A major percentage of the energy is utilised for the building sectors for cooling the building which is used for Airconditioning systems. One of the techniques for decreasing energy consumption in building systems is passive cooling. The PCM materials was integrated in the building which is isothermal temperature for storing and retrieving the energy during a phase change. The stored PCM is a constant temperature for phase change and also gives the large potential of energy during the storing and releasing energy. The integrated building wall to prevent the solar heat infiltration into buildings and controlling the indoor temperature swing. The selection and efficiency of PCMs are highly subjective to climatic conditions where they applied. In the present study, a real time PCM integrated residential building is studied through numerical simulation using Design Builder software in moderate climatic condition in Bangalore city, India. The result shows that throughout the year, the PCM room does not required any air-conditioning device for cooling application.

“…Windows were identified to be the retardant in reducing the building energy consumption. Lately, many research have been carried out that using Phase Change Material (PCM) as part of the building walls material and proven that it can reduce the building energy [24][25][26][27]. A double-glazed window unit with a sandwich 12mm gap filled with technical grade paraffin as a phase change material (PCM) was examined on its thermal performance and the results show the PCM curtailed the energy consumption effectively [28].…”

Green building, net-zero energy building, low energy building, and sustainable building are the common terms being used in the building industry nowadays, with the primary aim to produce buildings with low energy and low carbon dioxide (CO2) emissions. Different types of building materials can have significant implications for energy efficiency, especially in the warming climate. The energy crisis, future global warming, and climate change can be mitigated by choosing the right building materials, which will also lower the building's energy consumption and carbon dioxide emissions. This paper presents the effects of different building materials on the cooling capacity and cooling energy consumption of a building for four (4) different climate change weather data, namely, the present time scenario, the 2020s, 2050s, and 2080s time scenario using TRNSYS simulation software. The main library of a university in Petaling Jaya, Malaysia, was chosen as the case study. Three (3) types of building materials were studied, namely, Type 1 (brick walls with single-glazed windows), Type 2 (foam insulation cavity walls with double-glazed windows), and Type 3 (air gap cavity walls with double-glazed windows). The simulation results showed that the Type 2 building materials could reduce the yearly cooling energy consumption by 14.5%, compared with the current building materials (brick walls with single-glazed windows). The Type 3 building materials (air gap cavity walls with double-glazed windows) with the lower installation were wound to reduce the yearly cooling energy consumption by 9% compared with the Type 1 building materials. For architects, designers, politicians, and library administrators, the research's conclusions have immediate practical implications that will help them make decisions and implement energy-saving plans. In the end, this research helps libraries in Malaysia remain sustainable and resilient in the face of global warming and the energy crisis.

“…During the phase transition, PCM could stably absorb or release a large amount of latent heat in a narrow temperature range. Therefore, PCM is widely used in thermal energy storage and thermal management fields, such as materials in smart buildings, − thermal management of batteries, − temperature-regulating fabrics, and solar heat storage systems. ,− …”

Microencapsulation of phase-change materials (PCMs) is of great value and significance for improving energy efficiency and reducing carbon dioxide emissions. Here, highly controllable phase-change microcapsules (PCMCs) with hexadecane as the core material and polyurea as the shell material were developed for precise temperature regulation. A universal liquid-driven active flow focusing technique platform was used to adjust the diameter of PCMCs, and the shell thickness can be controlled by adjusting the monomer ratio. In synchronized regime, the droplet size is only related to the flow rate and excitation frequency, which can be accurately predicted by the scaling law. The fabricated PCMCs have uniform particle size with a coefficient of variation (CV) under 2%, smooth surface, and compact structure. Meanwhile, under the good protection of a polyurea shell, PCMCs exhibit fair phase-change performance, strong heat storage capacity, and good thermal stability. The PCMCs with different sizes and wall thickness show obvious differences in thermal properties. The feasibility of the fabricated hexadecane phase-change microcapsules in phase-change temperature regulation was verified by thermal analysis. These features indicate that the developed PCMCs by the active flow focusing technique platform have broad application prospects in thermal energy storage and thermal management.
