A BIM-Based Optimization Model for Enhancing Building Energy Performance in Green Construction

The construction sector plays a significant role in global energy consumption and environmental degradation, necessitating innovative approaches to improve building energy performance in green construction. Building Information Modeling (BIM) has emerged as a powerful platform for integrating design, analysis, and decision-making throughout the building lifecycle. This study proposes a BIM-based optimization model aimed at enhancing building energy performance to support green construction objectives. The proposed model integrates BIM with building energy simulation and optimization techniques to evaluate and optimize key design parameters, including building orientation, envelope characteristics, material selection, and mechanical system configurations. The model is validated through a case study of a building project, where energy performance scenarios are simulated and compared. The results demonstrate that the BIM-based optimization model can significantly reduce annual energy consumption and improve overall energy efficiency compared to conventional design approaches. The findings highlight the effectiveness of BIM as a decision-support tool for energy-efficient design and provide practical insights for architects, engineers, and project stakeholders in implementing green construction strategies. This research contributes to the development of integrated BIM-based methodologies for sustainable building design and supports the advancement of energy-efficient construction practices.
