主　　题：LCA environmental impacts social interest housing construction materials 

摘      要：Characterized by high consumption of natural resources and great generation of environmental impacts,civil construction becomes an important ally to the development of strategies for a more sustainable built *** this context,this article aims to evaluate construction systems of social interest housing and point out their participation in relation to total impacts,in addition to indicating the environmental impacts embedded in the construction materials present in these *** this end,a case study was selected to apply Life Cycle Assessment(LCA)methodology and assess impacts of the building materials used in a house of a social housing *** was applied to masonry,roof,coatings and floor *** scope adopted assesses impacts incorporated in construction materials,analyzing the stages of raw material extraction,materials production,transport to construction site,maintenance and materials *** life cycle inventory,Ecoinvent 3.6 database was used and environmental impacts were calculated using CML method with the aid of OpenLCA 1.9 *** general,results showed that the maintenance phase has the greatest environmental impact participation related to analyzed ***,it was possible to conclude that coatings and masonry systems were the ones that most added to total environmental impacts.
