The manufacturing of a structure’s exterior walls and top covering seldom uses phase change materials (PCMs). Thus,demonstrating an unsuccessful approach towards enhancing the energy efficiency of said building. The extensive examinationthat has been carried out over the past two decades has revealed the potential abilities of PCMs in terms of energy preservationin building envelopes. However, the significant fiscal burden associated with PCMs’ use has prevented their widespreadadoption. This scholarly article provides a thorough assessment of a unique PCM that incorporates naturally occurring fattyacids and glycerides into flyash pellets, while also assessing its performance in relation to applications involving buildingenvelopes. To attain an intended result, the PCM-flyash pellets were combined with nanoclay ceramic insulation. sprayed toa test building outside wall and observed over several months in a hot, humid environment. In order to demonstrate howwell the PCM-flyash-enhanced nanoclay insulation reduces heat gains and losses in the building envelope, A comparison wasdone using a section of wall that was entirely insulated with nanoclay ceramic material. To further comprehend how thePCM-flyash pellets influenced the wall heating as well, the test wall’s numerical modelling was conducted. Experimental datawere used to test the concept initially.
