Researchers worldwide are investigating thermal energy storage, especially phase change materials, for their substantial benefits in improving energy efficiency, sustaining thermal comfort in buildings and contributing to the reduction of environmental pollution. Residential buildings and commercial constructions, being dependent on heating and cooling systems, are subjected to the utilization of PCM technology through several applications. The current study presents a state-of-the-art review that covers recent literature on thermal energy storage systems utilizing PCMs for buildings. The reviewed applications are heating and hybrid applications, that are categorized as passive and active systems. A summary of the PCMs used, applications, thermo-physical properties and incorporation methods are presented as well. The study emphasizes the promising effectiveness of PCM in building heating applications, and highlights the significance of PCM system hybridization. The study shows that experimental investigations on commercial constructions, and hybrid systems development and optimization, are still required. Finally, possible combinations of active and passive heating applications with their auspicious benefits in terms of energy efficiency augmentation, are recommended. Highlights  State-of-the-art review on PCM building applications for heating and hybrid systems  Active and Passive classification for heating and hybrid systems  Challenges altering the PCM technology for energy-efficient buildings are addressed  Hybridization of active and passive systems forms a potential method toward NZEB

“…Solidification temperature is the temperature at which a material converts from the solid phase to the liquid phase. Based on the findings of the applications, the most suitable PCM is the one which has a solidification temperature which is the closest to the indoor temperature [4] [11].…”

“…There are many studies on PCM applications on buildings. Among those; Al-Saadi and Zhai [3], Kalnaes and Jelle [4], Kuznik [5], F. Souayfane, F. Fardoun and P. H. Biwole [6], Köse and Manioğlu [7][8] claim in their studies that PCMs optimize indoor comfort conditions and reduce energy consumption through theirs thermal storage capabilities [9][10] In addition to the above mentioned studies, in this study, heating and cooling energy consumptions when PCM is applied on external walls for a middle unit with different orientations and in different climatic regions (temperate-humid, hot-dry) were calculated using a simulation program and evaluated using comparative analyses.…”

Minimizing the effect of climatic conditions and energy consumption in buildings are important issues to be considered in the building design process. Due to the changes in climatic conditions, there is an increase not only in the consumption of heating energy but also cooling energy. Certain passive measures to be taken primarily for the building envelope are necessary in order to reduce energy consumption. Applying a phase-change material on the surface of a building envelope is one of the new approaches for controlling heat transfer through the building envelope during the cooling period. It is known that phase-change materials, which are also considered as modern versions of thermal mass concept, can reduce the of a building’s heating and cooling energy consumption. In this study, a unit with 10m to 10m dimension with one external facade in a 3 storey building was evaluated in two cities, Istanbul and Diyarbakır, in temperate-humid and hot dry climatic regions. In order to reduce heating and cooling loads, a phase-change material was applied on the surface of the building envelope. The thickness of the phase-change material on the applied surface was increased at every step, and different building envelope alternatives were created. Heating and cooling energy consumptions were calculated for different orientations of the external facade. When calculated values are evaluated comparatively, it is seen that as the thickness of the phase-change material increases, the energy loads occurred in the unit decrease gradually. Equally, the performance of the phase-change materials varies depending on the orientation. Therefore, it is possible to determine the optimum thickness and orientation combination of the phase-change material application on a building envelope and reduce heating and cooling energy consumptions.

reported the comparison results in the range of 0-10 based on the equations. The ideal case demonstrates the highest possible level of efficiency, and lifespan, specific power and energy, energy and power density, technical maturity, and the lowest possible power and energy capital cost, self-discharge rate, and environmental impact. [13] Figure 1c represents the PCMs' characteristics.In a previous review, Sadeghi (2022), discussed the thermal energy management of batteries and high-heat-flux electronic devices, and the capability of the TES systems. [2] Costa and Kenisarin (2022) produced a database of metallic PCM's thermophysical features and potential impact in diverse fields, for instance, bioengineering, electronics, solar energy storage, cooling and heating, and beyond. [8] Chavan (2022) covered the recent progress in TES and its usages such as waste heat recovery, solar-based TES, building applications, thermal comfort, heavy electronic equipment cooling, vapor absorption refrigeration (VAR), and Heating, ventilating, and air-conditioning (HVAC) applications. [14] An increasing number of recent research addresses the use of PMCs in human body, detection or sensing, biological, barcoding, drug delivery, and medical applications. However, there is no review comprehensively discussing the life science applications of TES and PMCs materials. Based on our literature survey we concluded that a review of the life science applications of PCMs is a required reference. Besides, the evaluation and safety aspects of TES will be explored in this review. Furthermore, the challenges and recommendations of PCM applications will be addressed in order to assist energy technologists and streamline future research.
