By means of the experiences and the researches recently developed that show an integrated approach to the problem, it is possible to draw a series of indications for an ecological management of the urban water cycle. However, it is crucial to remember that the task of the architect is also to experiment an integration between eco-technologies for the re-naturalisation of the cycle of water and the image of the building. It is possible, actually, to use technologies related to water, tailored to the local conditions, for a result that integrates functionality, aesthetics, environment sustainability and thermal comfort.
