This paper explores the integration of smart building technologies such as Internet of Things (IoT) sensors, automated HVAC systems, and energy management tools—within public universities in KwaZulu-Natal, South Africa. Set against the backdrop of increasing sustainability demands and the need for improved operational efficiency, the study investigates both the potential benefits and the persistent challenges linked to implementing such innovations in higher education environments. Although these technologies can significantly enhance energy efficiency and lower running costs, universities often face hurdles including steep initial investment costs, system integration difficulties, and ongoing budget limitations. Based on a systematic review of relevant literature, the research identifies critical barriers to adoption while also outlining emerging opportunities for progress. Early insights suggest a slow but noticeable uptake of smart systems, despite ongoing issues related to funding and infrastructure capacity. Nevertheless, the study points to practical strategies—such as engaging stakeholders, offering capacity-building initiatives, and launching pilot projects as effective ways to support a more sustainable and technologically adaptive approach to campus management. Ultimately, the findings emphasize the role of smart building technologies in driving long-term transformation in university operations.
