فن آوری های مقاوم سازی خودهمیاری برای ساخت مسکن ارزان قیمت: مطالعه موردی ویلا نوو اورو پرتو، برزیل.

The paper presents low-tech and low-cost solutions such as, in particular, self-help retrofitting technologies, to improve the quality in spontaneous settlements (favelas) which arise close to the major Brazilian towns. In particular, a critical analysis of the favela Vila Novo Ouro Preto in Belo Horizonte has been elaborated, highlighting both social, cultural and technical aspects to design suitable technological components to be adopted in order to improve environmental comfort. The study has been developed in order to meet people needs and expectations so as to guide planning and design perspectives aiming at improving the quality of life in a sustainable socio-cultural way. The contribution suggests a selection of interesting techniques and processes achievable in self-help construction; some of them are quite innovative since they use in a new and different way recycled materials and products, thus boosting economic growth and social development.
