Australia is a beautiful country open with abundant sunlight and good weather. Harvesting natural e principle behind Australia opening roof system is quite simple. There are two screens; the lowesunlight and rainfall not only conserves the natural resources but is effective in reducing the costs of ventilation and artificial lighting. Australian opening roof systems are a good innovative design that is rapidly being incorporated by Greenhouse owners. Using Australian opening roof system has become a prime concern of greenhouse growers with stress being put on good ventilation as a paramount under Australian conditions.

As hot air moves up, roof is the main site for ventilation. Previously vents had been in use but a new roofing system by Living shade company that is marketing the Ludvig Syenson (LS) screen range has brought a revolution in ventilation systems. Thr screen is a thermal screen that functions to provide warm green house conditions while the upper screen provides shade.

Using these sliding roof screens either together or alternating them can provide a wide range of climatic conditions. The screens operate on independent levels with separate motors, computer control and thermostat. Lower screen has been manufactured as waterproof plastic thermal screen and the other screen is a solar shade screen.

ns operate on independent levels with separate motors, computer control and thermostat. Lower screen has been manufactured as waterproof plastic thermal screen and the other screen is a solar shade screen.

The opening and closing of these screens are preset according to the temperature by the thermostat controls, wired back to the control units. Greenhouses maintain temperatures ranging from 20 to 25 degree Celsius. During the morning hours the temperature is 20 to 22 degree C so the lower or thermal screen and the upper or shade screen are open. This lets in maximum sunlight and air needed for the plants, making perfect growing conditions.

While during the day after the temperature reaches 25 degree C the top screen close but the lets the light in, while heat is reflected back by the aluminum on the screen. At night both screens are closed due to varying temperature. The flexibility which is available with Australian opening roof system and computerized environmental control that operates independently of human control.

Innovative ideas have increased production while reducing the cost of production. Harvesting natural sunlight and ventilation through Australia opening roof system has changed the greenhouse industry with computerized roof system with dual mode of being manually operated also.
