Advances in Constructional Engineering

With the growing prominence of building energy consumption issues, the application of phase-change materials in architectural walls has become a research hotspot. Leveraging their characteristic of undergoing phase transitions at specific temperatures to absorb or release latent heat, these materials effectively regulate indoor temperatures and reduce building energy consumption. This paper provides an in-depth analysis of the thermal storage and temperature regulation mechanisms of phase-change materials in building walls, examines various factors influencing their performance, comprehensively introduces common application methods, and conducts a comprehensive evaluation of practical effects. The research findings are expected to provide robust theoretical support for the widespread application of phase-change materials in construction and the enhancement of building energy efficiency.
