Avaliação de emissões de CO2 na construção civil: um estudo de caso da habitação de interesse social no Paraná

Abstract

The civil construction industry is one of the more important in the Brazilian scenery, not only by the big quantity of financial resources that move and generation jobs, but by the great energy volume and natural resources that utilize. Actually it’s discuss, in global level, actions for the sustainable development as The Kioto Protocol that aspire to reduce the emissions levels of the greenhouse gases. The civil construction sector, with rare exceptions in The Brazil, is in “the margin” of process to reduction the gases emission that provoke the global warm. In this researches is analyzed how the social construction developed in The Paraná State, só important and necessary faced with the great number of families without home, has contributed to the greenhouse gases emission, using building materials with high indices of emissions in its production process and in the material transportation system that use the road transport to do the houses in different places in The Paraná State. Through bibliographical revision of the main building material process systems utilized in a popular project model more use in that State, was possible quantify the CO2, main greenhouse gas that provoke the global warm. Finally concluded that is necessary a gradual change in the construction and logistic model through systematic action look for the reduction of the environmental impact of that important sector.
