Abstract:
The production of building materials plays an important role in determining the total environmental impact of building in this study, the impact caused by the production of materials used in a popular was assessed by means of Life Cycle Assessment. The Life Cycle inventory was developed using ecoinvent version 3.3 and 16 impact categories were assessed, using four different LCIA methods (CED, CML, ReCiPe and Usetox). The main materials that contribute to the impact categories considered were presented, as well as which activites and substances emitted (or consumed) have the major contributions to environmental impacts. Water consumption, resources depletion, particulate emission and land use are other relevant environmental impacts for construction. Some impact categories are related to activities for upstream the value chain, such as petroleum extraction. These differences must be considered when taking decisions for improving the environmental performance in the construction sector. Results also indicate a potential for simplification of the impact step, that could help the adaption of LCA in construction sector.
