Economía circular en la construcción y ciclo de vida de sistemas estructurales no tradicionales : determinación de acv del sistema estructural de paredes portantes de hormigón celular.

Abstract

This project addresses the need to change the linear production paradigm in construction, which often ignores environmental concerns. The answer to this issue is the circular economy, which introduces reuse into the production cycle, counteracting the use-and-dispose mentality. The main objective of this Curricular Integration Work is to apply life cycle analysis (LCA) according to ISO 14040 to an unconventional structural system: load-bearing walls of cellular concrete in San Fracisco’s project and to evaluate the environmental impact generated by the main materials used in its construction. Using computational tools, the architecture and the structural system are modeled, where the quantities of work required to establish the environmental response of the building are determined. These data are entered into the OpenLCA software, which executes the LCA using environmental impact categories from CML-IA baselines and the European Life Cycle Reference Database (ELCD). Finally, PriMus software is used to estimate the benchmark price of the main building items and to determine a benchmark budget for the construction of the project. The main purpose of this project is to evaluate the economic and environmental feasibility of a non-conventional aerated concrete load-bearing wall system. The objective is to achieve cost efficiencies within the budget and to reduce the environmental impact by minimizing the amount of construction materials used.
