The integration of phase change materials into the buildings is a passive and sustainable way to minimise energy use in the buildings to achieve the desired thermal comfort. Phase change materials integrated into various parts of the building such as roofs, windows, walls and floors not only reduce the heating and cooling energy loads of the building, but also reduce the fluctuations in heat flux, reducing the maximum and minimum peak temperatures and improving the thermal comfort conditions in the zone. This study aims to investigate the effect of phase change material integrated into the ground floor on the heating and cooling load of the building. An office building for the city of Ankara in Turkey was modelled in three dimensions and monthly and annual energy simulations were performed using EnergyPlus-based DesignBuilder software. Inorganic-based macro-encapsulated InfiniteRPCM was selected as the phase change material to be integrated into the ground floor of the building. The effect of the phase change material at different melting temperatures (21°C, 23°C) was analysed for two different types (GF-1 and GF-2) of ground floor. According to the results of the study, it was concluded that the GF-1 type is more effective in reducing both heating and cooling load than the other construction. PCM with the 21°C melting temperature was found to be more efficient in terms of total energy saving compared to the other temperature. For GF-1 type, PCM with a melting temperature of 21°C reduced the heating load by about 12% during the heating season and the cooling load by 3% during the cooling season. The total annual energy savings for GF-1 and GF-2 were respectively calculated as 91,835 kJ/m2.year and 3,537 kJ/m2.year depending on different melting temperatures. This shows the importance of the location of the phase change material in the slab.
