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. [ABSTRACT FROM AUTHOR]

Due to number of parameters effect with varied variety in energy of the building, it is difficult to judge about the effect of different energy efficacy approaches without simulation implements. The study focus on the annual energy consumption of an residential building simulated in Design Builder software utilizing efficient double glazing window formation with respect to traditional window. The building is in composite climate and window to wall ratio kept is 50%. The authorization of simulation results through electricity records with simulation error in the range of 1.39% - 6.89 %. Two promising strategies are proposed to management for reduction in the energy consumption, first, replacement of traditional glass with low-e double glazed unit having argon gas and secondly by double glazed window formation having air as infill material. The simulations results showed the benefit reap out of these strategies are 36.1 % and 25.04% respectively. Further, economic assessment showed that the payback period for first and second strategy is 1.43 years and 1.73 years respectively. [ABSTRACT FROM AUTHOR]
