“…Samples were taken from the centre of the PCM plasterboard and found to be sufficiently homogeneous to ensure very good repeatability. In tandem with the existing TGA data of the microcapsules Fire Performance of Phase Change Material Enhanced Plasterboard [5,14] this provides a means to interpret the thermal degradation of integrated PCM plasterboard. More details on the experimental setup can be found elsewhere [15].…”

Abstract. Sustainable construction materials are increasingly being used to reduce the carbon footprint of modern buildings. These materials have the potential to change the fire dynamics of compartments by altering the compartment energy balance however there is little quantitative understanding of how these materials behave in the event of a real fire. The changes in fire dynamics may be due to increased fuel load in a compartment, reduced time to failure or promotion of flame spread. The objective of this research is to quantify how Phase Change Materials (PCMs) perform in realistic fire scenarios. It was found that a plasterboard product containing microencapsulated PCMs will behave similarly to a charring solid and have the potential to contribute significant fuel to a compartment fire but that they maintain integrity for the duration of flaming period. The critical heat flux for this product was determined in the cone calorimeter to be 17.5 ± 2.5 kW m . Sample orientation was found to increase the peak heat release rate by up to 25%, whilst having little to no effect on the mass loss rate. These parameters, in addition to the in-depth temperature evolution and ignition properties, can be used as design criteria for balancing energy savings with quantified fire performance.

“…Additionally, they are non-toxic, non-corrosive, and chemo-physically stable [4]. The weakest feature of paraffin is flammability [5] which limits the possibilities of their application in building interiors [6]. Simultaneously, the inner location of PCM layer is the most effective solution for stabilizing the indoor temperature [7,8].…”

Periodical changes of temperature on an external surface of building envelope, e.g., thermal stress or excessive heat gains, is often an undesirable phenomenon. The idea proposed and described in the following paper is to stabilize the external surface temperature in a period of significant heat gains by the originally developed, novel composite modified by phase change material (PCM) and applied as an external, thin finishing plaster layer. The PCM composite is made from porous, granulated perlite soaked with paraffin wax (T m = 25 • C) and macro-encapsulated by synthetic resin. The effect of temperature attenuation was estimated for two designated periods of timethe heat gains season (HGS) and the heat losses season (HLS). The attenuation coefficient (AC) was proposed as evaluation parameter of isothermal storage of heat gains determining the reduction of temperature fluctuations. The maximum registered temperature of an external surface for a standard insulation layer was around 20 K higher than for the case modified by PCM. The calculated values of AC were relatively constant during HGS and around two times lower for PCM case. The obtained results confirmed that the proposed modification of an external partition by equipped with additional PCM layer can be effectively used to minimize temperature variations and heat flux in the heat gains season.

“…A study by Cai et al showed that the addition of organophilic montmorillonite (OMT) nanocomposites to a form-stable paraffin contributes to flammability properties enhancement [190]. Accordingly, PCM used in buildings has to follow the fire safety guidelines, and be developed and enhanced as in many research studies [191,192] so that no restrictions ban its utility.…”

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
