The present society utilizes the electrical energy for their comfort. This electrical energy is majorly obtained by burning the fossil fuels. These fuels are decreasing in a dramatic rate and it is also contributes to the pollution. Throughout the sun's daily and annual cycles, thereby the reducing the dependence of energy consuming mechanical and electrical systems of heating and cooling. Based on the analysis of data collection, Passive solar design for home helps to reduce the consumption of electrical energy by utilizing the solar energy. Passive solar design is a green concept which is aimed to utilize the maximum solar energy in the form of heat to maintain interior thermal comfort by designing windows, walls and floors of the homes to collect the solar heat from the sun in winter and reject it in the summer. This papers presents the critical literature review on benefits due to passive solar energy system in building.
