Abstract
The rapid growth of population, economic and technology has lead to greater energy demand. At present, the building sector is the dominant energy user. The use of renewable energy, such as PCM is one alternative to reduce energy consumption in buildings. Phase change materials (PCMs) is a material that can absorb and store heat energy when there is a surplus and release it when there is a deficit using the principle of Latent Heat Thermal Energy Storage (LHTES). Phase change material has shown great potential as an alternative for future energy systems. This is because phase change materials can be applied over a wide temperature range and are suitable for various heat storage system designs. Organic, inorganic and eutectic PCM are a type of phase change material in terms of their chemical composition. Direct incorporation, encapsulation, immersion, shape-stabilization and stable form composite PCM are several methods for incorporating PCM into a construction materials and elements. This review focused on organic PCM technologies developed for the building. The review covers the thermal characteristics of various organic PCM and their applications for thermal energy storage in buildings. The main conclusions taken from the review show the organic PCM has a great potential to applications and to enhance the thermal performance of buildings
