Abstract: This work deals with the performance analysis of incorporation of a phase change material (PCM) in building construction as micro capsules instead of macro encapsulation. Micro capsules are used in various applications, particularly in construction for passive exchange of heat across walls and roof. Completion of basic study leads rice bran distilled fatty acid-grade-A (RBDFA)/melamine formaldehyde (MF) as the suitable core PCM and covering material, respectively for the test site. Micro RBDFA capsule's thermo-physical properties were studied using thermo gravimetric analysis (TGA), Fourier transform infrared spectrophotometer (FT-IR) and differential scanning calorimeter (DSC) and all test results satisfied the basic requirements. Two model blocks were constructed, one with macro encapsulated RBDFA roof and another one with micro encapsulated RBDFA roof. Temperature variation inside the model blocks was observed. The results indicated that, inclusion of micro encapsulated RBDFA in construction gives positive effect to maintain less temperature variation at indoor that is 5-7°C less than ambient condition.
