Abstract : The building sector consumes 35% energy for the cooling/heating of the buildings. To diminish the energy consumption of the buildings, it is necessary to advance the research on passive cooling/heating methods. The development of new and advanced materials for building components will provide a lesser environmental impact. The phase change materials (PCM) integrated with the building wall can store the latent heat thermal energy system. This will be reducing and shift the thermal load on buildings during the transition of phase change solid to liquids. In this present work, the real-time residential building is modeled and simulated using Energy Plus software with and without the use of PCM residential buildings. The building energy scenario for PCM and non-PCM buildings is discussed in warm and humid (Chennai), moderate (Bangalore), and composite (Delhi) climatic conditions. The PCM buildings are the major reduction of annual electricity consumption, annual energy use intensity, and annual energy demand are compared to non-PCM buildings. The PCM building HVAC’s load is reduced by around 40% than that of non-PCM buildings. The PCM building is more suitable for providing indoor thermal comfort for the occupants.
