Energy management schemes and policies are validated methods and policy instruments for the implementation of sustainable energy production in manufacturing and other industries. This paper describes the estimated electricity consumption and expense findings at a large building in Bangladesh subtropical Dhaka Town. Also, the energy management criterion and the saving. Energy management becomes a requirement for long-term sustainability which cannot be overemphasized. Compliance with the United Nations Framework Convention on Climate Change agreements is also a fetal factor. Energy efficiency is only one fundamental requirement for green buildings. According to the observation it is obtained that air conditioning was found to be the largest end-use of power, accounting for more than 32 per cent of the total energy consumption of building. Lighting is another higher power consuming equipment. Lighting electricity usage varies from 2 to 10 per cent of overall power based on the size of industry. Innovation and quality improvement in the lighting industry have created significant opportunities for energy saving in this area. Lighting is an area which, apart from good operational practices, provides a major scope for achieving energy efficiency at the design stage by incorporating modern energy efficient lamps, luminaires, and gears. In the previous year of the implementation the energy use per square meter is about 109.82 kWh which drop down to 95.87 kWh within one year. The electricity consumption is drop about 12.7% within the first year. The cost analysis and payback times were determined in this Energy audit by replacing the higher consumption equipment with Energy-efficient equipment. The benefit of introducing energy efficiency programs in buildings is significant in terms of both carbon production and cost savings.
