“…Phase change materials (PCM) present the ability to store more heat per unit volume due to their latent heat thermal storage [1][2][3][4]. Thus, both the indoor thermal environment and energy use of buildings can benefit from PCMs because of their specific temperature range, peak-shaving and load shifting ability [1,4].…”

Two commercially available ceiling panels, one metal and one gypsum incorporating microencapsulated PCM were compared experimentally to determine their limitations and ability to provide an adequate indoor thermal environment. The experiments took place from February to May 2018 in a climate chamber at the Technical university of Denmark. In total, seven scenarios were evaluated, five with active cooling, where the flow rate and solar heat gains were varied, and two without. Results showed that according to EN 15251:2007, the RCPs maintained the best indoor thermal environment for 91% of occupancy time in Category III – operative temperature between 22oC and 27oC, and 75% in Category II – operative temperature between 23oC and 26oC, for a 140 kg/h flow rate and the reference solar heat gains. Alternatively, the PCM panels maintained Category III for only 48% of the time, while only 30% in Category II for a 220 kg/h flow rate and the reference solar heat gains. The PCM panel presented the ability to store the heat for a later time. However, the PCM panels’ solution proved inadequate in terms of heat storage capacity, pipe positioning and thermal conductivity while improvements are required in order to employ them in new and renovated buildings.

“…The melting temperature of the microencapsulated PCM used in this study was also measured as 25.5 °C in accordance with the values given in Table . Another study offers to use PCM technology in the climates where the indoor temperature is mainly in the range of PCM transition temperature. For the climates where the indoor temperature mainly goes beyond the PCM functional temperature, the application of supplementary energy efficient techniques such as night ventilation was suggested .…”

The use of solar energy has become a promising method to reach energy efficient solutions throughout the last century. Improving the thermal properties of building members will contribute to the efficient use of energy by preventing heat gain/loss through the building envelope. Phase change materials (PCMs) are favorable materials for thermal applications because of their large contribution to the thermal mass of a building and thus providing “inertia” against temperature fluctuations. In this experimental study, glass fiber‐reinforced cementitious composites were modified using a commercial microencapsulated PCM to improve their thermal performance. The thermal and the mechanical performances of the composites were investigated. With the use of PCMs, the latent heat capacity of the composites increased while the thermal conductivity decreased. Conversely, the mechanical properties of composites declined with increases in PCM amount. The main conclusions of the experimental study are as follows: PCMs provide a great potential to fiber‐reinforced cementitious composites to support the efficient use of energy, thereby enhancing the thermal features of the composites. The performance of PCM composites shows a serious variation according to different service temperatures. Therefore, the effect of service temperature must be considered particularly with respect to safe utilization of these materials. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13061, 2019

“…Phase Change Materials (PCM) have high thermal capacity per unit volume compared to sensible heat storage materials such as brick and concrete, that have traditionally been applied in buildings, and work by raising the temperature of the materials. PCM on the other hand have both sensible heat storage capacity and significant amount of energy is exchanged during change of state of the materials [11].…”

“…PCM application has also been investigate under hot climatic conditions. Derraji et al [14] evaluated the application of PCM wall system for improving thermal comfort conditions in buildings under the hot climate of Algeria using Transient System Simulation Software (TRNSYS) and concluded that there is significant improvement in indoor condition in summer and winter. Solgi et al [15] also investigated the potential of using PCM and nigh ventilation for reducing cooling load in office buildings in hot Arid climate of Yazd, Iran.…”

Indoor Environmental Quality (IEQ) is essential for the health and productivity of building users. The risk of overheating in buildings is increasing due to increased density of occupancy of people and heat emitting equipment, increase in ambient temperature due to manifestation of climate change or changes in urban micro-climate. One of the solutions to building overheating is to inject some exposed thermal mass into the interior of the building. There are many different types of thermal storage materials which typically includes sensible heat storage materials such as concrete, bricks, rocks etc. It is very difficult to increase the thermal mass of existing buildings using these sensible heat storage materials. Alternative to these, there are latent heat storage materials called Phase Change Materials (PCM), which have high thermal storage capacity per unit volume of materials making them easy to implement within retrofit project. The use of Passive Cooling Thermal Energy Storage (TES) systems in the form of PCM PlusICE Solutions has been investigated in occupied spaces to improve indoor environmental quality. The work has been carried out using experimental set-up in existing spaces and monitored through the summer the months. The rooms have been monitored using wireless temperature and humidity sensors. There appears to be significant improvement in indoor temperature of up to 5°K in the room with the PCM compared to the monitored control spaces. The success of PCM for passive cooling is strongly dependent on the ventilation strategy employed in the spaces. The use of night time cooling to purge the stored thermal energy is essential for improved efficacy of the systems to reduce overheating in the spaces. The investigation is carried within the EU funded RESEEPEE project.
