Nature's own cooling system is shade and a breeze.  Your home provides the shade, Breeze Power Natural Cooling provides the breeze to prevent the build of of heat in rooms and the roof space.

Modern houses are designed on the assumption that they will be air conditioned to make them liveable in summer.  With dark tiled roofs, large windows and no ventilation, they heat up like ovens, even in moderate temperatures.  

Relying only on air conditioning to cool your home is as logical as running a 'fridge inside an oven.   

Why not have the best of all worlds - an air flow cooled, breeze filled house for average summer days with a modest air conditioner in a living area used only on  heatwave days.

Heavy advertising has lead us to believe that air conditioning is the only way to cool our home.  But with  Breeze Power Natural Cooling as your primary cooling system, you can reduce the system size and running times of air conditioning or do without it altogether. 

There is no need  for any other form of roof space ventilator. However, If you already have "Whirly Birds" in your roof, they can be incorporated as part of the exhaust system for a Breeze Power Fan. 

The combination of Breeze Power Natural Cooling and some form of radiant heating either in the floor, ceiling or  low wattage panels provides a more 
natural, energy efficient year round alternative to the heating and cooling provided by reverse cycle air conditioning.

Look at the unique benefits of Breeze Power Natural Cooling.

• Instantly fills your rooms with naturally cooling, fresh air breezes that move over your skin to cool and refresh naturally, just like fanning your face on a warm day.  You feel much cooler surrounded by moving air than still air because moving air evaporates moisture from the skin.
  
• Indoor air is fresh and healthy.  The fan generates 30 to 45  air changes per hour through rooms to carry away stale air, cooking odours, insect spray fumes, out-gassings  from synthetic furnishing and building materials, mould spores, dust mites and water vapour.
  
• Makes a dramatic difference to roof space temperatures.  the in roof Fan changes air in the roof space between 50 and 70 times per hour, too fast for heat to build up much beyond the outside temperature. You would need 30 or more whirly type wind turbines and a strong breeze to achieve this rate of airflow.
  
• Uses only 250W of power at a running cost of under 11 cents per hour.  Costs far less to run than even a one room air conditioner yet cools and ventilates the entire house.
  
• Enhances the performance of ceiling insulation which otherwise will hold unwanted summer heat in rooms as efficiently as winter warmth.
  
• The combination of Breeze Power and radiant heating provides a year round, low cost, maintenance free alternative to reverse cycle air conditioning. You can downsize dramatically or even eliminate the need for air conditioning and save hundreds of dollars in purchasing, operating and maintenance costs.
  
• Breeze Power cooling is invisible, quiet and virtually maintenance free.  

What does a Breeze Power System consist of? 

• A large, quiet  Whole House Fan installed invisibly inside the roof space.
• A single automatic ceiling shutter on the ceiling below - wind operated or motorized.
• A variable speed control switch (optional timer available)
• Exhaust vents installed on the roof or, preferably, under the eaves.

How does it create the air flow?.

When you switch the system on, the in-roof fan begins to rotate and the blades of the ceiling shutter automatically open.

The Fan creates a powerful suction effect immediately sets indoor air in motion as it is drawn from rooms,, travels  though the house towards the fan location (usually a hallway or the landing at the top of the stairs).  The air rushes up through the ceiling shutter and fan blades into the roof space.  Fresh air flows in through partially opened windows.  Curtains wave gently and you feel a subtle air flow on your skin. 

Air in the roof space is continuously displaced by the rush of incoming air and pushed outside so fast it cannot build up to the furnace-like temperatures that heat up your home.  Extra vents under the eaves or, if there are no eaves, roof mounted vents allow the fan to push the hot air out.  Roof space air is changed around 50 to 70 times per hour.

Existing "whirly birds" can be incorporated as part of the exhaust system but have to be supplemented with additional vents as their free air area is far too small.   

The table below sets out the minimum areas of free air required in the roof space to cope with the air flow generated by the Fan.

I have no roof space - can I use a Breeze Power System?

In homes with flat roofs or all raked ceilings, Breeze Power fans are installed very successfully in roof mounted canopies with louvred sides. VIEW PICTURES

The canopy is customized to suit each project in terms of size, colour and the angle and profile of the flashing if the roof is sloping.  The fan is still located over a transit area of the home with an automatic ceiling shutter trimming the ceiling opening below.

In cooler climates the ceiling shutter should be motorized rather than wind operated to provide positive closing to protect against draughts in Winter. 

Which system size is best for my home?

In mostly temperate regions in New South Wales, Victoria and South Australia,  we want to achieve a minimum of 30 to a maximum of 45 air changes per hour through a home.  In the hotter temperatures of  W.A, Queensland and the Northern Territory 40 to 50 air changes per hour.  The cooler climates of Tasmania and New Zealand need only around 30 air changes per hour.

To calculate which Breeze Power Natural Cooling system will suit your home, work out the cubic area, that is the overall length x width x ceiling height of the house, excluding the garage.   In a two storey or split level home, work out each level and add them together.

Multiply the cubic metre area of your home by the number of air changes you need for your region.

Look at the M³/H rating for each fan on the table above and select the one nearest to your sum.  

Example:  Home in New South Wales L18M x W 12M x H2.4 = 518.40 cubic Metres.
multiplied by 35 air changes = 18,144 cubic metres per hour is required.  The 915mm fan produces 17,500 cubic metres per hour.  On high speed the fan would provide  33.75 air changes per hour (17,500 ÷ 518.40Mª = 33.75) . 

If your calculation puts you in the middle of   two sizes, see if the larger Fan and shutter will fit.

Once you know your fan and shutter size, you can then see if it will fit in your home. (see the Technical Specification on the brochure you can download).
