“…The monthly recuperation heat flux densities for P24 in Prague ranged from 4.9 to 5.6 kWh•m −2 . However, the improvements were significantly lower compared to Liu et al [51] due to increased thermal conductivity of the ceramic brick allowing more significant heat transmission from the plaster to the load-bearing structure. Therefore, the interior surface performance was significantly worsened thus, the detected improvements ranged between 8.61%-13.2% during particular months (P24, Prague).…”

Facing the consequences of climate change and fuel price rises, the achievement of the requirements for low-energy consumption of buildings has become a challenging issue. On top of that, increased demands on indoor hygrothermal conditions usually require the utilization of additional heating, ventilation, and air-conditioning (HVAC) systems to maintain a comfortable environment. On this account, several advanced and modern materials are widely investigated as a promising way for reduction of the buildings’ energy consumption including utilization of passive heating/cooling energy. However, the efficiency and suitability of passive strategies depending on several aspects including the influence of location, exterior climatic conditions, load-bearing materials used, and insulation materials applied. The main objective of this study consists of the investigation of the energy performance benefits gained by the utilization of advanced materials in plasters by computational modeling. Results obtained from a computational simulation reveal the capability of the studied passive cooling/heating methods on the moderation of indoor air quality together with the reduction of the diurnal temperature fluctuation. Achieved results disclose differences in terms of energy savings for even small variation in outdoor climate conditions. Additionally, the effectivity of passive cooling/heating alters considerably during the summer and winter periods. Based on the analysis of simulated heat fluxes, the potential energy savings related to improved thermal properties of the applied plaster layer reached up to 12.08% and thus represent an interesting passive solution towards energy sustainability to meet the criteria on modern buildings.

“…Moreover, the free-floating experiments demonstrated that the use of HVAC system is almost not necessary during the mild winter period. Liu et al [119] investigated the thermal performance of a non-ventilated multilayer glazing facade filled with phase change material. The study included the installation of three test facilities as shown in Figure 12, and a model was prepared to obtain valuable results for direct analysis.…”

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

“…Compared with traditional sensible-heat-based materials, latent-heat-based phase change materials (PCMs), i.e., para n wax, n-octadecane, and tetracosane, have higher heat storage e ciency during the melting process, lower volume occupation, and relatively stable melting temperature; thus, they o er great potential in developing low-carbon buildings for e cient thermal management [1][2][3][4]. Currently, the PCMs have been integrated with the concrete wall components [5] and glazing units [6,7] to investigate their capability in passively regulating room temperature.…”

Phase change material (PCM) is particularly advantageous in developing low-carbon buildings. However, its melting efficiency is severely determined by the dynamics of the molten phase, which is greatly associated with the applied heating orientation. This work aims to describe the dynamic character in the melting process of paraffin under different heating modes. A total of four heating modes are considered for the paraffin enclosed in a square cavity, including side heating, top heating, bottom heating, and around heating. The around heating can be regarded as the combination of the first three heating modes along a single wall. A comparative study of numerical and experimental results of temperature is firstly performed for the side heating case to verify the computational model, which is then extended to study the dynamic state during the melting process of paraffin. The evolutions of the solid/liquid interface and the internal flow field show that the bottom heating can maximally activate the involvement of natural convection of the liquid paraffin and thus has the highest efficiency than the side and top heating. The contribution rate of the bottom heating is about 1.55 times over that of the top heating. This observation is useful to identify the contribution of each heating mode to the heat transfer in the paraffin and guide its practical application.
