“…The assessed models represent those six Cases designed and developed based on the previous studies' data presented in [41,42] (Table 1). The six Cases were designed considering several variables, which have been identified based on the observations during the site visits, conducted by the authorities, and investigating the local planning and design systems in the north of Iraq.…”

“…The analysis started by assessing the six designed cases (Cases 2, 3, 4, 5, 6 and 7) established in a previous study [42] through eight different cardinal (S, W, N, E) and ordinal (SW, NW, NE, SE) directions to identify the best orientation and be adopted for the further step of the study (incremental phases). Afterward, regarding construction techniques, materials, and prototype parameters, scenario nine (C1S9) techniques from [41,42] have been selected for this study for affordability and adaptability reasons. Other identified parameters are shown in Table 2.…”

“…Whereas there is a gap and limitation in the literature concerning integrating all those factors, especially regarding the context of this study. Therefore, the main contribution and real novelty of this study are to fill that gap by integrating the above factors in the six refugees' core shelters prototypes which have been designed based on the Middle Eastern cultural context using locally available sustainable construction materials and techniques established in [41,42] and to be embedded in the local planning system their three incremental phases. Subsequently, the main aim of this study is to empirically evaluate the energy and indoor environment performance of the six refugees' core shelters typologies through three incremental phases with two different positions, i.e., terraced (T) and end-of-terraced (ET).…”

Globally, natural and man-made disasters continue to force the displacement of masses of people. Existing studies show that several aspects have not been integrated into constructing refugee camps and shelters to achieve sustainability, such as long lifespan, indoor thermal comfort and air quality, energy efficiency, socio-cultural aspects, integration with local planning and design systems, and environmental impact. This study integrates the above factors in six refugee core shelters, designed based on the Middle Eastern cultural context using locally available sustainable construction materials and techniques. The prototypes are situated on two different building plots, i.e., terraced and end-of-terrace, and undergo three development phases, known as the incremental improvement strategy. The study focuses on their energy and indoor environment performance and provides empirical assessments undertaken using dynamic building simulations. It shows that the adopted approach to design and construction leads to remarkable improvements in their overall performance. Concerning energy use, compared to the base case scenarios built with conventional materials, the proposed prototypes show an opportunity to save energy up to 10,000 kWh per unit per year, equivalent to almost 2500 USD savings in energy bills. This is while achieving accepted level for almost 89–94% of thermal comfort hours and 74–85% predicted mean vote (PMV), respectively. However, the CO2 concentration level remains relatively low, ranging from 29 to 51%.

“…Global energy consumption is predicted to jump in the upcoming decades due to the rapid growth in population and urbanization [1]. Presently, 80% of the energy consumption is supplied by fossil fuels which have harmful environmental implications like CO 2 emission, global warming, and climate change [2,3]. Buildings are indeed the highest energy consumer, accounting for around 40% of the overall global energy usage.…”

This study evaluated the possibility of producing innovative glass-ceramic foams from zeolite-poor rock (Tokaj, Hungary) using alkali-activation and reactive sintering techniques. The composition and morphology of the samples were studied using X-ray diffraction, X-ray fluorescence, scanning electron microscope, and computed tomography techniques. The influence of various sintering temperatures on glass-ceramic foams was examined. It has been observed that zeolite-poor rock has a self-foaming capability. The heat treatment temperature affects the pore size and distribution as well as the technical characteristics of the obtained samples. The resulting glass-ceramic foams possess moderate thermal conductivity ranging from 0.11 to 0.17 W mK−1 and good compressive strength (1.5–4.4 MPa). The produced samples might be utilized for thermal insulation, which would have both economic and environmental advantages.

The number of migrants increases globally due to natural disasters, global warming, and war conflicts. Inefficient and unsustainable construction approaches for migrant shelters have resulted from improper planning and design systems regarding lifespan, materials and techniques, and socio-cultural aspects. Therefore, the study aim has an incentive to assess the impact of the morphological, siting, and layout of zones and shelters for the long-term displacement prototypes considering sustainability concepts from social context, affordability, adaptability, low-impact construction materials, and techniques. Furthermore, applying the dynamic simulation IDA ICE 4.8 tool was cardinal to justify the comprehensive reported outcomes based on the bottom-up construction method after assessing energy and thermal comfort performance in seven cases. The energy performance assessment regarding heating reveals the superiority of the compact layout plan system, while the open-layout plan system is superior for electric cooling assessment. Concerning thermal comfort performance for the number of accepted hours category, the open-layout plan system is superior. Fanger indicators for thermal comfort assessment demonstrated the superiority of the horizontal-compact layout plan scheme. The carbon dioxide (CO2) concentration level assessment shows that the open-yard layout cases have better results than other systems. To conclude, sustainable prototypes for displaced people should involve several aspects such as lifespan, socio-cultural and affordability, thermal performance and energy-efficient, and environmental impact. The beneficiaries from the methods and the results of this study would be firstly the Syrian refugees in the Middle East context, then various places and involved people affected by the displacement issue globally.
