“…Nano-PCM increases the thermal efficiency of the building and decrease energy consumption. According to the European Union (EU), buildings are responsible for 36% carbon emissions and 43% energy consumption (Beltrán and Martínez-Gómez, 2019). PCM layers were placed on the interior surface of the wall room facing a large window of the test room and were tested in different indoor and simulated outdoor conditions (Guarino et al, 2014).…”

The study focuses on utilization of the solar insulation in buildings by means of thermal storage materials. During months of April to October, a significant part of solar gain was noticed in outer walls as well as in roof of the structure. Light weight modern construction materials have low thermal inertia so it stores less energy. The study focuses on the utilization of Phase Change Materials (PCM) for harnessing solar thermal energy for heating buildings. Various researches that show the effect of implementing PCMs in different parts of buildings like in walls, roof, windows, doors, floor etc. has been shown in the paper. The PCMs are helpful especially for those buildings which are located in cold climatic condition. Effective solutions are still required for harnessing maximum possible solar energy for heating buildings by storing heat energy by means of thermal storage materials like PCMs in hot days and to liberate it in cold night.

“…Jayalath et al (2016) studied the effectiveness of phase change material roof layers on thermal performance of a residential building, it was found that 39% and 25% of cooling energy savings achieved in Melbourne and Sydney respectively. In recent studies, Beltra´n et al (2019) focused their studies on the selection of PCM for building wallboards and roofs based on multi-criteria decision methods. Yasin et al (2019) implemented and validated a new room model for chilled PCM ceiling into existed type in TRNSYS.…”

Phase change materials (PCMs) show a good capability in absorbing massive heat when undergoing phase change, which have great potential to be incorporated into building envelopes to enhance indoor thermal comfort by preventing heat penetration into buildings and reducing energy requirements. In this work, a deep analysis of PCM enhanced-walls model has been conducted in six representative climate regions of Morocco: El Jadida, Fez, Marrakesh, Ifrane, and Errachidia. More in detail, numerical simulations were carried out to assess the thermal behavior and energy performance of a residential building integrated with four different PCMs. The results showed that the effectiveness and selection of PCMs strongly depend on local weather where they are applied, characteristics of HVAC systems, PCM layer thickness, and position. Furthermore, with reference to each climate zone, the appropriate PCM leading to the lowest annual energy consumption was identified. The findings show that PCMs are particularly suitable for Mediterranean climates, which a promising annual energy saving of about 41% was obtained. While, the lowest value was recorded in Errachidia city reveals that the integration of PCM has little effect in desert climate zone. As for the other climates considered, values of about 28% to 31% were achieved in the studied house model.

“…The building materials majorly include bricks, cement (which is itself a mixture composed of a wide variety of materials), sand, etc., providing various options where the PCM thermal composite can be applied. In recent decades, the PCMbased building wallboards were developed [37], involving the incorporation of PCM with the gypsum, concrete, or cement [38] and other construction materials [39]. For example, Lu et al, [40] introduced form-stabilized PCM composite (70 wt.% of paraffin wax with a melting temperature of~16 to 22 • C, 5 wt.% of high-density polyethylene and 15 wt.% of expanded graphite) in the room wall and evaluated the thermal performance, finding the effective results with the composite PCM-wall.…”

Due to the tremendous increase in the population and emerging energy crisis, the surging demand for the thermal management of buildings has become essential. Thermal management of buildings is of high importance for maintaining optimum thermal comfort and controlling the drastic environmental impacts. To avoid high energy consumption strategies and continuous operation such as active air heaters and air conditioners, passive strategies driven by phase change material-based thermal storage are expected to leverage the energy challenges. This work attempts to present the form-stabilized thermal storage tile-bricks (TSTBs) that are fabricated by a combination of octadecane, phosphogypsum, kaolin clay and cement. The optimal percent contents of each entity were found with respect to the design criterion of form-stability and effective temperature control capacity. Two TSTBs with a thickness of 10 mm and 15 mm were constructed, which are then applied on ordinary clay bricks to build a prototype wall. The optimal TSTBs are experimentally and numerically evaluated by subjecting them to transient thermal performance analysis, providing longer temperature retardation (~3000 s) compared with ordinary clay bricks (~400 s). It is thus implied that TSTBs can provide a viable solution against energy mismanagement by inhibiting the heating in summer and reserving the cold in winter.
