Economic computation and simulation for different window formations in reducing energy consumption in building sector

Energy consumption has become the challenge especially in developing countries such as India and China. In recent times, increasing fears about the environmental impressions of energy consumption and global warming has exaggerated this concern. The building sector is consuming one-fourth of the share at state level power consumption in Punjab where the procurement of coal even becomes the challenge and thermal plants needs to be stopped leading to almost blackout in the state. This paper examines the energy saving conformations leading to reduction in energy management of the building. To achieve this, a residential building is modeled in Design builder software and simulation is carried with Energy Plus integrated tool. In this paper, simulation were carried out with variety of double glass formations with infill material such as argon and air in gap of 12 mm. Full year simulation was performed for the composite climate. Simulation results indicated the considerable reduction in solar gains by 28.28% and cooling load by 27.08%. Further, initial assessment was carried out by calculating approximately the cost of double glass unit and payback period for different window formations. It is recommended to use the double glass unit empanelled window formation which has the potential to reduce the electricity bill considerably. The initial cost is approximately 2.12 times more than traditional window which be offset by the savings over energy consumption.
