A conceptual framework for phase change material integration in building components

Abstract

With the recent dramatic growth of the building sector’s energy consumption to provide thermal comfort to consumers, the constraints of climate change and the scarcity of energy supplies have necessitated a wiser and more effective reduction in the amount consumed. As a result, phase change materials (PCMs) have attracted much interest as latent heat thermal storage systems in recent decades. This paper aims to explain the possibility of using PCMs in buildings by establishing an overall conceptual framework for the processes of selecting and integrating PCMs in building sector applications. Moreover, it leads to a comprehensive matrix that identifies the best and most common type of material for each building’s component, as well as its temperature and thickness properties, its thermal impact, and the most popular integration techniques. The findings show paraffin as the major used type in all building components, while salt hydrate is employed in facades. The most prevalent incorporating technique is macro-encapsulation, which prevails in most building components with its direct effect on cooling and heating applications.

Experimental and numerical analysis of the insulation performance in buildings using moisture control material including phase change materials

“…In recent years, extensive research has focused on innovative insulation alternatives, with the use of phase change materials (PCMs) standing out as a promising solution for regulating indoor temperatures [7,8]. Encapsulating PCMs within structural materials has emerged as an effective approach to enhance building energy efficiency and reduce overall energy consumption [9][10][11][12][13].…”

“…Conversely, at nighttime, the PCMs solidify and release stored heat, contributing to natural insulation and potentially reducing the need for heating [14]. Integrating PCMs as a thermal regulation strategy offers multiple benefits, including increased energy efficiency by managing temperature imbalances, enhanced occupant comfort by creating a stable indoor environment, and environmental sustainability through reduced greenhouse gas emissions associated with traditional heating and cooling systems [8].…”
