Why Switch Off Standby Power?

Power used by appliances can account for 25% of the total energy consumed in an average household. As the majority of these energy-sucking devices use a built-in standby mode even when they are not operating, power is consumed day and night. Switching off these ‘vampires’ at the power-socket eliminates standby power – saving the average household at least $120 per year on their electricity bills.

On average, household standby power consumption remains at around 10% of total residential energy consumption. Nationwide, gadgets in standby power mode cost Australian consumers an extra $1.1 billion per annum in energy costs and result in nearly 5.7 million tonnes of carbon dioxide emissions.

The number of appliances that run on mains power in a typical house has increased to 67 (ranging from a low of 26 to as many as 175 appliances in some homes). The home office and home entertainment categories now equate to over two thirds of standby power consumption, with both big vampire gadgets like computers and smaller vampires like phone chargers. NB: phone chargers are a particularly sneaky species of vampire as they consume standby power even when the phone is unattached!

The worst offenders (in terms of power consumption in standby and off modes) are:

  •   Computers and related equipment;
  •   LCD and plasma televisions;
  •   Set top boxes;
  •   DVD recorders;
  •   Games consoles;
  •   iPod docking stations;
  •   Integrated and portable stereos.

However any appliance that requires a remote control or has a digital clock display will suck energy, even when not in use. Some less well known vampires include: counter-top appliances such as microwaves, coffee machines, bread makers and mixers. Less obtrusive vampires include camera battery chargers, electric toothbrushes and cordless power tools. And even many energy star-rated appliances keep their clock settings when turned off.

Have you had enough of the vampires invading your home and wallet? Forget about a wooden stake through the heart, to kill a vampire you simply need to eliminate its source of power by switching off at the wall. If you find it hard to reach power sockets stuck behind furniture (or simply find it difficult to remember), consider using an EcoSwitch to wage the war. With a single flick of the green glowing switch, those energy-sucking vampires will soon become nothing more than folklore!

The future of concrete slabs is here.

cupolex logo

Reozone is now supplying the Cupolex Structural Dome system in Sydney and surrounding areas. This system has many benefits such as environmental advantages being a recycled product , OH & S benefits being a light and easy to install and no waste to name a few.

Cupolex is not only a standalone Green product with excellent thermal ratings but in conjunction with a fan forced ceiling cavity air movement system, energy costs can be reduced significantly. Computer models are showing up to 50% reduction in energy usage. Reozone and their partners are continuing to optimise the system in a range of climates to establish its energy saving potential in the context of the BCA (star-rating) and BASIX (% reduction) compliance requirements.

cupolexWith each slab that is poured, the delivery process can be minimised by having the Cupolex product and mesh delivered on the one truck thus being more efficient and lowering carbon emissions at the same time. The Cupolex domes are interlocked and stacked neatly on pallets where other systems require a mesh delivery, a truck and trailer for delivery of pods and another truck to pick up waste. Reozone delivery trucks can transport up to five house slabs at any one time.

The average building lot is becoming smaller so site congestion is a major issue for developers and builders. The Cupolex system, on average, takes up two pallet spaces per unit/lot.

Concreters estimate they save at least 8 man hours per slab with not having to bar chair the domes and clean up mess as you do with other systems.  Our customers no longer need to be worried about penalties from councils for waste being blown off site.

More builders are now using the Cupolex system because of the benefits mentioned above. Reozone has identified Cupolex as the concrete void system of the future.

Reduce your energy bills with the right awnings

sun control

sun control

Outdoor shading is an essential part of a home’s energy saving strategy and awnings have long been considered a great solution. The role of an awning is to provide the flexibility to regulate the amount of solar energy that reaches the facade, especially glass, of your home. Awnings reduce the ability for solar energy to be converted to radiant heat in your home benefitting your living space with comfortable levels of visual light and more flexibility to naturally ventilate your home.

In Winter, an awning is best utilised to reduce visual light transmission when required and is retracted when you want the solar energy to heat your house.

In Summer, the awning shields your façade from solar energy reducing visual light combined with massively reducing solar load, which converts to radiant heat on contact with any exposed surface. The passive control of solar energy with external awnings saves you money and saves the environment. Reduced reliance on mechanical equipment costs such as air conditioning and heating ultimately reduces your energy bills and is less demanding of utility infrastructure and natural resources.

THE FACTS

  • Direct radiation from the sun is the most important component shading has to address. Reflected light is strongly influenced by the reflecting surface. For example grass will reflect 20 – 30% and snow more than 70%. Single pane glass reflects only less than 5%.
  • External shading devices are the most effective in reducing heat gains because they intercept and dissipate most of the heat in solar radiation before it reaches the building’s surface. This differs to internal shading where the sun’s rays hit the building or window and then traps the heat in. This heat is hard to remove.
  • With a markilux awning it’s possible to achieve a 95% reduction in solar thermal energy radiation, however the average awning should block out about 80% of the heat load.
  • Recent statistics by the NSW Government estimate that the average Australian home spends $265 a year on airconditioning. By installing adequate outdoor shading and appropriate awnings you can eliminate the use of air conditioning all together or reduce it by up to 75%
  • It is estimated that adequate external window coverings can reduce carbon pollution by 200 kgs each year.

TIPS WHEN CHOOSING AN ENERGY SAVING AWNING
The type of awning that you choose to install is also crucial to the savings and energy saving outcome. The traditional image of an awning (ie: a scalloped piece of cloth and bit of metal!) has been replaced by modern outdoor shading solutions. The modern markilux awning incorporates energy saving ability but also design, image and aesthetics, adapting themselves ideally to their surroundings and giving sun protection of
the highest quality.

  • TYPE: When it comes to energy savings, there is no real difference in retractable or fixed awnings during peak Summer months, as they are both effective at blocking sunlight and reducing energy usage. During the Winter however, some homeowners may prefer retractable or adjustable awnings because they can be retracted or adjusted to expose more of the window glass and thus let more light and heat in.
  • SIZE: Proper sizing is important to optimise for blocking the summer sun and allowing the winter sun to shine through for passive solar heating.
  • POSITION: The orientation of the window to the sun as well as your latitude, affect how far away the awning must project from the house wall. In Australia, awnings should be fitted to north, east and west facing windows and are more effective for blocking out morning and afternoon rays than internal blinds, curtains or shutters. Window awnings can reduce solar heat gain in the summer by approximately 65% on south-facing windows and 77% on west and north-facing windows.
  • CIRCULATION: Awnings require ventilation to keep hot air from becoming trapped around the window. Grommets (eyelets) or other openings along the tops and sides of an awning can provide ventilation. The awning may also open to the sides or top to vent hot air. An awning can greatly assist in the ability to naturally ventilate your living space improving air quality.
  • MATERIAL: Choose fabrics that have a minimum 98%UV and 50+SPF factor. Lighter coloured fabrics will be cooler and lighter underneath and darker coloured fabrics absorb the heat more, so can be warmer and darker under the awning. Quality is key. The fabric should be water resistant, durable, tear proof and not susceptible to rot, quick drying, resistant to heat, cold and other environmental influences.

Tips for getting the most out of your air conditioning system

  1. Be sure to choose a professional who is suitably accredited and qualified to install air conditioning systems. Improper installation can result in leaky ducts and poor air flow as well as diminished performance levels.
  2. Properly maintaining and cleaning the air filters in the air conditioning system can save money and extend the life of the unit. Fujitsu offers a vast range of split systems to choose from and the front panel can be easily removed for cleaning.
  3. Be mindful of the space you are air conditioning. Are the doors and windows closed when the system is in use and is the ceiling insulated? All these factors can affect heat retention in the room and how efficiently your system will operate.
  4. Using timer settings on air conditioning systems helps manage energy consumption as well as home comfort. By setting the unit to turn on before the household wakes for the day, or gets home from school or work, gives the home time to warm up and means less demand is placed on the system when the home is occupied.

The Environmental and Cost Benefits of Solar Hybrid Air-Conditioners

Solar power is gradually becoming an energy source that supplements traditional energy supplies and results in energy efficiency, cheaper power bills and a reduction in carbon emissions.

A new air-conditioning system has recently become available in Australia that combines solar power and traditional energy – the Sealey Solar Hybrid Air-Conditioner.

Easy Efficiency is the first distributor of this sustainable air-conditioning system in NSW. Nathan Barton, Director of Easy Efficiency, said he chose to distribute this air-conditioner for a number of reasons:

“This hybrid unit uses half the power of a standard electric air-conditioning system, and as a result emits half the amount of carbon into the atmosphere,” Nathan Barton, said.

The cost of running the unit is also half that of a standard air-conditioning system, and it actually pays for itself in energy savings.

“The Sealey Solar Hybrid Air-conditioner can be used in homes and small to medium businesses and heats and cools. Units have already been nstalled across Australia  – from the cooler temperatures of Tasmania to the hot humid temperatures of Far North Queensland.

This new solar hybrid unit has also been quality tested in a number of areas. It has undergone rigorous testing by a division of the SGS Australian laboratories and meets and exceeds all Australian standards. They have achieved the quality management rating:  ISO9001 and achieved seven years of the highest ratings.

Designed for commercial and household use, they are built to last and come with a 5-year warranty.

“Their durability is great for the consumer, “ said Nathan Barton, “and it’s also good from a sustainability point of view, as the Sealey unit has a long life expectation.”

Its durability has been achieved by using state-of-the-art technology and quality parts. They include Toshiba compressors, and use inverter technology. This results in power savings, has a longer lifetime, and makes them whisper quiet and ozone friendly.
