Construction material consumption is greater than any time in history. Australia produces approximately 30 million tonnes of finished building products each year, with over 56% of this quantity, by mass, being attributed to concrete and a further 6%, steel. Globally, 23 trillion kilograms of concrete alone is consumed annually, with growing population driving increasing demands. This study assesses the environmental performance of various concrete slab systems. Historically, the focus of environmental performance in buildings has been Operation Energy (OE) requirements, however Zero Energy Buildings (ZEB) are changing this. Specifically the study investigates the environmental performance of concrete structures varying design parameters and construction techniques to optimise its embodied energy (EE). These structures are designed in accordance with all relevant Australian codes and standards. The various slab systems investigated include: beam & slab, flat slab and flat plates while concurrently considering the use of conventionally reinforced and post-tensioned construction methods. Designs were compared in terms of EE outcomes given fixed design criteria, with results indicating reductions between 23.7% and 49.1% when utilising post-tensioned construction methods.Griffith Sciences, Griffith School of EngineeringFull Tex

This paper presents a systematic literature review of the impact of emerging technologies such as Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), and gamification on student engagement, learning outcomes, and employability in Built Environment (BE) education. This review covers studies conducted between 2013 and 2023, utilizing the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) framework. From an initial pool of 626 studies, 61 were identified and rigorously analyzed. The findings reveal that these technologies significantly enhance student engagement by providing immersive and interactive learning experiences that bridge the gap between theoretical knowledge and practical application. Furthermore, their use is shown to improve learning outcomes by facilitating a deeper understanding of complex concepts and increasing student motivation. In terms of employability, the integration of digital tools into BE education equips students with the requisite skills that are increasingly demanded in the modern workplace. However, the study also identifies several challenges, including high costs, limited resources, and the need for extensive faculty training, which act as barriers to the effective implementation of these technologies. Despite these challenges, this review underscores the transformative potential of digital technologies in BE education. This study is significant as it synthesizes recent evidence to highlight the critical role of digital technologies in reshaping BE education. It offers practical recommendations for educators and policymakers to enhance teaching and learning practices. Providing pathways for integrating these technologies into BE curricula, this study aims to inform future research and pedagogical strategies, ultimately contributing to the development of a highly skilled and adaptable workforce.
