Análise do consumo energético de uma obra com uso de estratégias de eficiência e ferramentas BIM: terraplenagem e estruturas de concreto armado

Abstract

A building erection involves high energy expenditure, being like phases of earthwork and execution of structures as they generally represent the greater consumption, which is also reflected directly in costs. Thus, from the generation of a pavement building model in a residential typology and with the BIM, the objective of this work is to evaluate the approximate energy consumption in the earthwork phase and in the execution of concrete structures, considering they represent the greatest demand energetics on site. With the case study, it is intended to demonstrate the strategy, within the execution planning of a work, which is able to reduce the expenditure of fuels and electricity. As methods, we divided the development of the work into three main stages, starting with a proposal of the model of building of pieces, selecting as phases more energy-intensive based with no proposed model, generating a simulation in 4D to allow a construction analysis and by end, studying possible strategies for reducing energy consumption. It is understood that this work can aid in demonstrating the use of BIM for a decision of the designer and builder, in the best of energy efficiency in the phases that most involve energy consumption in a construction.
