“…However the different ventilation charging strategies do not affect the performance. Previous studies have primarily shown that PCM systems can reduce cooling demand or temperature swing in intermittently occupied buildings [1][2][3][4][5][6]. However, as the airport schedule is less uniform and different to intermittently occupied buildings, this study shows that the PCM-HX has a higher impact on the heating demand of the space during the intermediate and summer periods.…”

“…The use of these materials in different forms and applications such in building wallboards and PCM plates for the thermal control of relatively small and thermally lightweight spaces have been extensively studied in the literature [1][2][3][4][5][6]. The aim has mainly been to provide additional thermal mass to lower the indoor temperature swing and prevent overheating in the space, as well as reduce the energy demand in air-conditioned spaces.…”

This paper reports on the energy performance evaluation of a displacement ventilation (DV) system in an airport departure hall, with a conventional DV diffuser and a diffuser retrofitted with a phase change material storage heat exchanger (PCM-HX). A TRNSYS-CFD quasi-dynamic coupled simulation method was employed for the analysis, whereby TRNSYS® simulates the HVAC and PID control system and ANSYS FLUENT® is used to simulate the airflow inside the airport terminal space. The PCM-HX is also simulated in CFD, and is integrated into the overall model as a secondary coupled component in the TRNSYS interface. Different night charging strategies of the PCM-HX were investigated and compared with the conventional DV diffuser. The results show that: i) the displacement ventilation system is more efficient for cooling than heating a space; ii) the addition of a PCM-HX system reduces the heating energy requirements during the intermediate and summer periods for specific night charging strategies, whereas winter heating energy remains unaffected; iii) the PCM-HX reduces cooling energy requirements, and; iv) maximum energy savings of 34% are possible with the deployment of PCM-HX retrofitted DV diffuser.

“…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.

Thermal energy storage (TES) is an advanced technology for storing thermal energy that can mitigate environmental impacts and facilitate more efficient and clean energy systems. Thermochemical TES is an emerging method with the potential for high energy density storage. Where space is limited, therefore, thermochemical TES has the highest potential to achieve the required compact thermal energy storage. Thermochemical TES is presently undergoing research and experimentation. In order to develop an understanding of thermochemical TES systems and to improve their implementation, comprehensive analyses and investigations are required. Here, principles of thermochemical TES are presented and thermochemical TES is critically assessed and compared with other TES types. Recent advances are discussed.
