The design by Maria Andrea Triana, Roberto Lamberts and Marcio Antonio Andrade of LabEEE-UFSC, Florianópolis, Brazil, for a solar water heating and rainwater tower was applauded for developing an innovative and economical solution to the widespread lack of public infrastructure in poor urban areas.
The “sustainable tower” provides rainwater harvesting, potable water storage and solar water heating in an integrated unit that can be installed within new or existing dwellings, and thus delivers a substantial improvement in the daily living conditions of residents.Media release – Holcim Awards honor sustainable construction in Latin America » más información (Spanish) » leia mais (Portuguese) »
This project proposes an innovative and economical solution to a very common problem related to low income family housing. Due to the lack of public infrastructure, residents do not have ready access to drinking water, sewage systems and energy supply. The most serious shortcoming is potable and hot water, basic needs that are covered by the sustainable tower which provides rainwater harvesting system, potable water storage tank and solar water heating device in an integrated structure.
The tower itself is composed of prefabricated rings made of ferrocement. The modular system, adaptable to different needs and local situations can be incorporated in new houses as well as in existing ones and allows for energy efﬁciency and rational use of water. The smart combination of existing and proven technologies has a great potential for industrial production and realizing the associated economies of scale to reduce costs of production per unit. Overall this is an innovative concept with a substantial impact on the daily living conditions of poor families and with a great potential for transferability.See more
There are simply too few houses for low-income families in Brazil. State housing programs work to decrease the deficit by providing basic standard homes. Specialists used these initiatives to bring technology and innovation into the equation – a Solar water heating and rainwater tower provides a sustainable solution to domestic water storage and heating needs.Download project entry poster (PDF, 1.57 MB) »
