Energy consumption for thermal comfort in buildings has grown a lot in few years because of increasing users demand for comfort conditions and the associated market penetration of more heating systems. In Korea, radiant floor heating system has been used in residential buildings traditionally. This type of residential buildings consume approximately 55% of the total residential building energy consumption in heating. Therefore, any decrease in heating energy consumption will significantly reduced total residential building energy consumption. Thermal energy storage is a useful tool for improving energy efficiency and increasing energy savings. In latent heat thermal energy storage systems, energy is stored during melting and recovered during freezing of a phase change material. In latent heat thermal energy storage systems (LHTES), energy is stored during melting and recovered during freezing of a phase change material (PCM). This study aimed to prepare the composite PCMs with low mass fraction of exfoliated graphite nanoplatelets (xGnP) to obtain applicable PCMs as building materials and to investigate the effect of xGnP addition on thermal conductivity, melting temperature and latent heat capacity of PCMs, in order to satisfy thermal comfort of residential building using radiant floor heating system with energy conservation.

Recently, increasing the energy consumption has being environmental issue in the world. Also energy consumption ratio of building in total energy consumption is getting increasing. Therefore, development of building materials needs for energy saving. PCM (Phase change material) has a good potential because it stored heat energy as a form of latent heat during phase change. However, application of PCM as itself for building material is difficult due to its phase stability of liquid state. It can overcome through the microencapsulated PCM (MEPCM). A many studies had analyzed that PCM has good potential as application for various fields. This paper indicates the characterization of PCM for application of building material through the microencapsulated PCM.
