Resumen

Climate change is one of the main problems of our century and Greenhouse Gas (GHG) emissions are its main cause, considering that the construction industry is one of the biggest GHG emitters worldwide, it is imperative that this sector applies effective sustainability practices; currently there are various proposals for sustainability practices have been presented for the building operation stage, however these are limited because they are not framed within a holistic vision of the problem that includes an analysis of the entire life cycle of the building, in this sense, the present investigation, through a review of GHG quantification study cases and a theoretical, methodological and application comparison, proposes a carbon footprint calculation methodology that adapts to the context of Peruvian construction, takes as reference the framework of the life cycle analysis (LCA) that integrates with the Building Information Modeling (BIM) as a technological tool for the management of the diverse and large amount of project information required by the LCA. In order to validate the proposed methodology, GHG calculation was performed for the structures stage of the construction of an educational building, allowing to simulate the construction process and estimate that the building will generate 305.44 KgCO2eq/m2 in its construction stage from cradle to door, where 92.5% emissions correspond to the materials manufacturing stage and 57.5% incidence of this stage corresponds to ready-mix concrete since this resource has a long supply chain.
