As global warming worsens, reducing energy use is becoming increasingly crucial. In recent years, 34% of the world’s energy use has been consumed by buildings. Therefore, improving building energy efficiency is essential for halting climate change and promoting sustainability. In this regard, Building Information Modeling (BIM) is steadily emerging as a valuable tool for promoting energy efficiency. This research adopts a systematic review approach, and 87 articles were included for review. This research identified seven areas in which BIM plays a role in energy efficiency. For each area, workflows for the adoption of BIM were explored. Meanwhile, the advantages and disadvantages of each adoption of BIM were critically examined. In conclusion, visualization is the most helpful feature of BIM and is beneficial for almost all applications. In addition, software compatibility issues and high initial setup costs are the most common drawbacks of adopting BIM. This research makes several contributions to the literature. First, the results of this study help provide a better understanding of the importance of BIM in energy efficiency improvement. Secondly, our research supplements the energy field that identifies seven BIM use categories. Thirdly, this article critically examines the use of BIM in the building energy field.
Prefabrication is increasingly recognized as a sustainable construction practice, with the efficiency of prefabricated component (PC) production lines playing a critical role in its success. However, supplier selection for PC production lines has become more complex due to evolving industrial demands, uncertain supply chain conditions, and operational complexities. This study addresses this gap by developing a lean-based AHP–improved VIKOR decision-making framework to enhance the supplier selection for PC production lines. The framework integrates advanced lean principles with universal and specific evaluation criteria, identified through a comprehensive literature review and expert interviews. Its validity was tested via a real-world case study with Yizhong Construction Co., Ltd., Tianjin, China. The results show that the three suppliers are ranked as Zhongjian > Tianyi > Xindadi, where Zhongjian is the best supplier in this case study, with a VIKOR index of 0.156. The findings show that the developed framework can improve the supplier selection efficiency by aligning with lean principles and enhancing the performance of PC production lines. By addressing the challenges of PC supplier selection, this study provides a practical tool to advance the adoption of prefabrication in construction. Furthermore, it contributes to the development of the PC industry by offering a robust method for the selection of suitable suppliers, which can help to optimize the production efficiency and support sustainable practices in construction.
