Avaliação do ciclo de vida de uma edificação através da adequação de resultados de software com interoperabilidade BIM á realidade de uma construtora localizada em Fortaleza,Ceará

Abstract

The quantitative analysis of buidings´ sustainability is a task thst is considered to be, in general ,complex and requires time and effort .Especially in Brazil ,where there isn´t a large life cycle inventory database and the direct use of a non-native life cycle inventory data might produce errors due to divergences on countries´building typology. Thay being said,this project presents a life cycle assessment (LCA) of a construction company´s building located in Fortaleza,CE(Brazil), through the adequacy of software with BIM interoperability (Tally) on the purpose of presenting a simplified LCA calculation tool that can be used in the initial project phases ,using budget data as input. The methodology was subdivided into four main steps according to the basic principles of NBR ISO 14.040: 1) delimitation of the scope and limitations; 2) data collection; 3) creation of the LCA calculation tool; 4) Results´ comparison and discussion. The inventory data was collected through a BIM model of the analyzing building. Afterward, data were extracted for the creation of lhe LCA calculation tool and the software with BIM interoperability results was done as well. On the results,it was observed that the walls system was the major contributor on all impact categories except ´Acidification potential and ´Ozone Depletion Potential ´ and that materials that have burning processes on weigt more on the environmental impacts of a building.moreover elements that have cement on their composition have a great influence on all impact categories Lastly, it was noticed that to use of software with BIM interoperability it is necessary specific LCA adaptations to the model in order to increase results reliability.
