Achieving the net zero emissions target that was set in the Paris Agreement to mitigate the risks of climate change seems increasingly difficult as countries and sectors of the economy are falling behind the expected trajectory. The building and construction industry, as one of the main contributors to global emissions, has an essential role to play toward this aim. Net zero emissions target has been introduced to this sector as well; however, achieving it is a very challenging and complex task. Many studies have been undertaken on implementing different measures and strategies to reduce the industry’s carbon footprint. These studies identified many challenges and barriers in transforming the industry. This paper aims to provide a systematic review of challenges that organisations face in delivering new net zero emissions buildings. The relevant journal articles published since the Paris Agreement were identified and analysed using mixed-method data analysis, including quantitative (science mapping) and qualitative (thematic) analysis. The result showed increased attention to the subject over this period, with China, the UK, and Australia being the top contexts for research. The most discussed groups of barriers were “economic”, “knowledge”, and “technical”, respectively, followed by “organisational”, “market”, “technological”, and “legal” barriers.

This paper describes an empirical experiment of Internet of Things (IoT)’s integration in the Post-Occupancy Evaluation (POE) process. The experiment aimed to trial a novel IoT approach to enabling building user responsiveness to prevalent IEQ for individualised comfort. The purpose is to provide a system that mitigates a common issue of centralised air conditioning that limits occupants’ control over their immediate environment. To achieve this, an IoT platform was developed with smart IEQ monitoring sensors and wearable devices and trialled with PhD researchers in a shared university workspace. The findings provided empirical evidence of IoT’s enhanced benefits to improving user control over their individual comfort and enabling positive energy behaviour in buildings. Specifically, the IoT system provided real-time insight into CO₂ concentration data while enabling responsive occupant interaction with their immediate environment and at-the-moment mitigation actions. Outputs of the experiment showed that the perceptions of participants about the stuffiness of the air, productivity, and healthy environment were significantly better after taking the mitigation action compared to before. Also, we found a significant relationship between measured CO₂ concentration readings and perceived air stuffiness (p = 0.004) and productivity (p = 0.006) and a non-significant relationship between CO₂ concentration readings and perceived healthy environment (p = 0.058). Interestingly, we observed that irrespective of the similarities in recorded CO₂ concentration readings being within acceptable ranges (632–712 ppm), the perception of air stuffiness significantly differed (p = 0.018) before and after the mitigation actions. The effectiveness of the developed IoT platform was evidenced as most of the participants found the process very easy to participate in with little interruptions to their work as little time was consumed. The results are useful in modifying approaches to building occupant comfort and energy behaviour in commercial and residential settings.

This study presents the digital documentation of traditional Fijian architectural heritage through an in-depth investigation of the bure , Fiji’s indigenous house, focusing on three distinct bure types in Navala village. Although the bure has long been recognised for its cultural significance and demonstrated capacity to respond to environmental conditions and natural hazards, its continued construction is increasingly limited by urbanisation, shifts in contemporary building practices, and the progressive loss of traditional craftsmanship. These changes highlight the need to preserve not only the remaining physical examples of bure houses, but also the construction knowledge embedded within their form and assembly. This study applies an integrated digital documentation workflow combining terrestrial photogrammetry, UAV-based imaging, and LiDAR scanning to record selected bure houses that remain in good structural condition. The acquired datasets were processed to produce registered point clouds with millimetre-level accuracy, high-resolution mesh models, three-dimensional visualisations, and CAD drawings suitable for long-term digital archiving. Together, these outputs provide a detailed and verifiable record of architectural geometry, construction details, and spatial organisation. While the primary objective of the research is documentation, the resulting digital archive establishes a foundation for future applications, including post-disaster reconstruction, the transmission of construction knowledge, and improved structural understanding to support hazard response in disaster-prone contexts. The study is novel in that it presents the first high-resolution digital documentation of these bure types, explicitly situating traditional Fijian architecture within discussions of disaster resilience and proposing a transferable documentation workflow for Pacific Indigenous heritage. The outcomes offer a valuable resource for researchers, educators, conservation practitioners, policy makers, and disaster response agencies concerned with both cultural heritage preservation and resilience-oriented planning.
