Solar energy can be used through a thermal storage medium like phase change material (PCM) and decrease active
energy consumption through heating, ventilation and air conditioning (HVAC) systems in buildings. This could
be possible by applying the best suitable thermal energy storage technique (TES) to building envelopes or
compartments of building such as floors, walls and ceilings [1]. Fatty acids as solid-liquid (S-L) PCMs are gaining
attraction for TES applications in buildings because of good latent heat thermal energy storage (LHTES)
characteristics such as high latent heat, suitable S-L phase change temperature, good thermal stability and thermal
reliability, no phase separation, slightly subcooling, relatively little corrosivity and low price [2]. The eutectic
mixtures of such type PCMs allow for tailoring their phase change temperatures according to different passive
solar TES targets.

Abstract
Due to the rapid economic improvements the energy shortage and environmental matters have become
more important issues. Therefore, improving energy utilization efficiency and protection of environment is a
significant subject. In this sense, energy storage method becomes prominent for matching the thermal energy
supply and demand in time or space. Through Latent Heat Thermal Energy Storage (LHTES) a higher energy
storage density a smaller size of the system and a narrower temperature range during the melting and freezing
process of phase change materials (PCMs) might be achieved. PCMs have been found attractive for their diverse
applications in building energy efficiency, solar heating systems and air-conditioning systems.
