Princípios da sustentabilidade em diferentes métodos construtivos: análise do viés econômico

Abstract

Since the beginning of the last century, especially with the industrial revolution, where there was an increase in population, the first technologies, such as machines, roads, large factories, etc. began to emerge. With it, there was a need for more comfort and quality of life for people. This breakthrough has been causing serious damage to the environment, many of which are irreversible, such as water scarcity and global warming and one of the main causative agents is the construction industry, where it is responsible for emitting about 50% of carbon dioxide in the atmosphere. Nowadays man is worrying more about these factors and seeking alternative solutions to these problems, such as the sustainable use of materials, reducing the use of natural resources and generation of waste. In this thought, the use of the structural masonry system is being studied as a more sustainable concept for the works, with the purpose of reducing costs and optimizing the building. The structural construction system of ecological bricks of cement soil is also another alternative, even more sustainable than the traditional ceramic blocks. The present work deals with the comparison of costs through an analytical budget between the construction systems of conventional masonry, structural masonry of ceramic brick and structural masonry of cement soil for the employment of popular dwellings. It was observed through the results that the construction system of cement soil had a great advantage over the other two systems, with a reduction of costs of up to 34.28%, reduction of work time of up to 51.04% and reduction of cement consumption Of up to 61.79%. The conventional construction system presented the highest cost, the highest working time and higher consumption of cement.
