“…Another example of using PCMs in opaque partitions is the use of foamed cement with a PCM, as described by Li et al [53]. The effects of the test composite were verified in five climate types in China, and the results demonstrated that PCMs performed the most effectively in a temperate, warm climate.…”

This paper presents a detailed analysis of the research into modern thermal energy storage systems dedicated to autonomous buildings. The paper systematises the current state of knowledge concerning thermal energy storage systems and their use of either phase change materials or sorption systems; it notes their benefits, drawbacks, application options, and potential directions for future development. The rapid proliferation of studies on installation systems, new composites, and phase change materials requires a systematisation of the subject related to short- and long-term thermal energy storage in building structures. This paper focuses on assessing the validity of the current improved thermal energy storage solutions for buildings with very high energy efficiency standards and buildings that are energy-independent. The paper presents the current results of the energy and economic analyses of the use of heat storage systems in buildings. This paper shows the optimal heat storage systems for autonomous buildings. Moreover, it also shows other potential ways to develop systems and composites capable of storing heat in autonomous buildings.

In India, the residential sector currently accounts for 26% of total electricity consumption, a figure anticipated to surge to 38% by 2030 and 39% by 2047. This escalation is primarily attributed to the growing prevalence of air conditioning systems, serving to achieve thermal comfort in both urban and rural settings. To align with Sustainable Development Goal 11 (SDG11), fostering environmentally friendly practices, integrating energy-efficient products, and employing sustainable techniques in the residential sector become imperative.Among the various strategies, the adoption of energy-efficient building envelope designs emerges as a pivotal approach in curbing operational energy consumption. This study investigates the impact of different building envelope materials on energy consumption in residential buildings, employing an optimization study utilizing the e-Quest simulation tool. The research focuses on an existing residence in Gurugram, Haryana, situated in a composite climate. A notable aspect of the study is the exploration of the most influential building envelope component-whether walls, roofs, or fenestrations-in achieving maximal energy consumption reduction.The findings show the significance of designing building envelope components, particularly walls, roofs, and fenestrations, to minimize heat gain and maximize energy consumption reduction. Notably, energy-efficient walls exhibit a more pronounced impact than other components. Lightweight concrete walls emerge as more energy-efficient than counterparts with cavities, AAC blocks, concrete blocks, cellular concrete, and bricks, showcasing substantial variations in energy consumption reduction. The introduction of insulation materials proves to be a crucial factor, contributing significantly to reduction in energy consumption combined with any wall material. Collectively, an energy-efficient building envelope design presents a remarkable potential to reduce operational building energy consumption by approximately 18%.

“…In this context, PCM can store or release a large amount of heat during the phase change process and are widely preferred in these systems (Lewis et al , 2004). Applications of PCMs have many including buildings (Kalbasi et al , 2023; Li et al , 2022), refrigeration (Bista et al , 2018; Schalbart et al , 2015) and thermal management of solar (Stalin et al , 2021; Venkatesan et al , 2022) and electronics systems (Mozafari et al , 2021; Nirwan et al , 2022). Despite having many benefits, most PCMs have a low thermal conductivity problem.…”

Purpose The purpose of this study is to examine the effects of inclination angle on the thermal energy storage capability of a phase change material (PCM) within a disc-shaped container. Different container materials are also tested such as plexiglass and aluminium. This study aims to assess the energy storage capacity, melting behaviour and temperature distributions of PCM with a specific melting range (22°C–26°C) for various governing parameters such as inclination angles, aspect ratios (AR) and temperature differences (ΔT) and compare the melting behaviour and energy storage performance of PCM in aluminium containers to those in plexiglass containers. Design/methodology/approach A finite volume approach was adopted to evaluate the thermal energy storage capability of PCMs. Five inclination angles ranging from 0° to 180° were considered and the energy storage capacity. Also, the melting behaviour of the PCM and temperature distributions of the container with different materials were tested. Two different AR and ΔT values were chosen as parameters to analyse for their effects on the melting performance of the PCM. Conjugate heat transfer problem is solved to see the effects of conduction mode of heat transfer. Findings The results of the study indicate that as AR decreases, the effect of the inclination angles on the energy storage capacity of the PCM decreases. For lower ΔT, the difference between the maximum and minimum stored energies was 20.88% for AR = 0.20, whereas it was 6.85% for AR = 0.15. Furthermore, under the same conditions, the PCM stored 8.02% more energy in plexiglass containers than in aluminium containers. Originality/value This study contributes to the understanding of the influence of inclination angle, container material, AR and ΔT on the thermal energy storage capabilities of PCM in a novel designed container. The findings highlight the importance of AR in mitigating the effect of the inclination angle on energy storage capacity. Additionally, comparing aluminium and plexiglass containers provides insights into the effect of container material on the melting behaviour and energy storage properties of PCM.
