Energy audit focuses on equipment energy consumption such as lighting, air-conditioning system, elevators, and other devices operating on electricity. Data of the energy consumption recorded are used to identify and rectify by presenting detailed energy audit. Temperature, humidity, and CO2 emission of the building should be measured to conduct the investigation on detail energy analysis. Building utilizes major energy usage accounting to more than 30% overall energy usage. The commissioning and audit process results in the low-energy consumption and low equipment’s cost resulting in higher investment returns. This paper presents a detailed energy audit through a case study on small commercial hospital building located in Ranchi. The pre audit phase suggests that ceiling fans and fluorescent tube lights consume more than 50% of the total energy in the hospital. The energy auditing of the building resulting in annual energy savings of 7697.32 KW i.e. 35 % annual energy saving if recommended suggestions are followed. The recommendation of low-energy consuming equipment’s have payback period less than 6 years leading to higher return rate.

The main objective of this study is to conduct an Energy Auditing of The University of Jordan Hospital. This hospital is quite known, as one of Jordan’s leading hospitals in human resources and equipment; however, the energy consumption of the hospital over the past few years has proven to be highly expensive. This makes the saving on costs of energy consumption a high priority that cannot be ignored. Energy audit covers the three main sections of the hospital: the Emergency Building, the Clinics Building and the Main Hospital Building. The consumption of energy, which costs the hospital a total of 2,778,426 JD/yr., can be categorized into three main parts, the lighting system, the diesel fuel consumption, and the consumption of water. After analyzing the energy invoices, and visiting the site for inspection, a list of recommended solutions that are applicable to cut down the total energy bill were derived. The implementation of renewable energy was suggested and studied of which a solar water heating system was proposed. A study on photovoltaic cells technology was performed for a sample of guest's rooms, the number of panels needed was found. After that, a feasibility study was conducted. The initial costs, annual savings and payback periods of the suggested system were estimated by the current market prices. It is found that the energy auditing and the solutions would be very beneficial as it will save a total annual value of 346,853 JDs (12.5% of the current energy bill).

In this study, the energy consumption of three government and three private office buildings in Lucknow was investigated, and the energy performance index (EPI) for each building was determined. The main purpose of this research was to assess the energy usage of the buildings and identify factors affecting the energy usage. An analysis was performed using data from an energy audit of government buildings, electricity bills of private office buildings, and an on-site visit to determine building envelope materials and its systems. The annual energy consumption of buildings has been evaluated through EPI. The EPI, measured in kilowatt hour per square meter per year, is annual energy consumption in kilowatt hours divided by the gross floor area of the building in square meters. In this study, the energy benchmark for day-time-use office buildings in composite climate specified by Energy Conservation Building Code (ECBC) has been compared with the energy consumption of the selected buildings. Consequently, it has been found that the average EPI of the selected buildings was close to the national energy benchmark indicated by ECBC. Moreover, factors causing inefficient energy consumption were determined, and solutions for consistent energy savings are suggested for buildings in composite climate.

Didik Ariwibowo, in this paper explain that energy audit activities conducted through several phases, namely: the initial audit, detailed audit, analysis of energy savings opportunities, and the proposed energy savings. Total energy consumed consists of electrical energy, fuel, and materials in this case is water. Electrical energy consumption data obtained from payment of electricity accounts for a year while consumption of fuel and water obtained from the payment of material procurement. From the calculation data, IKE hotels accounted for 420.867 kWh/m2.tahun, while the IKE standards for the hotel is 300 kWh/m2.tahun. Thus, IKE hotel included categorized wasteful in energy usage. The largest energy consumption on electric energy consumption. Largest electric energy consumption is on the air conditioning (AC-air conditioning) that is equal to 71.3%, and lighting and electrical equipment at 27.28%, and hot water supply system by 4.44%. Electrical energy consumption in AC looks very big. Ministry of Energy and Mineral Resources of the statutes, the profile of energy use by air conditioning at the hotel by 48.5%. With these considerations in the AC target for audit detail as the next phase of activity. The results of a detailed audit analysis to find an air conditioning system energy savings opportunities in pumping systems. Recommendations on these savings is the integration of automation on the pumping system and fan coil units (FCU). The principle of energy conservation in the pumping system is by installing variable speed drives (VSD) pump drive motor to adjust speed according to load on the FCU. Load variations FCU provide input on the VSD pumps to match. Adaptation is predicted pump can save electricity consumption up to 65.7%. Keywords: energy audit, IKE, AC

The energy consumption has seen a vast increment because of which the use of non-sustainable sources has increased drastically. Due to this steep increase, the need of energy auditing and conservation has also increased. Growing demand for energy directly increases emission of effluents, causing environmental catastrophe. To tackle this problem a collaboration between energy audit and conservation conservation of energy is required. Energy audit is a procedural approach which is used for a clear description of the energy flow and energy management. This collective data helps in calculating the efficiency and minimizing operational cost. The aim of this project is to carry out the energy audit for the Electrical Sciences Block (ESB) of SRM INSTITUTE OF SCIENCE AND TECHNOLOGY.
