English Abstract

The majority of electric energy that supplied to a residential house is consumed by air-conditioning during both summer and winter.

Thus it has a major impact on the greenhouse gases and climate.

Thermal energy storage systems using phase change materials (PCMs) in building elements has become a reliable solution for energy saving.

The present study assists for the utilization of PCMs in the roof of residential buildings to absorb the heat comes from solar radiation during the daytime and releasing it to the inside nightly.

The building considerations as well as thermo-physical properties of PCMs have been taken and measured experimentally.

Results have shown that these materials have a good potential for reducing energy demand and satisfy comfortable thermal conditions.

The experimental data show that the indoor temperature increases by 4-7 oC in the winter compared to that measured in a traditional one.

Furthermore, a simulation program depended on degree-days method explained that the energy consumption could be saved up to 70%.

Thus PCMs could submit encouraging suggestions toward the sustainability.
