    ANALYTICAL STUDY TOWARDS A THERMAL APPROACH OF PHASE-CHANGE MATERIAL IN DRY & SEMI-ARID CLIMATE
    (UMT, Lahore, 2021) Hafiza Mahnoor Asim
    It is estimated that buildings use more than half of their total energy usage for the heating/cooling of their inside environments. Consequently, the development of innovative materials to boost the energy consumption of buildings is becoming more necessary. This has increased interest in integrating PCM into structures during the past several decades. In a small temperature range, PCM can absorb a significant amount of heat during phase transitions. When utilized in the building envelope, PCMs may help to lower the amount of heat that is transported into the internal environment while also saving energy by reducing the amount of cooling power that is consumed by the HVAC system. The effectiveness and selection of PCM, on the other hand, are dependent on the environment in which it is used. A hot-humid climate, which is defined by consistent daily temperature across the year, might give a year-round chance to profit from PCMs in the context of building application, according to research. The modest diurnal temperature change, on the other hand, may have an impact on the performance and efficiency of the PCMs. An investigation of the capacity of PCMs to lower the peak indoor temperature (Ti) of organically conditioned buildings in a humid climatic zone is presented in this research. To do this, field measurements have been carried out in existing facilities to determine the suitable transition temperature range for PCM applications and run analysis to prove its capability practically to inspire the rest for further research in future.
