Abstract
India’s electricity demand has increased rapidly, and it is expected to rise in further years, mainly in the commercial sector due to urbanisation and economic growth. So, there is an urgent need to manage energy in the commercial buildings of India. This study investigates the use of six-sigma methodology in energy efficiency management in a retail space located in Tamilnadu, India, along with simulation and optimisation using Non sorted genetic algorithm-II. Simulation and optimisation are performed using designbuilder and energy plus tools. The energy consumption in the building is analysed using the Six Sigma approach, which helps to identify the root cause of the energy issue in the building. The energy consumption is controlled using the strategy of setpoints of Air conditioner. The Non-sorted genetic algorithm-II is performed to reduce energy consumption and total discomfort hours, which produce optimum setpoints and setback points. The top three optimum solutions are discussed. The results show 19.6%, 19.2% and 16.4% of energy reduction in the building compared to the baseline model. The results have also highlighted that energy consumption can be managed in a retail store building with the help of an efficient six sigma process and zero-cost strategies like setpoints.
