Abstract:

This paper emphasizes the application of phase change thermal storage technology in green buildings and its profound impact on building performance. Through detailed analysis and discussion, we examine the practical implementation of phase change thermal storage technology in building envelope structures, air conditioning systems, and hot water systems, as well as delve into its multifaceted influence on building energy consumption, indoor thermal environment, economy, and environmental friendliness. The findings reveal that phase change thermal storage technology not only significantly reduces building energy consumption and enhances indoor thermal environment but also boosts the economic and environmental sustainability of buildings. However, despite its evident advantages, the technology still encounters certain challenges in practical applications. Looking ahead to future trends, phase change thermal storage technology is expected to play an even more significant role in green buildings. Consequently, we propose pertinent policy suggestions and measures to promote the widespread application of phase change thermal storage technology in green buildings, thereby advancing sustainable development within the construction industry.
