In this paper, the effectiveness of phase-change material (PCM) for demand response in a residential building is evaluated. PCM serves as a thermal energy storage which stores latent heat (during preheating) in the building's envelope and releases it for use in response to varying price signals. With the PCM, the heating, ventilation and air conditioning (HVAC) system is optimally scheduled through a home energy management system (HEMS) leading to a reduced winter heating cost and a more comfortable indoor temperature profile. The outdoor temperature on one of the coldest days in Sydney (26th June, 2016, based on average daily temperature) is used as a case study. The effects of PCM thickness, heating tariff scheme and the preferences of the home owner on performance of the PCM are investigated. The analysis of the results shows that with cost minimization as priority, considerable cost savings can be achieved with PCM and with thermal comfort as priority, a better indoor temperature profile is also achieved with PCM.
