Simulação exergoeconômica de aquecimento solar residencial integrado à metodologia BIM

Abstract

This work aims to perform an exergoeconomic simulation of a residential solar water heating system using BIM (Building Information Modeling) technology. The choice of this topic is justified by the growing demand for sustainable and efficient solutions in the construction sector, particularly in the context of the energy crisis and the search for alternatives that combine cost-effectiveness with environmental responsibility. The adopted methodology consisted of creating a three-dimensional model of a standard residence with an integrated solar heating system, using Revit software to represent it within the BIM environment. Key components such as solar collectors, piping, thermal reservoir, and consumption points were included in the model. The simulation used real solar radiation and ambient temperature data to estimate system performance over time. In parallel, an exergoeconomic analysis was carried out, involving the assessment of exergy flows throughout the system and the correlation of those flows with economic costs, including acquisition, installation, operation, and maintenance. The results showed that integrating BIM modeling with exergoeconomic analysis enables the identification of critical performance losses, allowing adjustments in design and sizing to maximize exergy efficiency and reduce the cost of useful energy. It is concluded that the adopted approach provides an effective tool for the technical and economic evaluation of solar heating systems in residential buildings, supporting more sustainable and well-informed design decisions. Furthermore, this type of simulation has strong potential for practical application by engineers and architects aiming for more efficient and economically viable buildings.
