Perspective role of phase change materials for energy efficiency in Algeria

Abstract

Various measures have been considered in Algeria to improve energy efficiency but other effective ways are promising such as integration of phase change materials. The potential of these smart materials is reviewed for energy efficiency improvement in various systems including energy storage, refrigeration, and air conditioning, building envelope as well as cooling of photovoltaic systems. The literature review shows the high potential of this new class of materials. The survey indicates up to 12% energy savings due to integration of these new materials in refrigeration, 17.82% for air conditioning systems, and 10% for photovoltaics. The highest impact was achieved for the building envelope where energy savings of 34.8% were reported. On the other hand, limitations, challenges, and future concerns are revealed and highlighted for both researchers and policy-makers. New eco-friendly materials should be searched and adapted to the Algerian climate zones. Artificial intelligence can be a handy tool for material selection and optimization of thermal performance. Investment should be implemented together with adequate policy and awareness. Finally, the Algerian building regulations should be updated to include this new class of materials in buildings.
