“…Thus, building energy efficiency and energy conversation has become hot topic worldwide [3][4][5][6]. A thermal energy storage system is considered one of the most effective methods of improving building energy efficiency, and increased attention has been paid in recent decades in optimizing the necessary techniques for thermal energy storage applications, particularly in buildings [7].…”

“…PCMs can also be encapsulated in separate storage systems for active heating or night cooling. In a recent research project of buildings called "MECLIDE", which was conducted by Alvarez et al [5] from Spain, PCMs were encapsulated in containers which then form parts of the building structure in order to increase the thermal inertia of the building and also to work as an active solution. However, incorporating PCM into traditional building structures is still a frequently used method.…”

Abstract:Incorporating Phase Change Materials (PCMs) into traditional building structures has been considered as an effective way to reduce the mismatch between energy supply and demand and in turn to minimise energy consumption (cooling/heating energy). For building applications, Phase Change Material Wallboards (PCMWs) are of particular interest due to their easy installation to existing buildings for refurbishment. Both interior and exterior PCMWs are investigated in this paper, with a numerical study examining the effects of wallboard thermal properties on its thermal performance. These influencing factors include melting temperature, melting range, latent heat, thermal conductivity and surface heat transfer coefficient. An effective heat capacity model is adopted to consider latent heat with the model validated by an experiment. Inner surface temperature and diurnal energy storage are chosen as the evaluation criteria when comparing the thermal performance between different PCMWs. By analysing the effects of influencing factors on the system thermal performance, this study serves as a useful guide for selection of PCMs in energy-efficient buildings.

“…Several passive PCM-based TES solutions for buildings have been studied during the last decades, for both opaque and window facades, such as PCM enhanced drywalls [2,[89][90][91][92][93][94][95][96][97][98][99][100][101][102][103][104], SSPCM elements [105][106][107][108][109][110][111][112][113][114][115][116][117][118][119][120], PCM-based ventilated facades [121][122][123][124][125][126], PCM-shutters and PCM-window blinds systems [127][128][129][130][131], interior sun protections with PCMs [132,133], translucent PCM walls [134]…”

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.
