Design and Implementation of a Digital Twin Visualization Platform for a Residential Building

<p dir="ltr">The building sector has drawn global attention due to its high energy consumption and significant environmental impact, making its energy efficiency improvement a crucial research focus. This study developed a digital twin visualization platform for one residential building in Australia, aimed at optimizing users’ energy usage patterns by providing real-time insights into indoor environmental conditions, ultimately achieving energy-saving goals. By integrating Building Information Modelling and IoT technologies, the platform allows users to explore the 3D building layout and view realtime data, giving a full overview of the building's operation for better adjustments. The visualization platform includes a 3D building model and a user interface panel with three main modules: real-time data display, temperature trend charts for selected time ranges, and real-time temperature monitoring of different indoor areas. The latter two modules feature interactive options, enabling users to engage with the data. By showing real-time and historical data, the platform helps users make informed choices to lower energy use. Experimental results indicated that the system could enhance the accessibility and comprehensibility of building data, supporting energy-saving choices. This study demonstrates the potential of digital twin technology in improving building energy efficiency and user awareness, offering an effective future to achieve sustainable building operations.</p>
