One such method widely studied and applied over the last decade is the use of Phase Change Materials (PCMs) often applied to building components as thermal energy storage systems. This study focuses on BioPCMs – particularly one microencapsulated with a roof coating called IntelliKoat developed by an Arizona-based company called EnKoat. Through EnergyPlus, validated with real building data, the effect of the coating on energy consumption and cost savings were analyzed while quantifying reductions in thermal resistance values for the roof. The study found that integrating IntelliKoat allowed a 1.04% energy reduction, i.e., 15,145 kWh annually. The coating also demonstrated marginal improvements in thermal resistance, room air temperatures and roof surface temperatures. It should be noted that this building is not designed for thermal comfort, instead it is an archive for storing books to be maintained at 50 oF (o10 C) throughout the year. This research provides an insight into optimizing PCM-based coatings for commercial building applications in hot arid regions like Arizona.
