AVALIAÇÃO DO CICLO DE VIDA DE DIFERENTES ENVOLTÓRIAS PARA HABITAÇÕES DE INTERESSE SOCIAL EM FLORIANÓPOLIS

Abstract

The main objective of this work is to select the set of construction components with the lowest environmental impact to use in social interest houses in Florianópolis by means of life cycle assessment (LCA). An architectural design was developed and four walls, three window frames and three roofs were tested. For the walls it was considered the use of ceramic brick with coating, adobe brick with lime earth mortar and autoclavated concrete celular blocks with and without coating. Wood, aluminum and PVC were used for the window frames. For the roofs it was considered fibercement and ceramic tiles with wooden ceiling or solid concrete slab. The simulations were performed using the EnergyPlus program; the results were used as input data for the LCA. The set of construction components that presented the lowest energy consumption was the wall composed of autoclavated concrete celular block with coating, window frames made of wood and roof composed of ceramic tile with solid concrete slab. The LCA was performed using the SimaPro program. It was concluded that the set with the lowest environmental impact was composed of adobe brick wall, wood frames and roof composed of ceramic tile and solid concrete slab. In addition, the set with the lowest environmental impact did not coincide with the lowest annual energy consumption obtained by means of simulation.
