“…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.

“…To our knowledge, apart from the few studies presented above, the hygrothermal behavior and life cycle analysis are not well reported on in the literature. S. Cao et al [10] and S.S. Sui Jiang et al [11] show the capacity of the Wufi Plus software for the study of the hygrothermal behavior at the building scale. WUFI Plus is an advanced commercial software that helps the user simulate the impact of the energy performance of a building by considering the effects of moisture and heat at the same time [11].…”

The adverse environmental impacts of building materials can be achieved by reducing the amount of cement in cementitious composites, specifically when incorporating wastes as partial replacement for Portland cement. In this work, we substitute cement with shell by-products while keeping useful specific properties. Scallop shells are good candidates to replace part of the Portland cement as they contain calcium and are available in abundance. We present an experimental and numerical study on the mechanics, hygrothermal behavior, and life cycle analysis of scallop shell concrete. In the fresh state, the replacement of cement by up to 10 wt.% of scallop shells does not significantly affect mortar properties. The results indicate that including 10% shells represents a decrease of up to 40% in the environmental impact, depending on the category of impact considered. Furthermore, the addition of Scallop shells makes the material more porous, leading to the facilitation of moisture transfer.
