Análise comparativa do consumo energético agregado para sistemas construtivos civis em aço e concreto armado para um edifício industrial de pequeno porte

Abstract

The construction industry is directly linked to Brazilian development process, being an industry with great economic importance representing large fractions of Gross Domestic Product in our country and contributing to participatory human and social development. In recent years, the construction sector has gained special prominence with increasing government incentives and public policies for social development and national infrastructure. On the other hand, the construction industry is also responsible for large CO2 emissions, waste generation and environmental degradation, employing processes of intense energy consumption in the production of the raw materials industry, generating frequent debates about economic growth and sustainability. The works represent a small majority of the projects executed by construction, which are mostly designed for concrete or steel. Currently under construction investments seek a quick return on investment, requiring agility deadlines and competitive costs, thereby using precast structures in reinforced concrete and steel structures reach a large portion of the current market buildings. Thus, the studies conducted by this research has the main objective to identify the aggregate energy consumption for an industrial building small, by analyzing the energy consumption used in the production of the main raw materials of the buildings, the portland cement and steel. The analysis seeks to present the energy consumption used in the construction of an existing precast existing building small reinforced concrete, and by reproducing the original barn, estimate the energy consumption used to implement this in metal frame building. With bases on data collected through the literature review, it was possible to find approximate aggregates to portland cement and steel used in the main structure of the building energy consumption results, obtaining important results and conclusions.
