“…These systems, while effective in maintaining desired temperatures, are notorious for their energy consumption. The primary reason is their reliance on mechanical cooling, which uses compressors and refrigerants to achieve cooling, often consuming as much energy as the servers themselves (Enteria et al, 2020).…”

The rapid proliferation of digital services and the surge in cloud computing have significantly increased the demand for data centers worldwide. As these facilities consume vast amounts of energy, there is growing concern about their impact on the environment, particularly in relation to climate change. This paper reviews the extent to which data centers contribute to global greenhouse gas emissions and examines the energy efficient strategies being employed to mitigate their environmental footprint. Key findings indicate that without intervention, data centre emissions could rival those of major global industries. Fortunately, innovations in cooling technologies, architectural design, renewable energy sourcing, and hardware efficiency have shown potential in reducing energy consumption. The paper also underscores the importance of a holistic approach that encompasses both technological advancements and policy measures for meaningful progress. In conclusion, while data centers are indeed a source of climate concern, the ongoing advancements in energy-efficient strategies provide a promising pathway towards a sustainable digital future.

“…Indoor thermal comfort, largely gauged by factors such as ambient temperature, humidity, and air velocity [9,10], bears profound implications, stretching from the quotidian experiences of individuals to overarching paradigms of global energy consumption and environmental conservation [11][12][13][14][15][16]. Building energy demands are purported to constitute nearly 40% of global energy intake, with the bulk channelled towards building heating, cooling, and ventilation.…”

As urbanisation intensifies, an increased proportion of human activities is observed to be conducted indoors, amplifying the imperative of a superior indoor living environment. Among the various facets influencing indoor environmental quality, thermal comfort emerges as a pivotal factor influencing both physical and mental well-being. While predominant research methodologies predominantly employ empirical evaluations, the nuanced impacts of interior architectural structures on airflow and temperature distribution often remain unaddressed. Furthermore, rigorous simulations based on fluid dynamics are frequently absent from these assessments. In this study, the interplay of heat transfer and ventilation within interior architecture is meticulously examined. A novel research framework is introduced, encapsulating evaluations of human thermal comfort in ventilated interiors, intricate indoor airflow simulations predicated on fluid dynamics, and the pioneering design strategies for optimised hollow and ventilated architectural interior wall systems.
