Building facade is an integral piece to the overall design of a building, which not only ensures adequate interior thermal comfort, minimizing cooling load rate but also lowering overall building energy consumption. In recent years, aluminum composite material wall (ACM) is a new decorative material that is increasingly being used by developers, designers, and architects, which led to many innovative building facade designs. It is a straightforward and versatile product that provides a weather-resistant, sound-insulation, heat-insulation, earthquake-resistant, and shock-resistant façade that is simple to install. As a result, this study proposes a perfomance of energy simulation with ACM material applied in building design using Building Energy Modeling (BEM). Energy simulation in buildings using a Building Information Modeling (BIM) system is proposed to reduce the Energy Use Intensity (EUI) and energy cost of building in its construction process. The results of this study are expected to assist architects and building managers in improving and enhancing the energy efficiency of buildings. These significant findings demonstrate the potential of using ACM wall to improve building energy efficiency.

“…Furthermore, it is concluded from the incorporation of PCM also contributed to reducing carbon emissions in buildings. Arıcı et al [30] discussed the energy-saving performance and CO 2 emission reduction potential of incorporating two layers of PCM on building exterior walls. It was found that compared to the base wall, using two separate PCM layers achieved the largest annual energy savings of 17.2% and CO 2 emission was 18.4% at the highest annual reduction.…”

Phase change material (PCM) embedded in the building contributes to enhancing indoor thermal comfort and reducing the heating load in winter by absorbing/releasing solar energy. The application effects of PCM incorporated into a single-space passive solar building with the auxiliary heating system (AHS) were investigated numerically in the six representative regions of western China. In the calculation and analysis by the enthalpy model, it was found that the effectiveness of PCM greatly depended on local climate conditions, thickness, and location of PCM. The results indicated that it was necessary to adopt the AHS for winter heating of the passive solar building. On this basis of using AHS, it showed a favorable thermal energy storage effect after the application of PCM resulting in the minimum indoor air temperature being maintained above 15°C within the comfort range stably. The integrated discomfort degree in each region was decreased by more than 96% compared to the original building, and the average temperature in Lhasa was 2°C higher than that in Urumqi. Furthermore, the highest rate of energy saving and carbon dioxide emission saving in the six regions was 19.7% and 17.4% in Lhasa, and the lowest were 4.3% and 4.2% in Urumqi, while other regions were relatively close, respectively. As a result, it can be stated that for a passive solar building using the AHS during the heating period, PCM was the most suitable for application in Lhasa, unsuitable in Urumqi, and generally suitable in other regions.

Phase change materials (PCMs) are an interesting technology due to their high density and isothermal behavior during phase change. Phase change material plays a major role in the energy saving of the buildings, which is greatly aided by the incorporation of phase change material into building products such as bricks, cement, gypsum board, etc. In this study, an experiment has been conducted with three identical small chambers made up of normal, grooved and PCM-treated grooved bricks. Before the inclusion of PCM in grooved bricks, PCM material behavior has been studied by different techniques such as DSC, TG/DTA, SEM, and XRD. Thermal properties and thermal stability were investigated by differential scanning calorimeter (DSC) and thermogravimetric analyzer (TGA) respectively. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to determine the microstructure and crystalloid phase of the PCM before and after the accelerated thermal cycling test (0, 60, 120). These three identical model rooms built were exposed at a temperature just above 40 °C with a heater. When the maximum outdoor temperature was 40-41 °C, then the temperature of the PCM-treated grooved chamber was 32-33 °C. The PCM-treated wall was tested and compared with a conventional and grooved wall. The difference between the PCM-treated grooved chamber and the untreated one was 8-9 °C. PCM-treated bricks provided more efficient internal heat retention in summer when the outside temperature increased.
