    The Australian / New Zealand Standard, 4740 (2000) Natural Ventilators- Classification and Performance, is discussed in this paper. It has provided an ideal platform to standardise and make accurate comparative analysis of natural ventilators exhaust flow rates. Experiments with various manufacturers` ventilators were undertaken, comparing them to, the relative performance of an unimpeded 300mm diameter opening; the methodology employed and the results of this testing are disclosed in this paper. New advanced ventilation designs and test procedures are also described in this paper, such as the long volume turbines and improved wind directional vanes, with increased exhaust flow rates. Product innovation and improved performance and test results utilising the test facility developed for the Australian / NZ ventilation standard has led to the commercialisation of new products such as the Wind Directional Skylight Ventilator and the roof siphon that utilises the hot air in the roof space to further drive the natural ventilation process. The paper concludes with discussion on the detailed product design of the unique Wind Directional Skylight Ventilator, its measured exhaust flow rates, ability to reduce condensation and improve indoor environmental air quality via natural ventilation and daylight
