Indicadores gerenciais e de interesse ambiental na construção civil: o caso de edíficios residenciais verticiais

Abstract

On the national scene, the construction industry has a great relevance in the economy. Despite this benefit, the constructions generate some environmental impacts, causing a high ecological footprint, which refers to the impact of that area on the resources that were used. One way to manage these impacts is to measure some parameters. So, the objective of this work is to determine the indicators of water consumption, electric power consumption and the generation of Constrution and Demolition Waste (CDW), in a residential building project. The object of study is located in the city of João Pessoa – PB. The methodology of this work was based on the calculation of two indicators, the first one take into account the built area, the second one was based on the number of men and hours worked on the construction place. This work found 0.76m³/m² and 23.86 l/man.hour for water consumption. For the electricity consumption, were calculated 10.45kWh/m² and 0,3289kWh/man.hour. As for the CDW, a generation of 155.08 kg/m² and 4.92 kg/man.hour was identified. Finally, for the CDW - class A, there was a generation of 128.43 kg/m² and 4.06 kg/man.hour. After doing the necessary calculations, it was observed that water and energy consumption are above the values already found in the literature. For waste generation, it is within the range established in another study.
