Abstract
El presente estudio se centra en el análisis de ciclo de vida – ACV de un edificio residencial típico de la ciudad de Lima (3 sótanos, 9 pisos más azotea), donde se evaluó el carbono incorporado (etapa de producto: A1 – A3) de un edificio convencional en hormigón armado -erC(HA)- y se comparó a una propuesta híbrida en hormigón armado y madera masiva erH(HA+CLT)-, la categoría de impacto evaluada fue: potencial de calentamiento global (PCG). Los resultados de las dos modelaciones mostraron que el edificio híbrido impacta con una menor huella de carbono; para el escenario 1 donde no se considera el almacenamiento de carbono biogénico, se redujo en un 24.87%, con 176.37 kgCO2e/m2 de superficie, y para el escenario 2, donde si se considera el biocarbón, se redujo aún más en un 138.86%, con -91.23 kgCO2e/m2; en comparación con el indicador que resulta del edificio convencional, con 234.75 kgCO2e/m2. Los resultados muestran que integrar elementos constructivos en madera masiva es beneficioso para el medio ambiente.
This study focuses on the life cycle analysis - LCA of a typical residential building in the city of Lima (3 basement, 9 floors plus roof terrace), where the embodied carbon (product stage: A1 - A3) of a conventional reinforced concrete building -erC (HA)- was evaluated and compared to a hybrid proposal in reinforced concrete and mass timber -erH (HA+CLT)-, the impact category evaluated was: global warming potential (GWP). The results of the two models showed that the hybrid building impacts with a lower carbon footprint; for scenario 1 where biogenic carbon storage is not considered, it was reduced by 24.87%, with 176.37 kgCO2e/m2 of surface, and for scenario 2, where biochar is considered, it was further reduced by 138.86%, with -91.23 kgCO2e/m2; compared to the indicator resulting from the conventional building, with 234.75 kgCO2e/m2. The results show that integrating construction elements in solid wood is beneficial for the environment.
