Reimagining sustainable design: Leveraging 4IR and virtual reality in architectural engineering education

This study investigates the integration of Virtual Reality (VR), specifically the Oculus Quest 3, within architectural education to enhance sustainable design practices. Using a first-principal approach to design thinking, the research explores how immersive VR environments can improve spatial cognition, support iterative design, and encourage environmentally-conscious decision-making. The study was conducted with ten postgraduate architecture students at Nelson Mandela University, who engaged in a small house design project within a virtual design studio. Students were able to create 3D models, explore them at a 1:1 scale in VR, and receive immediate feedback to refine their designs. Findings indicate that VR significantly enhances students’ spatial awareness, allowing them to better understand proportions, relationships, and functionality within their designs. The immersive environment also supports rapid design iteration, enabling students to test multiple design options efficiently and make real-time adjustments. Moreover, VR facilitated the integration of sustainability principles, as students could visualize energy flows, natural lighting, and material impacts, leading to more environmentally-informed design decisions. Participants reported heightened engagement and satisfaction with the design process, noting that the interactive and experiential nature of VR made learning more intuitive and enjoyable. The results suggest that VR offers transformative potential for architectural pedagogy. By incorporating immersive technologies into the design studio, educators can provide a more holistic, hands-on learning experience that develops spatial understanding, creativity, and sustainability awareness. This study highlights the importance of integrating VR into architectural curricula, preparing students to navigate the increasingly digital, collaborative, and sustainability-focused demands of contemporary design practice.
