The global construction industry significantly contributes to energy consumption and greenhouse gas emissions, necessitating immediate action for sustainable development. Recognizing the impact of buildings on emissions, the United Nations has set ambitious energy-related goals for 2030. Retrofitting buildings emerges as a strategic method for reducing energy consumption, offering lower environmental impact and life cycle costs. However, retrofitting is a complex process influenced by diverse factors such as policies, available resources, techniques, building-specific data, and uncertainties. Thus, this paper reviews the existing literature on retrofitting strategies for tropical and humid climates to identify effective approaches for enhancing energy efficiency, thermal comfort, and overall building performance in these regions. Through comprehensive analyses, including bibliometric analysis using VOSviewer version 1.6.18 and systematic assessments, this study investigates various retrofitting strategies. This study categorizes tropical climates into Af (Tropical Rainforest Climate) and Aw (Tropical Savanna Climate) based on the Köppen climate classification. It reveals distinct emphases, with Af climates concentrating on office buildings and Aw climates prioritizing residential structures. Passive strategies were predominantly favored in office buildings, with glazing being the most commonly implemented approach. Residential structures, on the other hand, adopted a combination of passive strategies such as phase change materials along with active methods like appliance replacement. Educational buildings tended to rely on passive strategies, including roof covers, shading, and glazing. The absence of specific cost values underscores the importance of establishing baseline metrics, revealing significant challenges in retrofit techniques. This study further highlights an opportunity to explore passive methods in educational buildings, stressing the need for comprehensive guidelines, especially in institutional settings. Moreover, it emphasizes the urgency for ambitious regulations to address carbon emissions and optimize energy efficiency in tropical climates.

“…This action resulted in a 27% cost savings. LCC was also studied in the investigation by M.J. Abden [61], and the option selected (a combination of EPS and FSPCM) had the highest cost. Nevertheless, the payback period was appropriate (2.2 years), which is why, under this consideration, this option was chosen.…”

“…This involves selecting and installing materials that effectively resist heat transfer, minimizing the exchange of heat between the interior and exterior environments. By incorporating these high-quality components, a structure can better retain or repel heat, resulting in improved energy conservation and a more comfortable indoor environment [29]- [31].…”

Various green building rating systems have been devised to assess the sustainability levels of buildings, offering a standardized approach to evaluate their environmental impact. However, adapting these existing methods to diverse regions requires addressing additional considerations, such as distinct climatic conditions and regional variations. This study delves into a comprehensive exploration of widely utilized environmental building assessment methodologies, including BREEAM, LEED, SB-Tool, CASBEE, GRIHA, and Eco-housing. A new building environmental assessment scheme tailored to the global landscape is needed due to limitations of existing assessment schemes. A framework based on principal component analysis is introduced to develop this new scheme. PCA applied to a dataset of many responses on building sustainability revealed nine key components, including site selection, environmental impact, building resources and re-use, building services and management, innovative construction techniques, environmental health and safety, mechanical systems, indoor air quality, and economic considerations. A framework for sustainable building development in world is proposed. The study provides insights for designers and developers in developing countries, offering a roadmap for achieving green development. The framework prioritizes key components for a nuanced evaluation of sustainability in building projects, contributing to the global discourse on environmentally responsible construction practices.

“…Concerns about the question of climate change and sustainable development have steadily increased in the international community, especially in the field of construction. Thus, the issue today is to respond urgently, while thinking about the future, to these two challenges of the 21st century, to limit greenhouse gas emissions (Kurekci, 2016;Islam and Bhat, 2019;Ozturk et al, 2019;Santamouris et al, 2020;Abden et al, 2022;Wang et al, 2022). It is therefore mandatory to look for renewable energy sources able to replace coal and oil, especially in buildings that consume about 30-40% of the world's energy to ensure a healthy and comfortable space.…”

The impact of PEG bulk volume fraction on the interlayer distance of clay- PEG hybrids: Experimental and theoretical study

The intercalation of polyethylene glycol (PEG) chains, in the inter-layer environment of the clay from Meknes, was performed using the direct intercalation method in the presence of water as a solvent. X-ray diffraction (XRD) technique was applied to follow the evolution of interlayer distances as a function of PEG bulk volume fraction. The XRD data assert the formation of an intercalated structure through the displacement of the peaks, which characterize the clay minerals towards the small and large angles. The evolution of the d001-spacing for the three classes of clays was similar. Indeed, as φ increases, the d001 variation is marked by two depletion phenomena due to the magnitude of the gyration radius compared to the inter-layer distance of the clay minerals. The plateau regime, characterized by the weak insertion of the chains, appears after each depletion/expansion cycle, which reveals a succession of the depletion-adsorption-plateau phenomenon. Based on the results of the XRD method, we proposed a model for the insertion of PEG chains in monolayer and bilayer forms into the interlayer environment of clay minerals. Finally, the scaling theory reveals a good agreement with the experimental findings and perfectly illustrates the succession of three regimes: dilute, bidimensional semi-dilute, and plateau.
