“…Chiara Molinari et al, assessed the thermal performance of soda lime glass scraps and PCM-impregnated tiles. In the range of 0.6 to about 1.2 g/cm 3 , the specimens before impregnation possessed higher thermal conductivity and that after impregnation possessed lower thermal conductivity; and in the range of about 1.2 to 1.4 g/cm 3 , the specimens before impregnation possessed lower TC and that after impregnation possessed higher thermal conductivity [68]. Hyun Koo et al [69] investigated the effects of buffer layers on thermochromic properties of soda lime glass.…”

The thrust to find new technology and materials has been greatly increasing due to environmental and technological challenges in the progressive world. Among new standard materials and advanced nano-materials that possess a huge potential and superior thermal, mechanical, optical, and magnetic properties, which have made them excellent and suitable components for mechanical engineering applications. The current review paper deals with recent enhancements and advances in the properties of nano-structured glasses and composites in terms of thermal and mechanical properties. A fabrication method of nano-structured glass has briefly been discussed and the phase change material (PCM) method outlined. The comprehensive review of thermal and optical properties confirms that nano-fabricated glasses show both direct and indirect running of band gaps depending on selective nano-structuring samples. The electrical and magnetic properties also show enhancement in electrical conductivity on nano-structured glasses compared to their standard counterparts. The realistic changes in thermal and mechanical properties of nano-structured glasses and composites are commonly attributed to many micro- and nano-structural distribution features like grain size, shape, pores, other flaws and defects, surface condition, impurity level, stress, duration of temperature effect on the selective samples. Literature reports that nano-structuring materials lead to enhanced phonon boundary scattering which reduces thermal conductivity and energy consumption.

Solar desalination systems are effective and sustainable applications that are utilized to obtain potable water from saline or contaminated water. In this research, three solar desalination systems, including a conventional system, a phase change material (PCM)-based thermal energy storage unit (TESU), and a natural dolomite powder integrated PCM-based TESU, were structured and experimentally investigated. The developed solar desalination systems were analyzed simultaneously and the findings were discussed in detail. According to the empirically obtained outcomes, utilizing PCM-based TESUs and dolomite-powder-embedded PCM-based TESUs increased daily cumulative productivity by 10.15% and 17.70%, respectively, in comparison to the conventional distiller. Employing dolomite powder increased the energy and exergy efficiencies of the conventional distiller from 15.91% to 18.28% and from 1.26% to 1.78%, respectively. Moreover, environmental metrics such as global warming potential and the sustainability index of the developed solar desalination systems were analyzed within the scope of this work.

“…To choose the proper phase change material, you must first determine the wall composition, exterior building walls orientation, PCM layer location in the wall, and the time of year during which the PCM is expected to lower the building's thermal load. These variables will influence the PCM selection as described in many articles [18,21,25,29]. But the most critical parameter that affects the PCM selection is the building's location where the solar irradiance change according to changing the altitude of the country.…”

“…Another numerical research is performed using EnergyPlus to evaluate the impact of integrating a PCM layer in a traditional building envelope for eight different cities. Thirteen different PCMs with melting temperatures ranging from 20 to 32 °C were studied, and the results show that For Abu-Dhabi, Dubai, Faisalabad, Mecca, Nouakchott, Jodhpur, Cairo, and Biskra, the best thermal performance was found when a PCM with a melting point at 27,27,29,27,31,32,20, and 21 °C, respectively [37]. Another study investigated the impact of PCM on energy savings.…”

Integrating a phase change material (PCM) into building envelopes can reduce energy needs in the built environment, and the consequent greenhouse emissions. This research examines the impact of PCM integrated into a traditional wall in Egypt on peak and average cooling energy consumption. A MATLAB code based on the finite volume technique using the Crank-Nicolson method for discretization is implemented. Several benchmark cases and experimental results validate the code. The time-dependent boundary conditions of the cases examined were based on the irradiance and ambient temperatures measured in Cairo, Egypt. Simulations are performed on eight different PCMs, using their real published DSC curve. The study aims to investigate the performance of each PCM at different positions, thicknesses, and wall orientations. The calculations revealed that using the proper PCM type and the proper position could decrease the average by 38.14%, Also the peak heat flux could be decreased by 58.53%.
