Summary For passive building applications, phase change materials (PCMs) are microencapsulated to avoid leakage of PCM from concrete structure. The primary challenge of using microencapsulated PCM (MPCM) is its weak shell structure. New MPCMs with different shell compositions to prevent breakage during mixing in fresh concrete are needed. In this study, free radical polymerization method to microencapsulate capric acid–myristic acid mixture as PCM with two different methyl methacrylate co‐polymers is proposed to produce robust MPCMs for building applications. Two new microcapsules (MPCM‐1 and MPCM‐2) having latent heats of 91.9 and 97.3 J/g were synthesized. SEM analyses showed the size of microcapsules being in the range of 400–850 nm for MPCM‐1 and 250–475 nm for MPCM‐2. Analyses also reveal that the shells of MPCMs were not harmed, as they were added into concrete mixes. The microsphere's geometry was preserved, and distribution was homogeneous. The MPCMs were also studied under thermal tests of 1000 heating/cooling cycles. No significant changes in thermal properties were observed after thermal cycling tests.

“…Even though some studies [95,101] investigate a partition under real weather conditions, the real effect on thermal comfort and energy savings within a typical construction fully realizable. Control systems for cooling/heating play an important role in energy management and are complimentary to PCM applications; this was recommended by Berardi and Soudian [72] and implemented by Favier et al [85].…”

“…Trombe wall systems can also be added to renovations, and suitable PCM integration and control systems can enhance their performance. Favier et al [85] prepared an automatic control system for a Trombe wall equipped with PCM located in a renovation located in Croisilles, France. The study was focused on diminishing the disadvantages behind such systems that are summarized to be: unpredictable heat transfer, night heat losses, and the thermosiphon phenomenon.…”

The use of phase change material (PCM) as a thermal energy storage system integrated in new buildings, and as retrofits in old buildings, proved its merit as promising renewable energy source. Heating and cooling building applications of PCM have been studied by plenty of scientists, globally, on the basis of numerical and experimental analysis. The performed experiments have mainly focused on one application—active or passive—using permanent prototype design for a certain duration and weather condition. The current study is a new review that focuses on two complementary aspects: (1) Reviewing latest studies in PCM domain and assessing the thermal performance of implemented prototypes within the conducted PCM experimental studies, namely, the effect of the design on the number of acceptable variables and possible PCM applications; and (2) suggesting a new, advanced, flexible, and modular prototype designed to enable several applications of PCM to be adapted and combined within the model. It was implied that the new design allows different configurations that are lacking in the literature and serves for future PCM building applications of thermal analysis towards PCM integration optimization, as an attempt for transforming residential compartments into net zero energy buildings. The designed prototype overcomes the deficiencies found in previous reviewed experimental facilities.

Solar energy utilization for covering the heating loads of buildings is an innovative and clean way to reduce electricity consumption. A Trombe wall is a classical passive solar heating system used in buildings. Increasing the weights and volumes of Trombe walls can increase their heat storage capacities. However, this process increases a building's dead load, which is considered a problem by structural engineers. Among the alternatives for solving this problem is to use phase change materials (PCMs) for higher heat storage. This work presents a comprehensive review on the different advantages of integrating PCMs with Trombe walls. The article shows that the satisfactory heat storage capacity of PCMs can improve indoor air thermal circulation and decrease indoor air temperature fluctuations. In addition, the effectiveness of PCMs in providing protection from overheating, and improving the efficiency of the energy management process and energy saving of Trombe walls is demonstrated.
