“…Hang Yu et al [97] investigated the fabrication of diatomite-based form-stable composite PCM wallboard for external building walls. Sayilacksha Gnanachelvam et al [98] studied the utilization of tree wallboards (gypsum plasterboard, fiber cement board, and magnesium sulphate board) and a bio-PCM mat as fire resistant wallboards for their application to light-gauge steel-framed (LSF) wall systems made of cold-formed steel studs. Gypsum plasterboards provide better fire resistance that the other wallboards, and fiber cement boards provided the lowest.…”

The management of energy consumption in the building sector is of crucial concern for modern societies. Fossil fuels’ reduced availability, along with the environmental implications they cause, emphasize the necessity for the development of new technologies using renewable energy resources. Taking into account the growing resource shortages, as well as the ongoing deterioration of the environment, the building energy performance improvement using phase change materials (PCMs) is considered as a solution that could balance the energy supply together with the corresponding demand. Thermal energy storage systems with PCMs have been investigated for several building applications as they constitute a promising and sustainable method for reduction of fuel and electrical energy consumption, while maintaining a comfortable environment in the building envelope. These compounds can be incorporated into building construction materials and provide passive thermal sufficiency, or they can be used in heating, ventilation, and air conditioning systems, domestic hot water applications, etc. This study presents the principles of latent heat thermal energy storage systems with PCMs. Furthermore, the materials that can be used as PCMs, together with the most effective methods for improving their thermal performance, as well as various passive applications in the building sector, are also highlighted. Finally, special attention is given to the encapsulated PCMs that are composed of the core material, which is the PCM, and the shell material, which can be inorganic or organic, and their utilization inside constructional materials.

“…Recently, the effect of a new plaster composite containing a nano-encapsulated PCM was studied experimentally. 20 Fabrication of a novel NPCM is done by representing the capsules into thermal performance and mechanical properties. It is observed from the literature that after adding CuO nanoparticles, NPCMs paraffin leakage rate is significantly decreased.…”

Influence of phase change material encapsulation shape on performance of energy‐efficient roof design

et al. 2022

The design of passive cooling systems is part of the energy-efficient building since population growth and indoor requirements in various dwellings are paramount. As a part of passive designs, modifying the conventional roof with phase change materials (PCM) is one of the techniques to control the abnormal changes of the inner surface temperature of the roof. In this aspect, a numerical investigation has been carried out by incorporating the PCM encapsulated pipes in the RCC (reinforced concrete), and a comprehensive analysis has been carried out. Three different shapes are chosen, namely circular, oval, and rectangular oval, to encapsulate the PCM. Diurnal outside changes are considered to envisage the inner surface temperature of the roof. Validation of the literature's experimental results is done before developing a numerical model for the current study. The effect of encapsulated shape on PCM's average temperature, liquid fraction and energy storage has been studied. The inner surface temperature is reduced drastically with the roof consisting of elliptical encapsulated PCM than other designs such as circular and rectangular oval encapsulated PCM. Moreover, the performance of PCM is sensitive to encapsulated shape and location within the system.

“…This could be performed both on the interior and on the exterior sides, to reduce the consumption for heating or for cooling. This type of application has gained increasing attention and several researchers have focused on it during the last decade [5,10,[17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”

The construction sector is among the major players responsible for global energy consumption and therefore related emissions, both because of the constantly increasing indoor air quality standard which requires increasingly higher energy demands as well as the great share of historical buildings which are now obsolete and are not up to date with current regulations. Phase change materials (PCMs) applied on the building envelope represent a feasible possibility to improve the performance of existing buildings, also the historical ones, increasing their thermal inertia without violating any legal restriction or causing further alterations to the structure. More specifically, focus of this research was on the addition of a granular paraffin PCM into a lime-based plaster. Experimental tests at lab scale and numerical simulations with COMSOL Multiphysics were carried out to characterize the plasters realized, namely one reference lime-based plaster and one with incorporated 10% by mass of granular PCM (named REFp and PCMp, respectively). The behavior of these plasters applied on the exterior side of a wall was then simulated and compared in terms of temperatures and heat fluxes. However, considering that the estimated thermal conductivity of the reference lime-based plaster was lower than the values found in literature, the simulations were carried out considering an additional plaster, namely a lime-based plaster (renamed LITp), whose properties were found in literature and considered quite representative of a consistent share of existing historical buildings. Great improvements were observed from the application of PCM into the plaster, with reductions of the incoming energy between 9% and 18%.
