Maintaining building indoor temperature within comfort zone has been identified as one of the major reasons for energy consumption. The incorporation phase change materials (PCMs) in various regions buildings is introduced a solution that can significantly reduce In current research, three-dimensional computational fluid dynamics approach taken to evaluate influence incorporating three PCMs from Rubitherm® RT line (RT15, RT18, and RT22) two widespread commercial hollow brick types Iran keeping environment shelter warm cold climate. These enhanced bricks are compared with their solid counterparts. Furthermore, efforts were made examine configurations these PCMs, melting temperatures obedience or contrast thermal stratification bricks. Several combinations PCM air layers studied assess best way place layers. It was found RT18 PCM-filled present lower heat fluxes than over 42 h. Also, findings showed RT22 provide 66.79% average flux first 24 h process.

When it comes to guaranteeing appropriate performance for buildings in terms of energy efficiency, the building envelope is a crucial component that must be presented. substance goes through phase transition and either gives out or absorbs an amount provide useful heat cooling, called phase-change material, PCM short. Transitions often take place between matter’s solid liquid states. Buildings use PCMs variety purposes, including thermal comfort, conservation, managing temperature materials, reducing cooling/heating loads, load shifting. Improved solutions are applied using new method approach investigations. Undoubtedly, researching applying applications can help create more energy-efficient environmentally friendly, while also increasing comfort consuming less energy. It provides possible answer problems posed by climate change, rising demand built environment, optimisation. However, true no particular research has yet been conducted thoroughly analyse linked industry. Thus, principal tactics addressed this paper determine current efficient methods employing store By gathering around 50 instances from open literature, study conducts thorough assessment up-to-date studies 2016 2023 used as storage applications. As result, review aims critically evaluate integration storage, identify number issues require research, draw some important conclusions body literature. Specifically, roof external wall uses highlighted research. Applications, general desired characteristics, types their behaviour described.

Thermal energy storage in building envelopes is critical to promoting renewable energy, implementation of which requires thermal performance enhancement construction materials. In this regard, phase change materials (PCMs) are often incorporated with cement-based composites (CBCs) materials, most commonly used construction. The current article provides a state-of-the-art review PCM-incorporated CBCs (PCM-CBCs) considering various CBCs, incorporation methods, and their challenges solutions. Additionally, evaluation PCM-CBCs carried out based on thermal, mechanical, durability, sustainability, efficiency, resource conservation-based performances. It was identified that terms performance, natural conservation, the research has been well established, they find vast application TES management systems. On other hand, although healthy data available appraisal mechanical PCM-CBCs, more efforts required control detrimental impact PCM make them durable desirable for where must undergo loading. This consolidated perspective researchers, practitioners, educators working practical.
