Energy Efficient Louvre Windows

With good design, it is possible to take advantage of natural, fresh breezes to cool your home or office and use sunlight to light dark rooms. This reduces the reliance on power hungry air conditioning systems and electric lighting, both of which contribute to greenhouse gas emissions via their use of electricity.

Natural Ventilation

Why close up your home and run a power hungry air conditioner when you could open it up to take advantage of fresh, cooling breezes to cool you down the way nature intended. To create cross flow ventilation, openings are needed on opposite sides of a room to allow fresh air to enter, flow through the room and then exit.

Ventilation openings are often needed in internal walls as well as external walls.

Another good way to naturally cool a room is to place some windows up high. This is effective because rising hot air is able to escape the room through the high up windows, helping to keep the room cool.

Twice as Open

When it comes to cross flow ventilation, the larger the openings to allow ventilation, the greater the cooling effect is. This is where Altair Louvre Windows are ideal as they are twice as open as regular windows, and therefore offer twice as much fresh, cooling ventilation as regular windows.

Keep the Draughts Out

Of course, in the winter, the last thing that you want is windows that let in cold draughts. Breezway Altair™ Louvre Windows not only open up to let fresh air in, they also shut tight to keep cold draughts out.

Energy Ratings

Most new homes and buildings require energy ratings. These energy ratings can be produced using House Energy Rating Software packages (like BASIX or BERS) or by adhering to 'checklists' laid out in the Building Code of Australia. Extensive modelling has shown that buildings including Altair™ Louvre Windows can easily achieve excellent star ratings and are able to comply with energy efficiency requirements.

Details on the rated energy performance of Breezway Altair™ Louvre Windows can be found on the Window Energy Rating Scheme (WERS) website www.wers.net
