Electricity is a crucial part of our everyday lives. A limited number of resources can be utilized to generate power; hence, one must save these resources or electricity for future utilization. is is only possible by using energy most efficiently. For sustainable development and energy conservation, energy auditing plays an indispensable role. e energy audit is an extensive study that helps to identify energy use among different services and provides opportunities for energy conservation. e literature showed various energy audits conducted at various locations with its analysis. Few were shown that the appliances are responsible for high energy consumption, and few talked about the cost analysis with energy-saving methodologies. is work is proposed to combine the integration of renewable energy sources in a building and the cost-saving due to energy-efficient appliances. is paper tries to observe, infer, and analyze the patterns of energy usage of a residential complex and various measures to reduce energy consumption and cost-saving. A case study is included to analyze the reduction in consumption of energy per unit to make the building energy efficient. A feasibility study is executed to observe the increments in costs. Calculations for auditing will reduce the building’s carbon footprint and benefit residents in the form of cost savings in the long run. 1.Introduction In the residential segment across India, the present elec- tricity consumption is about 25% of the total electricity consumption according to data published (2018-19). e electricity demand in residential buildings is at a simple annual growth rate of 10–14%. is is because of the in- creasing population economic and technological develop- ments. To ensure that energy usage does not become unmanageable, which now poses a present-day challenge, the issue also provides an opportunity to address and resolve energy management problems in different areas. Energy auditing is efficiently done for energy conservation. e various steps involved are performed by inspecting, surveying, and analyzing energy flow in a building, framework, or system. e result has increased based on analyzing the energy consumption of Two-story buildings in France. In an academic institution located in Nigeria, a study was conducted to project energy consumption on various time scales such as daily, weekly, and annual. It was con- cluded that HVAC (heating, ventilation, and air condi- tioning appliances) and gadgets driven by electrical motors consumed 36% and 61.9% of the total energy supplied [1]. e electrical energy consumption at Airport, in Egypt, was analyzed by considering various indoor parameters such as temperature, illuminance, and relative humidity. It was shown that there was a 24.5% reduction in total energy consumption by increasing the air cooler temperature by 2 ° C Hindawi Advances in Civil Engineering Volume 2022, Article ID 4400874, 10 pages https://doi.org/10.1155/2022/4400874
