COMPARATIVA ENTRE SISTEMAS CONSTRUCTIVOS DE HUECOS PARA ASCENSORES EN FUNCIÓN DEL ANALISIS DEL CICLO DE VIDA

Abstract

ABSTRACT: This paper compares environmental impact of traditional construction systems of hoistways made for elevators in residential building sites, using techniques based on Life Cycle Analysis (LCA), calculation of Carbon footprint, quantifying total energy consumption and emissions in the material used as well as building and recycling of all materials in use. Furthermore, other environmental variables directly related with environment sustainability will be studied. We have simulated the analysis with a time frame of 50 years, 100 km track average for the transporting materials and 15 km residues distance average from rubbish dump. The ceramic brick wall has proved to have the best behavior from building and maintenance cost, risk in health and safety and intensive use of workers point of view, variables all related with economical building aspects. On the other hand, from sustainability point of view it is proved that the ½ ceramic brick walls with rock wool insulation and one final layer with ceramic brick had the best environmental sustainability behavior. It proved that from an environmental sustainability point of view, traditional materials and masonry construction systems are less polluting than concrete construction systems, showing advantages in building design when the sustainability concepts are applied in materials selection and construction techniques all over LCA.
