Construction industry is prominent sector that bestow greatly in economic & financial growth of a country. It is subjected to new innovations and techniques every year. All these innovations are to increase the longevity of the structures with a reduced cost. Abundant novel techniques are developed every year to upgrade the energy efficiency of the buildings. Energy-efficient buildings are designed to use less artificial energy and rely on natural energy more. Buildings are made energy-efficient by using many design factors and building insulation materials which prevent heat loss and makes the building airtight. Good quality design and selection of materials are prerequisites in energy-efficient building. The materials used in energy efficiency are PCM or Phase Changing Materials. Wall panels or wall boards are used in buildings to decrease the heat transfer of buildings from inside to outside. Wall boards are used to minimize the heating and cooling loads and also relax the cost of plastering and painting. The wall boards are fabricated using gypsum. Phase Changing Material can be incorporated into the wall boards by direct incorporation, immersion, shape stabilization or encapsulation. In this context, gypsum board is made by using Phase Changing Materials (PCM) like Paraffin wax in powdered form. The behavior of gypsum board with PCM is studied in this project.
