Abstract
The energy efficiency in the building sector is becoming a real issue to be handled to minimize the energy consumption and contribute to prevent the global warming influencing all the world. In this context different researchers have developed solutions to improve the use of solar energy in building envelopes. Phase change materials (PCM) have shown their ability to store energy during the day and release it during the night allowing indeed a significant reduction of energy load. The present paper aims for the performance analysis and energy saving potential of a building envelope composed by hollow brick filled with PCM considering different scenarios. This innovative material has been developed in previous studies considering just the material scale or the component scale, but the building scale has not been considered in enough studies, where it concerns just the use of PCM as a layer or a mortar. Results found by conducting a numerical simulation with difference finite method showed a good energetic performance when incorporating PCM into bricks envelope described by a reduction in temperature fluctuations by about 3°C on average and energy saving rate reaching 41% with the optimum disposition of the appropriate type of hollow brick materials.
