The Strategy of Using PCMs in Building Sector Applications

Abstract

With the recent large increase in the building sector's energy use to provide thermal comfort to consumers, the restrictions of climate change, and the scarcity of energy supplies, there has been a need to develop ways to reduce energy consumption. The use of phase change materials (PCMs) as a thermal energy storage (TES) system has attracted a lot of attention as a technique to improve thermal performance, conserve energy, and improve occupant comfort. When storing energy via phase change, the key advantage in terms of building materials is the higher energy density, which indicates that more energy can be stored in a constant volume. This study focuses on the vital role of PCMs in building applications by presenting the different classifications of PCMs as well as their integration techniques, systems, and benefits for building applications. Different case studies for full scale buildings are presented. A design strategy is concluded for integrating PCMs in buildings.

A conceptual framework for phase change material integration in building components

“…Further study of cases of building destruction and maintenance that contain PCMs is necessary in order to guarantee proper management and avoid the danger of leakage or other hazards. 103 Additional study is needed to optimize the phase change parameters of the phase change envelope and how to make it more cost-effective and comfortable to use in buildings on a wide scale, and how to better satisfy the needs of different building types in different climates, and so on. 104…”

Improvingurban Energyresiliencewith an Integrative Framework Based on Machine Learningmethods

“…Thus, the urban energy resilience (UER) concept is seeing increasing application in the fields of climate change, sustainability, and natural disaster risk analysis. Meanwhile, climate change and global warming present numerous challenges to energy resources in cities and urban areas (Ismail et al, 2022b;EL-Mokadem et al, 2016b;Noaman et al, 2022;Perera et al, 2021;Sharifi and Yamagata, 2014a). In fact, 60 to 80% of global energy is consumed in urban areas (Hassan et al, 2020a(Hassan et al, , 2020bOlazabal et al, 2012;Sharifi, 2019;Sharifi and Yamagata, 2016a), which can lead to negative consequences, for instance an increase in blackouts and grid failures (Erker et al, 2017;Sharifi and Yamagata, 2016a).…”
