Revolutionising BIM-based Digital Learning: Integration of Mixed Reality with Digital Twin Technology for Carbon Audit Training

As global awareness of climate change grows, the construction industry has become a significant contributor to carbon dioxide emissions, accounting for approximately 39% of global carbon dioxide emissions. There is increasing pressure on this sector to adopt sustainable practices, particularly in the context of energy management and carbon audits. Due to these challenges, the trend of digitalisation is accelerating, with technologies like Building Information Modelling (BIM) and the Internet of Things (IoT) at the forefront. The construction industry can enhance sustainability through improved data collection, analysis, and decision-making by utilising these technologies. This TDG project aims to develop a Digital Twin (DT) framework to improve energy management and facilitate carbon auditing within a built-asset. Integrating Mixed Reality (MR) and BIM technologies, this project offers students practical experience with innovative methodologies aligned with sustainable practices. This initiative strengthens the connection between research and teaching by incorporating advanced research outcomes into the curriculum. This project will develop an interactive dashboard that is accessible via MR devices. The collaborative dashboard design can be accessed by up to two users via the MR application, facilitating joint efforts to audit carbon emissions. Additionally, the application will enable users to manipulate virtual objects and optimise energy efficiency measures, displaying real-time data and anchoring virtual objects in the real world. This educational initiative will give students valuable experience in emerging technologies, including DT, MR, and IoT. Students will gain a deeper understanding of sustainable energy management and technology's role in environmental conservation through active participation in this project. This proposal also seeks additional funding to develop an innovative pedagogical tool designed to equip the next generation with skills necessary to tackle contemporary challenges related to energy efficiency and carbon footprint reduction. Through a practical and digital learning environment, students will develop essential skills that prepare them for leadership roles in sustainable development. Australia is a leader in carbon auditing due to its robust regulatory frameworks, stakeholder engagement, and innovative governance initiatives. As a result, the country has made significant contributions to environmental management. Professor Kenneth Yiu, a Professor of construction at UNSW Sydney, will jointly deliver this project. This collaboration will enhance CityUHK's carbon management education, positioning it at the forefront of international best practices.
