Phase-changing materials (PCM) have many uses. One of the important areas of use is to
increase the heat retention capacity of building components. Researches are carried out on the heat retention capacities of PCMs to store energy in building components and to ensure building temperature
control. The use of PCM in building components has become an important tool for energy saving, since
ensuring building temperature control in summer and winter conditions is a situation that requires continuity. This feature provided to the building component provides an improvement in the energy identity
of the building. In general researches, the use of macro, micro and nano encapsulated PCM decreases
the heat conduction coefficient as it increases the heat retention capacity of the building components,
but decreases the strength. However, when the capsule size used in micro capsule applications is reduced
to 7 microns and below, it is seen that the strength increases, while the thermal conductivity coefficient
continues to decrease. As a result, the compressive strength of the component can change positively or
negatively due to the addition of PCM to the building component. However, due to the continuous increase in the PCM ratio of the building component, the heat holding capacity of the building component
increases and its thermal conductivity decreases.
