Incorporating phase change materials in buildings material for energy conservation.

Number: pap. 759

Author(s) : BOUGUERRA E., HAMID A., RETIEL N.

Summary

The effect of phase change material (PCM) integration in building components is investigated in mild climates. The incorporation of PCMs in building materials is particularly interesting since it permit to the thermal storage to become a part of the building structure and is completely passive. Simulations in a typical family house were made and the effect of incorporating PCMs on different buildings components was analyzed. Results show important reduction in cooling energy even in mild climates characterized by low day/night temperature swings. Even if large quantities of PCM are necessary, a reduction of 20% can be obtained with reasonable thickness of PCM wallboards. The best position for PCMs is found to be on surfaces that undergo large temperature variations or connected to the outdoor air. The ceiling for example, presents the better compromise between energy reduction and PCM quantity used.
