The Commissioners of Irish Lights are currently considering the WINDWORKER in the lighthouse of Inishtrahull Island. For further information of lighthouses of Ireland see www.cil.ie
Mr Glenn Murcutt - Internationally Awarded Australian Architect
In 1992 Mr Murcutt was awarded the prestigious Alvar Alto Medal for Architecture in Helsinki. Previous winners were Mr Joern Utzon of Denmark (designer of the Sydney Opera House), Mr Hakon Ahlberg of Sweden, Mr James Stirling of Great Britain, Mr Tadao Ando of Japan and Mr Alvaro Siza of Portugal.
Mr Glenn Murcutt used THE WINDWORKER on a building denoted as the Marika-Alderton house for the Yirrkala people in Arnhem Land in Australia's Northern Territory. This building won a Royal Australian Institute of Architects award at both State and National levels. see "Murcutt" at www.awards.raia.com.au/cgi-bin/search.pl
In association with Troppo Architects, he designed the Bowali Information and Visitors Bureau in Kakadu National Park also in the Northern Territory. This structure also won two RAIA awards, one at State level and the other being the Sir Zelman Cowan Best Public Building Award at National level.
Through Mr Murcutt's architectural influence, WINDWORKERS have been used within Australia and overseas the most notable being for Dutch architects in the Mission of the Benedictine Monks in Dar-es Salaam in Tanzania, West Africa.
In April 2002, Mr Murcutt was awarded the world's top architecture achievement - the Pritzker Architecture Prize. see www.pritzkerprize.com/laureates/2002/index.html

Comparison tests of other (turbine) ventilators
In August 1997, the University of Technology in Sydney, Australia conducted tests on ALL turbine roof ventilators on behalf of the Australian consumer magazine 'CHOICE'.
The opinion of the magazine was published in November 1999 under "Spinning Hot Air"
It must be noted 'CHOICE' did not have the WINDWORKER tested and a challenge was issued to 'CHOICE' for a monitored comparison test between the WINDWORKER and the magazines selection of insulation. It was not accepted but still stands.
The following graph pertains to the ventilators tested and the results as compared to a 200mm open hole. This information was never published.
It has been shown that when different metals come in contact, there is often the possibility that corrosion through electrolysis or other forms such as acid rain, can deteriorate life of the products. Extensive tests have been carried out by metal organisations such as BHP to examine the consequences from this action.
With most roof ventilators being manufactured with aluminium, there lies a large potential for this material to react with roof cladding on a host structure. It may not happen today, but it can happen.
Saffir - Simpson Hurricane Scale
