Resumo
Despite the constant technological advancement of humanity and the increased efficiency of production inputs, we can still face with situations of extreme poverty and need throughout the world. In Brazil the reality is not different, where we can identify a housing deficit of more than 5 million residences since 2007. In this way, public policies were created that aim to reduce this index. The present work seeks in this context, environmental solutions that can mitigate the impacts generated by these enterprises. Therefore, we suggest the application of Rainwater Harvesting Systems (RWH) in social housing (SH) and the simplified Life Cycle Analysis (LCA) as a tool to be used in these issues. For the bibliographic review, was applied the methodology of Systematic Literature Review (SLR) as an instrument for the efficient search of bibliography. Through this search it was possible to verify the breadth of research that applied the LCA in RWH. The methodology proposed by Tavares (2006) and applied by Marinoski (2010) were adopted for the comparison between two scenarios of rainwater harvesting, an individual and a collective. In addition, two sets of inventory data were presented in this study. The first one comes from national data and the second from international data. The results were presented as 19 environmental indicators based on embedded energy (EE) and embedded carbon dioxide (EC) in the materials used in RWH and in the operation of the system. The indicators were used to make comparisons between the systems and it was verified that the collective scenarios are more environmentally friendly than the individual ones. This occurred because the operating EE and EC of the individual systems, presented values on average 4 times higher than those presented by the collective systems.
