The Praille-Acacias-Vernets suburb, located in Geneva, Switzerland, is today considered as an outworn city area (2.3 km(2)). It consists of parking lots, industries, businesses and marshalling yards. The Geneva Government decided to remodel this suburb to effectively allow for city growth while complying with the highest energy efficient and environmental standards in urban development. A masterplan was accepted in spring 2007. It did not take into account the various energy and natural resources of the area at that stage.
