Análise de soluções sustentáveis para moradia unifamiliar: comparativo de custos com construções tradicionais

Abstract

The population growth, plus a rapid urban development, highlights a series of environmental problems, such as the energy crisis, society's unsustainable consumption patterns and the impacts resulting from the generation and disposal of solid waste, etc. In Brazil, the construction industry is one of the main economic and job-creating activities, but also represents one of the human activities that most causes environmental damages. Thus, when thinking about its importance in the economic sector, in order to reduce the negative effects of the practice of civil construction on the environment, the implementation of sustainable practices is justified. There is a growing concern about environmental issues in different spheres of society, making one of the main challenges of the XXI century to ensure economic development and as the same time minimize environmental damages. The search for ecologically and sustainable solutions has become a daily procedure of large companies, especially those aimed at commercial construction. However, in the sphere of residential constructions, the implementation of sustainable techniques and technologies is still considerably out of date. Thus, by doing this research, we sought to find the main sustainable solutions and technologies currently being used and analyze the costs for implementing them in a single-family residence project. It was observed that, either due to the advancement or diffusion of the technologies used, most of these have been showing a reduction in costs. Despite the delay on the insertion of these technologies in the residential construction sector, the advances are promising, with the possibility of bigger use of these even in small projects
