“…For instance, E.Oro et al [6] and Gang Li et al [7] reviewed PCMs melting point below 20 ºC for cold thermal energy storage applications. Agyenim et al [8] identified phase change materials of melting temperature within 0-65 ℃ to be suitable for domestic heating/cooling application. They also stated that PCMs of melting temperatures 80℃ to 120℃ could be used in absorption cooling system whereas those types of melting temperatures above 150℃ could be applied in solar power plants systems coupled with parabolic trough collectors for direct steam generation.…”

Various types of solid-liquid phase change materials (PCMs) have been reviewed for thermal energy storage applications. The review has shown that organic solid-liquid PCMs have much more advantages and capabilities than inorganic PCMs but do possess low thermal conductivity and density as well as being flammable. Inorganic PCMs possess higher heat storage capacities and conductivities, cheaper and readily available as well as being non-flammable, but do experience supercooling and phase segregation problems during phase change process. The review has also shown that eutectic PCMs have unique advantage since their melting points can be adjusted. In addition, they have relatively high thermal conductivity and density but they possess low latent and specific heat capacities. Encapsulation technologies and shell materials have also been examined and limitations established. The morphology of particles was identified as a key influencing factor on the thermal and chemical stability and the mechanical strength of encapsulated PCMs. In general, in-situ polymerization method appears to offer the best technological approach in terms of encapsulation efficiency and structural integrity of core material. There is however the need for the development of enhancement methods and standardization of testing procedures for microencapsulated PCMs. Abstract: Various types of solid-liquid phase change materials (PCMs) have been reviewed for thermal energy storage applications.

“…Regarding building applications, PCMs should have a melting/solidification temperature in the practical range of application, high latent heat of fusion and improved thermal conductivity [9]. PCMs should also have desirable thermophysical, kinetic, chemical, economic and environmental properties, as pointed out by several authors [9,[78][79][80][81][82][83][84][85][86]. The optimum incorporation of PCMs within construction systems and the evaluation of the energy performance of the building with these elements is very complex and challenging.…”

An updated review on PCMs integrated into transparent building elements was recently carried out by Fokaides et al [180].…”

“…As PCMs have typically low thermal conductivity, some heat transfer enhancement techniques can be used to improve this feature as reviewed by several authors in refs. [9,79,81,83,[192][193][194]. Regarding LSF multi-layered envelope solutions, thermal bridges caused by steel elements can be used to improve heat transfer rate to the PCM-based layer.…”

The improvement of the use of renewable energy sources, such as solar thermal energy, and the reduction of energy demand during the several stages of buildings' life cycle is crucial towards a more sustainable built environment. This paper presents an overview of the main features of lightweight steel-framed (LSF) construction with cold-formed elements from the point of view of life cycle energy consumption. The main LSF systems are described and some strategies for reducing thermal bridges and for improving the thermal resistance of LSF envelope elements are presented. Several passive strategies for increasing the thermal storage capacity of LSF solutions are discussed and particular attention is devoted to the incorporation of phase change materials (PCMs). These materials can be used to improve indoor thermal comfort, to reduce the energy demand for air-conditioning and to take advantage of solar thermal energy. The importance of reliable dynamic and holistic simulation methodologies to assess the energy demand for heating and cooling during the operational phase of LSF buildings is also discussed. Finally, the life cycle assessment (LCA) and the environmental performance of LSF construction are reviewed to discuss the main contribution of this kind of construction towards more sustainable buildings.
