Abstract

The implementation of thermal insulation within the walls of building constitutes a pivotal strategy aimed at mitigating cooling loads and augmenting energy efficiency, particularly in tropical climate conditions. In the preceding decade, scholars have progressively utilized both empirical and computational methodologies to evaluate the efficacy of insulation under diverse environmental and material parameters. Aims:  This study undertakes a comprehensive review of methodological frameworks in the domain of thermal insulation research for building walls conducted between 2020 and 2024, with an emphasis on hybrid experimental design that integrate physical measurements with digital simulations to yield more accurate, dependable, and contextually pertinent data. Methodology and results: A systematic literature review (SLR) encompassing 52 scholarly articles was performed, categorizing the studies into four distinct classifications: field studies, laboratory-based investigations, digital methodologies (e.g., EnergyPlus, TRISCO, ABAQUS), and hybrid methodologies. Among these, digital experimentation emerged as the most predominant methodology, with EnergyPlus identified as the most frequently utilized instrument. Research employing hybrid methodologies demonstrated enhanced analytical rigor through cross-validation, versatile scenario exploration, and comprehensive thermal performance assessment. Conclusion, significance, and impact study: Combining empirical data with digital experimentation significantly improves the precision and contextual relevance of thermal insulation evaluation. Hybrid methodologies facilitate the simulation of prolonged or extreme conditions that are often impractical to physically assess. Calibrated digital instruments such as EnergyPlus, TRISCO, ABAQUS, Delphin, and COMSOL are particularly effective. Especially for tropical climates, hybrid methodologies offer a robust framework for improving the design, applicability, and performance of building insulation systems.

Abstract

Aims: This study aims to analyze experimental approaches used to evaluate the thermal insulation performance of bio-based wall materials derived from agro-industrial waste, with a specific focus on Palm Oil Fuel Ash (POFA) and eggshell powder, in the context of sustainable tropical building applications. Methodology and results: This study employed a Systematic Literature Review (SLR) consisting of three primary stages: a comprehensive search across reputable databases (Scopus, ScienceDirect, and Google Scholar), article selection based on predefined inclusion criteria, and thematic analysis of 78 eligible studies. The review focused on experimental methods for evaluating thermal performance, including thermal conductivity (Hot Disk, Guarded Hot Plate), specific heat capacity (DSC), surface reflectance (UV-VIS), and chemical-microstructural analyses (TGA, SEM-EDS, XRD). Findings indicate that POFA and eggshell powder exhibit thermal conductivity values between 0.12–0.25 W/m·K, attributed to microporous structures and high SiO₂ or CaCO₃ content. Nonetheless, the integration of these laboratory findings with building energy simulations and the consideration of tropical, specific variables, such as humidity and solar radiation, remains notably limited in existing literature. Conclusion, significance and impact study: This study identifies critical methodological gaps in current research on bio-based thermal insulation materials and underscores the need for a more integrated evaluation framework. Specifically, it recommends combining laboratory testing with building energy simulation to enhance the validity and applicability of findings. Such an approach is essential for advancing the reliable implementation of agro-industrial bio-waste materials, such as POFA and  eggshell powder, in sustainable tropical architecture. The proposed integration not only strengthens the scientific foundation of material performance assessment but also contributes to more climate-responsive and low-carbon building design strategies in the Global South.

Abstract

Ensuring fire safety in dense residential areas is a major concern in urban disaster mitigation. The high incidence of fires and their impacts, including fatalities, economic losses, and social disruption, underscore the need to evaluate existing prevention systems. Aims: This study examines the relationship between fire alarm availability, evacuation training participation, and community preferences for improving fire safety measures. Methodology and results: A mixed-methods approach was used, integrating quantitative chi-square analysis with qualitative grounded theory. Quantitative data were obtained from a structured survey of 111-respondents, and qualitative data were derived from open-ended responses analyzed through open, axial, and selective coding. The results revealed a significant association between fire alarm availability and preferences for strengthening early warning systems (p = 0.0025). Participation in evacuation training was also significantly related to recommendations for improving evacuation facilities and procedures (p = 0.0064). Qualitative findings show that trained individuals prioritize accessible evacuation routes and routine simulation exercises. Conclusion, significance, and impact study: The study proposes three strategies: (1) improving affordability and access to fire alarm systems, (2) increasing community-based evacuation training, and (3) designing evacuation routes adapted to dense settlement conditions. These measures are expected to enhance fire safety and strengthen community resilience in high-risk residential areas.
