built two-storey homes need a large amount of extra consideration and planning. They are also not the best option if you only spend an extensive amount of time in only a small area of your home.
Split System Air Conditioning
Split system air conditioners are the most ideal solution for single room heating and cooling. They are made up of two components – an indoor unit (head unit) and an outdoor unit (compressor). The indoor unit moves the cool air around the room, while the outdoor unit dissipates the heat from the cooled area (heat exchange).
Split system air conditioners are the more cost-effective choice to purchase and have installed. Due to the fact that you are not purchasing an entire system of ductwork and vents, the costs can be minimal in comparison to ducted systems. A considerably less amount of time is needed for technicians to install them, and there is minimal modification required to your home. If budget is a restraining factor, more split systems can be added to your home if you require later on, or as your budget allows. Due to the fact that split systems only heat or cool one room or space of your home, they have lower energy demands and therefore are quite cost-effective to run.
However, there are also cons involved with having a split system installed within your home. The heating or cooling capacity is limited with splits, and therefore may not be a possible option for your space. While they are the cheaper option singularly, if you need multiple units within your home, the costs can add up. The bulkiness of both the indoor unit and the outdoor unit, and the inability to hide them can often become an eyesore and stand out on your wall. So if you are looking for a neat and tidy option that is easily concealed, then a split system is not your choice.
So which option is best for me?
Each of these systems essentially performs the same job, but personal preferences and limitations can restrict which one is best for you. It is important to take into account each of the pros and cons provided so that your system benefits you for years to come.
Factors to think of when deciding include:
What maintenance/upkeep is included – A ducted system will require yearly services by a professional, while a split system will require more regular cleaning that can be completed by the homeowner, and professional servicing less frequently.
How much you want to spend – A ducted system will cost more to purchase and have installed upfront but the options to zone your system means that their running costs can be reduced. While a singular split system will cost less upfront, should you need to add more in the future, the costs can add up.
What area you are looking to cool – Do you want to cool your entire home or just one room? Should you only need one room cooled, is important to think about whether you will be wanting to cool more in the future.
Aesthetics – The way the system will look is also something to think about. While split systems stand-out on both an indoor and outdoor wall, they are becoming much more visually appealing.

Over the years we’ve become accustomed to hearing the same questions relating to having a solar photovoltaic (PV) system installed. So, as we are dedicated to education and helping our customers as much as we can, we have compiled a list of our most frequently asked questions to help you on your journey.
1. What is a grid-connected solar system?
A home without a solar system draws its energy from the electricity grid. A grid-connected solar system is a solar PV system that is connected to the electricity grid. Your household will consume the energy that is created from your solar system first, and if more is needed, it will draw the remaining electricity from the grid. It also allows your system to send power back out to the grid. If your household is not consuming the entire amount of energy that your system is creating, then that surplus is sent back out to the electricity grid. This surplus is measured and credited back onto your power bill. Depending on what state you live in and what electricity supplier you are with, this value will vary.
2. How much will my solar system cost me?
As an extremely broad question, the answer is dependent on a number of factors. The final price depends on what brand of system you choose, how many panels you have installed, whether you decide on a string inverter or microinverter and much more.
ALWAYS get multiple quotes to compare prices and remember that the most expensive quote doesn’t necessarily mean equate to the best system. In South Australia, on average a 5kW (kilowatt) system costs approximately $5,500 but there are some elements that will affect this price.
3. What size system do I need?
To answer this question, your system designer will need to understand your energy habits such as your daily usage amount, your energy usage patterns, your location, etc. From here, they will be able to offer you the correct sized system. While your installer should be able to offer you a rough estimate just by receiving your latest electricity bill, they should not be able to present you with an ACCURATE system size without first asking these questions.
4. How many solar panels will I need?
Once your installer determines the system size that your household requires, they will then look at what panels will best suit your system. Not all panels are created the same, or yield the same amount. So your installer should be working out which panels are most appropriate for your lifestyle and energy patterns. They will also need to look at elements such as your roof size and budget.
5. Will anything else affect the price of my system?
There are a few added elements that will affect the overall price of your system. Each solar PV system is tailored individually, so don’t assume that just because your family member has a 5kW system with X amount of panels on their home, means that you will pay the same price for the same system. Factors need to be taken into account such as additional labour costs for things like a double storey roof, panel mounting brackets to angle your panels correctly if your roof is flat and much more.
6. How much money will I save with my solar system?
Typically, it can take anywhere from four to six years for a system to pay itself off in South Australia. Payback times depend on a number of things such as your location, your energy consumption, daily usage patterns, how well you maintain your system, the size of your system and your feed-in tariff.
Ensuring that you have the correct sized system will speed up your payback times. Having a system that is large enough is important as it will not only cover your power consumption, but it will maximise your return on investment. But having a system that is too large will mean that you’re exporting a large surplus of energy back into the grid and as feed-in tariffs are no longer as high, you will be selling your power for less than your electricity rates. So it’s important to ensure that your system is correctly sized to maximise your return.
7. Is my roof right for solar?
Not every roof is suitable to have a solar system installed on it. Generally, there are six key factors that will determine the suitability of your system.
Orientation: While a north-facing roof is best for optimum production in South Australia, it has been proven that panels facing north.
Shade: Solar panels only produce maximum energy in full sunlight. If a part of a panel becomes
Shadows on solar panels can affect the generation values of the entire system.
shaded, then the output level is reduced. It is therefore necessary that your roof does not experience any shade if possible. Vegetation and overgrown trees can easily be removed, but shade from chimneys or poles on the roof is much more difficult to work around. If there are certain ares of you roof that do experience shading during the day, then your installer may offer you a system with microinverters to avoid your output dropping too much.
Size: Your roof has to be large enough to have the space for the number of panels that you require. The minimum sized system that can be installed in Australia is a 1.5kW, which generally equates to 6 solar panels. If your roof is not large enough for 6 solar panels, then you may need to look at other options.
Age: The age of your roof will be an indication of its structural integrity. If you are in an older home and are unsure about whether your roof will be able to safely support a solar system then it is best to have an inspection done beforehand.
Pitch: Solar panels
The pitch of your solar panels can greatly affect their power generation values.
generate maximum power when they are positioned perpendicular to the sun. Your installer will need to take the pitch of your roof into account when installing your panels at the optimal angle. If the pitch of your roof is too flat or too steep, then your installer will need to use mounting brackets to angle the panels correctly for maximum yield.
Material: While solar panels can generally be installed on any roof, there are some exceptions. Metal roofs are often the best to install a system on, while tile roofs can be quite fragile and generate an extra cost.
8. Does the temperature during the day affect production results? Does hotter weather equal greater energy production?
Many people believe that hotter weather produces more energy, however, it is much the opposite. The hotter the day, the less energy that your system will produce. This is because a solar system converts LIGHT into energy and not HEAT.
A solar panel has an optimal temperate range that is best for producing the greatest amount of energy. As the temperature rises out of this optimal range, the production efficiency begins to decrease. Excessive heat is therefore detrimental for a solar panel’s production. Instead, the days that you will find you produce the most energy are on sunny, cooler days.
9. Is there any maintenance involved in having a solar system on my roof?
Despite the rumours, solar panels are NOT self-cleaning. So, like any other appliance or installation around the home or office, we do ask that you occasionally inspect and perform a small amount of maintenance on it. You can find a copy of our maintenance manual here.
10. Do I need developmental approval to have a solar system installed?
Generally speaking, you shouldn’t need to get council or planning approval when having a solar system installed, however, there are a few instances in which you may. If you live in a council strata development, then getting approval from the body corporate may be required, or if you live in a heritage listed home then you will need to get council approval. If you are unsure whether or not you should be receiving approval, you can ask your solar installer or local council for guidance.
11. Will I still be using energy from the grid?
Yes. Your solar system only generates energy when there is sunlight, and when this energy is generated it needs to be used immediately. At night time when there is no energy being produced, your system will draw energy from the electricity grid so that you can continue to use the appliances within your home. Should you have a battery system however, it can store energy produced by your system to use when your system is not generating power.
Still unsure?
Solar systems are all individually tailored to ensure maximum power generation for your household. If you have any further questions, please do not hestitate to give us a call on (08) 8297 3422 today, to speak to one of our qualified installers.
Electricity in the home can be a marvelous tool. It can be a source of light, heat, entertainment and much more! But when it is neglected, it can become more dangerous than helpful. Have a think back to the last time that you had your home or business’s electrical system checked to make sure that everything is working safely and is compliant with the latest regulations and standards. Have you EVER had an electrical inspection carried out? Is your home old or recently built? Or maybe you are in the process of purchasing. It may be time to have an inspection done to keep you and your family safe.
According to Master Electricians Australia, 15 people on average are killed in Australia each year from electrical-related deaths inside of their homes and 300 people on average, are hospitalised. The Electrical Regulatory Authorities Council also states that between 2016 and 2017 90% of the people who were fatally electrocuted in their homes were members of the general public (i.e. non-professionals).
Many electrical issues in the home go undetected to the untrained eye. This is why it is extremely important to have your home’s electrical safety inspected to ensure that you and your family can live your days free of risk.
During an inspection, the electrician will visually inspect your home or business’s electrical system ensuring that all wiring, system, and components meet the relevant legal standards.
Some elements of the inspection will be simply a basic visual audit with recommendations regarding non-compliant components. Others will be an in-depth audit ensuring continuity of electrical system and safety switches are tested, the polarity of the outlets. Unfortunately, as most of the electrical system is inaccessible in wall cavities, a thorough visual inspection with a testing of the electrical system is the extent that can be carried out without perforating the wall.
It is important to ensure that the person that is completing the electrical inspection on your home or business is qualified to do so. By ensuring this, you will have peace of mind knowing that they are aware of and trained on the issues to be aware of and recommend how to fix the problems should they find anything.
When Should You Get An Electrical Inspection?
Despite the importance of electrical inspections, they do not need to be carried out annually. Typically, every three to five years should suffice. Technology is constantly changing and as a result, so are the electrical standards and regulations of compliance. However, there are three major situations in which you should have an electrical inspection completed immediately.
1. If you have an older home.
As mentioned, electrical standards and technology are constantly developing and changing, and therefore, the wiring that is in an older home may be severely outdated and unable to cope with the load requirement of some modern technological appliances. It also means that it may be weathered and worn and unsafe to continue using.
2. If you have experienced a major storm recently.
South Australia can experience its fair share of wild weather and sometimes, extreme weather can cause damage to the electrical elements within a home. While you may notice any damage, it is also important to seek the qualified advice of a professional to ensure that any safety features and internal elements have not been damaged. It is especially important to have an inspection completed if appliances in your home stop working after a storm.
3. Before purchasing a new property.
It is strongly recommended that you have a building inspection completed before purchasing a property. While a building inspector will examine the structural components of your home and some minor electrical components, they won’t go into much depth. They may flick switches, check that you have smoke alarms and monitor some appliances, but to ensure your home’s electrical integrity, having an in-depth inspection completed is strongly recommended.
Your electrician will be able to identify in more depth, any significant electrical issues that your home may experience and take a closer look at the wiring that is installed. You can never be too sure of what work the previous owner may have had done in your home, or if they even used a qualified and licensed professional. Having an inspection done will ensure that you do not get presented with a hefty bill or an unsafe home after purchase.
Why Should You Get An Electrical Inspection?
1. To identify any faulty wiring.
Faulty wiring is a common cause of fires and injuries by electrocution. As mentioned, every year in Australia, there are roughly 300 people admitted to hospital as a result of electrical malfunctions within their homes. Electrical wiring has a certain lifespan, so just because it may have been safe ten years ago, doesn’t mean that its age hasn’t impacted its safety today. Many old homes have never had their wiring upgraded and wiring safety and efficiency have come a long way in a short span of time. Power and lighting circuits are now required to all be on individual safety switches. This came into effect in 1991, so if your home was built before that, then chances are your electrical system is non-compliant and not protected.
2. To notice any issues with your smoke alarms.
A smoke alarm can help save lives by providing you and your family with a strong warning if there is a fire in your home. Legislative requirements state that it is compulsory that ALL South Australian homes be fitted with a working smoke alarm and there are a few rules and regulations as to where the smoke alarm should be located and whether there should be more than one. Smoke alarms are now required to be hardwired, with a battery for back up.
Many injuries and fatalities from fires in Australian homes would have easily been prevented if a smoke alarm was present, or if their smoke alarm was working. Over time, some smoke alarms have become outdated and no longer comply with Australian standards.
During an electrical inspection, the electrician will note your smoke alarms location/s, whether you have enough in your home and whether they are working and compliant.
3. Identifying overloaded circuits.
Electrical circuits are designed to have a limited amount of electrical current. An overloaded circuit occurs when there is more demand on the circuit than it can safely handle.
If your home has limited outlets, you can be tempted to utilise multiple powerboards which would increase the demand on the circuit. When the limit is exceeded, the circuit breaker should trip, shutting off the power and removing the threat to your safety. If the circuit breaker was to fail, an overload on the circuit would cause the wiring to overheat and the wire insulation to melt, which may result in a fire.
Electrical installations can age and can become overloaded very easily, particularly in old homes where the wiring was not designed for the number of electrical appliances in use today.
The most obvious sign of an overloaded circuit is the circuit breaker tripping and shutting off the power. However, some other signs to look out for are:
Buzzing outlets or switches
Outlets or switches that are warm to the touch
Burning smells
Power tools or appliances that seem to lack power
During an electrical inspection, the electrician will identify the electrical demands of your circuits and provide you with any corrections that are necessary to avoid serious threats to your safety. These corrections may be the installation of new and additional circuits or reducing the load on each existing circuit.
4. Ensuring that your home’s electrical system is up to code and is compliant
There are certain electrical standards that your home’s electrical installation and wiring must comply with. It is impossible to know what type of work has been done on your home previously, and whether the previous owner used a licensed or unlicensed technician.
Understanding the current state of your electrical system is extremely important to be aware of your level of safety within your home and how much money you may need to pay to fix the legal issues.
In Austalia, it is illegal to complete your own electrical work if you are not a qualified tradesman. Licensed tradespeople have the equipment, training, certification, and knowledge to do the necessary work safely and in accordance with appropriate regulations and rules.
Conclusion
For the safety of you and your family in your home, it is clear to see why spending a little bit of money in the short term on an electrical inspection, may save you much more in the future, including your lives. Have a qualified electrician inspect your home or business’s electrical system to ensure that it is compliant and running as it should be.
Why Should You Have Your Air Conditioner Serviced?
Having your air conditioner serviced before the hot weather hits is smart for two reasons. Not only does it mean that you will be prepared for when the temperature starts to rise, but it also means that you will beat the rush of people trying to get theirs serviced during summer.
What Is Done During A Service?
During a scheduled routine service, a Green Efficient Living technician will complete a number of checks on the outdoor unit and indoor unit to ensure its compliance and that it is operating as it should.
The first thing that our technicians do will ask you whether or not your system is functioning properly. Have you heard any noises lately? Has it been playing up or not running as it normally would? Etc.
The return air will be then taken out and checked over, during which time our technicians run your system to inspect the outdoor unit. They will get the pressure readings, check electrical voltages and currents and ensure that there is no debris on the rear coilers of the unit.
After the service of the outdoor unit, they will then get into your roof to inspect that all electrical terminals are still tight, that the ductwork does not have any imperfections such as rips and that the main condensate drain isn’t blocked. During this time they will also inspect all zones by turning them on and off to ensure that they are all opening and closing as they should.
Our technicians attended a service call for a faulty air conditioner and upon further inspection, the issue was simply dirty filters.
Can You Service Your Own Air Conditioner?
There are basic maintenance jobs that you can do yourself as the homeowner, such as cleaning the filters and ensuring that the outdoor unit stays unrestricted (see our post on that here). But when it comes to a complete annual service of your unit before using it again, this MUST be left entirely to the professionals. The smallest of attempts at servicing your own air conditioner can lead to serious unit damage or even electrocution!
Why Should You Have Your Air Conditioner Serviced?
The easiest way to understand exactly why you need to regularly service your air conditioner is for the same reason that you regularly service your car. You do not drive your car unserviced until it breaks down beyond repair and you are forced to buy a new one. Instead, you service it regularly to AVOID any serious breakdowns – an air conditioner is much the same.
There are many reasons why having your air conditioner professionally serviced is important:
1. It improves energy efficiency and saves you money on your electricity bills
Without periodic maintenance, your air conditioner will find it hard to run in prime condition. When this happens, it has to work a lot harder and consume more energy which in turn costs you more on your electricity bills! Avoid paying more by having a professional complete a service on your air conditioner to ensure that it is running as efficiently as possible.
2. It improves air quality
When your air conditioner isn’t working efficiently, it cannot properly filter the air is distributed into your home. An air conditioner that is running in perfect conditioner successfully filters out pollutants, pollen, dust and allergens, meaning the air that you and your family are breathing is cleaner and safer.
3. It extends your unit’s lifespan
Regular servicing and maintenance will extend the lifespan of your unit for all of the reasons mentioned above. It faults are left undetected, they can cause serious issues for your system in the future. These issues may result in costly repairs or even a unit replacement! However, by servicing it regularly you are increasing your system’s lifespan and keeping it running in perfect working order for many more years to come.
The professionals at Green Efficient Living recommend having your unit serviced annually, even if it is not showing any signs of faults or issues. To book your annual service, call us today on (08) 8297 3422.
Note: Green Efficient Living is currently holding their annual Pre-Summer Service Sale! Take advantage of our discounted prices and have your unit serviced before the hot weather is here!
We’ve heard it all before: ‘change your globes to LED globes!’ But why? Are LED globes really as good as they say? Is there really any point spending time and money switching your existing globes to LED ones? Why are LED globes so good?
LED stands for Light Emitting Diode and is an increasingly popular alternative to your standard halogen, incandescent, or CFL (Compact Fluorescent Lamp) globes. If you haven’t already substituted your current globes for LED ones in your home or business, then your lighting would already contain one of the other three options mentioned.
What Are Your Lighting Options?
Firstly, let’s look closely at the other traditional options. Not too long ago, you had the choice of incandescent globes, halogen globes, CFLs and LEDs however, it has been predicted that halogen lights will disappear from Australia within the next two years as the country shifts towards more efficient and environmentally options. Australia began the phasing out of poor-performing incandescents in 2007, requiring homeowners and businesses to instead install energy efficient lighting to cut greenhouse gas emissions. Then in 2010, the Australian Government then enacted a ‘Minimum Energy Performance Standard’ law ensuring only the highest performing products are to be available. However, these standards relating to incandescents, halogens and CFLs still do not meet the same energy efficiency as LEDs.
CFLs
Your CFL bulbs are reasonably cheap to buy but can cost you more to run over time. They can also wear out faster if put in a light fitting that is switched on and off constantly, such as your bathroom or kitchen. They can’t be used outside very often as they don’t work well in extreme heat or cold and can take a little longer to reach maximum brightness. They do, however, have a slightly longer lifespan than incandescents and halogens, and are slightly more energy efficient.
They work via a chemical reaction known as fluorescence. The tube contains mercury that becomes ‘excited’ as electricity is passed through the system. When the mercury begins to settle, it gives off light.

Incandescent Globes
Incandescent globes were simple and cheap to manufacture and therefore purchase, but besides that and their bright light, the pros stopped there! Their lifespan is extremely short and they lose around 90% of their energy to heat. However, despite this, they were probably the most common light bulb that you had in your home currently until the government placed a heavy regulation on the sale of incandescents operating at a certain energy efficiency.
Incandescent globes have the classic ‘light globe’ shape. They contain a mental filament made of tungsten inside, that acts as a bridge for electricity to flow over. As the electricity surges, the filament heats up and it begins to glow giving off light. This is also the reason why the globe gives off so much of its energy as heat, and why it is often hot to touch straight after it has been turned off.

Halogen Globes
Halogen globes are a type of incandescent light, however, are stronger, designed to withstand higher pressures than incandescents and are around 30% more efficient. But while they are labelled as ‘low voltage’, they still use approximately 35W to 50W per globe, so they are still not an efficient choice to have within the home. They can also become quite hot and can, in some circumstances, becomes quite hazardous.

LEDs
LEDs are often the more expensive option to purchase per globe compared to their more traditional counterparts, however, they are longer lasting and much cheaper to run! Using around 75% less energy than CFL globes and lasting two to three times as long, when we look at LED globes in comparison to the other options, it is clear to see just they’re the obvious choice!

What Are The Benefits Of LEDs?
Energy Efficient
The first and most beneficial reason is that they are extremely energy efficient and will save you money on your electricity bills. They use less power (watts) per unit of light (lumens) and can, therefore, provide up to around 100 to 200 lumens per watt. In contrast, CFL globes use around ten times the amount of Watts as LED globes. Incandescent globes also lose a lot of their energy to heat rather than light (90-95% to be exact), so they are extremely inefficient to run. For reference, a 60W (watt) incandescent bulb will only put out as much light as an 8W LED bulb! It doesn’t really make sense to put these globes in your space, when 95% of what you are paying for, you are not able to utilise. So while they might seem the perfect option upfront due to their low cost, they are considered a much more inefficient option than LEDs. In a typical Australian household, lighting makes up for about 7-10% of your electricity bill (sa.gov.au). So when you think about how much you rely on lighting in your home to live comfortably, ensuring that you have the most energy efficient lighting is a small change that you can make to save big on your bills.
Above you can see a comparison of the average energy usage in Watts per Lumens of typical globes. You can see that the brighter the globe (lumens) the more energy it consumes (watts), as you would expect. However, LEDs remain the lowest option!
Longer Lifespan
Another positive is that they have a much longer lifespan than other traditional globes. To put it into perspective, an average lifespan of an LED globe is between 15,000 to 50,000 hours, while halogen globes last a mere 1,000 to 5,000 hours. So the need to consistently purchase and change your globes lessens when you purchase LED globes. That means less money spent on always buying new globes!
A 10W LED bulb would cost $39 in total to buy and run over 10 years. Over the same about of time, five 42W halogen globes would be needed at a cost of $148. or two 12W CFL bulbs at a cost of $48.
Environmentally Friendly and Recyclable
LED lights are non-toxic, better for the environment and your family and currently the greenest choice on the market today! CFL globes, along with fluorescent tubes, contain a small amount of mercury, a requirement of 5 milligrams according to Australian Standard (environment.gov.au). While this amount of the toxic mercury does means that handling CFL bulbs requires more care and precautions, the short-term nature of the potential exposure when broken does not create a potentially large risk. Gloves should be worn to clean up a broken or no longer working CFL bulb and the remnants should be placed in a plastic bag and given to a nearby waste or disposal centre to avoid the mercury from entering the environment. To find a centre near you, head to www.recyclingnearyou.com.au. Incandescents and halogen globes cannot be recycled due to the fact that they contain a Tungsten filament that cannot be reused, but they may be able to be taken to the same recycling centres as CFLs. The best way to dispose of these globes is to simply wrap them in a few layers of paper and throw them in the garbage, not the most environmentally friendly option, or call your local disposal centre to see if they will take them. LED globes, however, do not contain any hazardous materials, are not made of glass and are completely recyclable. So if they break or stop working, simply wrap them in paper and place in your recycling bin! Safe on your family and the environment!
More Flexible Lighting Options
LEDs are considered to be ‘directional’ light sources, meaning that they can be designed to emit light in a specific direction. Those with LEDs installed in their homes can look forward to focused and concentrated light because of this, and a more energy efficient result. Incandescent and CFL globes emit light in all directions, meaning that they are often radiating heat and light in directions where it is not needed, wasting energy and your money. Having the ability to focus your lighting in your desired direction, means that your lights do not have to work as hard to illuminate the space, and therefore your energy bills stay lower.
LEDs can withstand frequent switching on and off making them perfect for outdoor flashing light displays, sensor lighting, or in areas such as the kitchen, or bedroom where lighting is commonly turned on and off. As well as this, LEDs are able to to be successfully dimmed. Most traditional lights can only be dimmed to 30% of their light output before they stop working, but LEDs are able to operate at a mere 10% of their light output (when used with LED suitable componentry).

Durability and Safety
As previously mentioned, LEDs are much more durable and able to withstand harsh weather conditions due to their ability to operate under extreme temperatures and low voltages. This enables you to place them anywhere around your home, indoors or outdoors, as the cold, wind, rain and extreme heat will not affect them. LEDs also do not contain any filaments or glass enclosures but are instead mounted on a circuit board with soldered leads. This makes them virtually unbreakable and able to withstand shocks, vibrations and external impacts. Safety is no concern with LEDs as they do not give off heat and contain no harmful chemicals.
LED Lighting can be used outside due to its durability.
While different globes work for different situations, it’s obvious to see why LED globes are the clear choice to have within your home or business. With halogens and incandescents slowly being phased out, the only competition that still stands are the traditional CFL globes. Despite CFLs still being a good choice, the benefits of LEDs in comparison far surpass those of CFLs.

We spend many hours in the home or office, surrounded by unnatural lighting that causes issues many people are unaware of. Glare is one of these issues that seems to be considered more of an annoyance than a health issue. But glare can cause many serious issues if not dealt with correctly. In this blog, we discuss just what glare is, how it can affect your health more than you think, and how to eliminate it.
What Is Glare?
Glare is defined by the International Commission on Illumination (CIE) as ‘visual conditions in which there is excessive contrast or inappropriate distribution of light sources that disturbs the observer of limits the ability to distinguish details and objects’. The Illuminating Engineering Society (IES) describes it more simply as too much light and ‘an excessive contrast in which the range of luminance in the field of view is too great’. Whatever the definition is, while you may think that a small amount of glare is simply just annoying, it may be doing more damage to your health than you think.

Why Is Glare Bad?
Glare can cause many health issues, ranging from being a minor annoyance that causes some discomfort and squinting, to serious eye strain, impaired vision, decreased safety, visual and bodily discomfort, injury to your eyes and a decrease in your overall health. It is also one of the leading causes of eye strain, less-than-optimal vision, and serious eye damage.
Think about how many times you have sat there and seen a flicker of light reflecting off of the table in a room. You squint your eyes to reduce its effect, or your turn your body away so that you cannot see it. While this may seem annoying, the squinting and straining of your eyes can cause serious headaches and vision impairment, and the position of your body may cause muscle strain and discomfort.
This minor annoyance has now presented itself with serious outcomes if left untreated.
Why Does Glare Occur?
Glare occurs where a ‘source of unshielded light is brighter than the average field’ or when there is a stark contrast between a bright light and the average light of an area. To explain this further, a street lamp may not cause glare at dusk, but that same lamp may cause glare in pitch black darkness. This is because the contrast between the light from the lamp and the surrounding area is greater at night than it is at dusk.
The most common reasons why glare occurs around the home or office are computer screens, sunlight, and incorrectly shielded light and poor lighting design. The proper precautions must, therefore, be taken in order to eliminate glare and provide a healthy and productive environment. Good lighting design must be considered to diffuse the light in the room evenly to reduce the luminance or contrast. The luminance must be balanced and uniform within a room to reduce or eliminate glare and make your working or living space entirely comfortable.

How Can Glare Be Eliminated?
Thankfully, there are many ways to control glare so that your days can continue with little annoyance and ensuring that the light is uniform throughout the room is the best way of making this happen. To do this:
Install blinds that allow light to filter through softly, but remove the harshness of direct sunlight.
Install dimmers that allow you to adjust your lighting accordingly. This makes it easier to control your lighting as the daylight changes throughout the day.
Make sure that your lighting is indirectly situated. It may help to have a professional from GEL assist you with this. Having light directed upwards so that it can bounce off the ceilings and walls rather than direct light that is situated downwards is important in dispersing light evenly.
Try to position your computer screen away from a window and so there is no light reflecting off of the screen. Computers emit a lot of glare so it can help to have a soft light source from behind. Sit a lamp with an LED light, behind your screen to soften the contrast and reduce the glare.
Move shiny surfaces, such as glossy tables, away from direct sunlight that can cause harsh reflections. Choosing surfaces with a matte finish will also assist in reducing the glare even further.
Keep your wall colours soft so that when the light hits them, there is very little contrast and reflection.
