The Integration of PCMs with Local Materials in Arid Zones in Algeria

Abstract

This study explores the integration of Phase Change Materials (PCMs) with traditional local materials in the context of arid climatic zones in Algeria, with the aim of improving indoor thermal comfort and reducing energy consumption. A traditional Mozabite house in Ghardaïa was selected as a case study due to its compact architecture and passive design strategies. Using Design Builder simulation software, the thermal performance of the house was analyzed in two scenarios: with and without the incorporation of PCMs. The results indicate that PCMs integration can reduce indoor temperature peaks by up to 3°C, improve thermal comfort rates, and lower CO₂ emissions. The study demonstrates the effectiveness of combining vernacular architecture with modern thermal materials to create sustainable and energy-efficient housing in hot climates.
