Energy demand in buildings has been observed to rise sharply in recent years. The consumption of energy is mostly for Heating and Air Conditioning of building envelope, for providing a comfortable thermal environment. Capric Acid (CA) is a Phase Change Material (PCM) competent at absorbing and discharging heat energy by altering its physical state. Such PCMs may be incorporated into construction materials to improve the energy performance of the building. This paper evaluates CA`s potential as PCM by analyzing the thermal performance of building with different conventional wall materials and CA by employing DesignBuilder simulation software. Test results indicated that CA has the prospects of enhancing the thermal performance of the building. The inclusion of CA in building wall material has improved the thermal comfort hours by a minimum of 6.5%, and a minimum of 15% energy savings can be made in the building. On comparing CA with the existing thermal buffer, viz. Expanded Polystyrene (EPS), CA, was observed to provide longer thermal comfort hours. The performance of CA was more remarkable in wall materials where their natural thermal performance is low. This study emphasizes the importance of incorporating CA as PCM in building wall materials.
