BIM Implementation Challenges in NZEB Projects: Perspectives from Constructors

The construction industry consumes vast natural resources, which can be mitigated through sustainability initiatives like Net-Zero Energy Buildings (NZEBs). However, Building Information Modeling (BIM) implementation in NZEB projects faces challenges that hinder its widespread adoption. This study examines these challenges, and the knowledge and skills required to address them. Surveys and interviews with NZEB constructors reveal key barriers such as resistance to change, lack of expertise, and high training costs. Correlation analysis shows that reluctance to adopt BIM is strongly linked to knowledge gaps and financial constraints, highlighting the need for targeted training investments. Additionally, software incompatibility is a major issue, restricting collaboration and efficiency. The study identifies essential knowledge areas, including proficiency in sustainability-related analysis software, energy modeling, and BIM integration with performance simulation tools. Addressing these challenges requires investment in training, improved BIM software interoperability, and better industry-wide adoption strategies. Emerging digital technologies, including Artificial Intelligence (AI), offer potential solutions to enhance BIM workflows and decision-making in NZEB projects. These findings provide insights into BIM adoption trends and future technological directions, supporting sustainable construction and net-zero objectives.
