“…The energy audit is a consistent and useful tool for overcoming technological, information bottlenecks, and investment in energy-efficient measures [2]. The measurement [14] of data as a primary data collection is to understand the operation and event occurrence, calculate, explain, and validate the industry's energy consumption.…”

“…As per Energy Conservation Act, 2001, energy audit is defined as verification, monitoring, and analysis of the use of energy, including submission of technical report containing recommendations for improving energy efficiency with cost-benefit analysis and an action plan to reduce energy consumption. Energy auditing is a systematic approach for energy management and the first step in realizing the energy efficiency opportunities [2] with economic [3] consideration. The industrial energy audit is mainly focusing on the energy loss reduction [4] in the following aspects of the process, the operation modification, investment in energy-efficient technologies, load management, and conversion energy losses.…”

According to the International Energy Agency’s estimation, Indian primary energy demand is expected to increase by about 1250 Mtoe and 1500 Mtoe by 2030. The 3 M management concept now changed into a 4 M management concept that includes energy management. In the case of energy management, the electrical energy sector assumes critical importance. An energy cost occupies nearly 30-40% of the production cost in small and medium-size enterprises (SMEs). Bureau of Energy Efficiency (BEE) has initiated a separate energy efficiency intervention to the SME’s, where the energy-efficient technologies, operational procedures, and proper awareness programs to SMEs are stated. This paper discusses the complete electrical energy audit on a small-scale Siddha and Ayurveda medicine industry. The traditional medicine manufacturing technologies make the process complex (process loads are intermittent/interlinked) during analysis. Hence, the detailed energy auditing/conservation studies on the power factor/harmonics were carried out without affecting Indian traditional medicine manufacturing technology. The postauditing design and installation of an intelligent controller by considering the intermittent/interlinked loads are carried out, and the effectiveness of the intelligent controller is ascertained with the energy conservation and the carbon emission reduction of SME. In addition, the climate change mitigation is ensured through the design and deployment of grid-interactive rooftop solar photovoltaic power plant using Solar Pro v4.5 (Photovoltaic System simulation software) with the power analysis, economic analysis and life cycle carbon emission of the proposed plant. The proposed solar photovoltaic power plant ensures energy self-sufficiency and sustainable energy utilization by carbon emission reduction on electricity utilization of SMEs.

“…Audit is recognized as a vital element for process control and continuous improvement (Kalantzis & Revoltella, 2019) and is essential for determining the cost-effective measures that trigger energy efficiency (von Knorring, 2019). Kalantzis & Revoltella (2019: 229) also argued that energy audit (sometimes called energy assessment or energy survey) 'besides being the first step in realizing energy-efficiency opportunities, most likely lead to the adoption of their recommendations …' and '… is a useful tool in overcoming the information barriers and facilitating investments in energyefficiency measures'.…”

“…Find relationships between energy systems, correlations with demands (peak or minimum), leakage, hydrodynamic pressure as well as unusual energy consumption patterns. Bear in mind that the relative importance of the energy cost in the production is among the main drivers of the decisions of top management and that energy efficiency opportunities stand for investments that are financially sustainable and require limited capital spending compared to other core-business investments (Kalantzis & Revoltella, 2019).…”

An integrated procedure has been designed to identify and rank the opportunity for energy efficiency in water supply systems (WSS). The main objective is to help WSS managers to identify key issues to be treated as nonconformity and develop a program for continual improvement of energy efficiency. The procedure was built in collaboration with practitioners and implemented in a company. One of the concerns during the development of the procedure was to provide companies with a fast and user-friendly tool. Complementarily, it also complies with International Organization for Standardization (ISO) and European Committee for Standardization (CEN) standards, and is of great relevance for any company of the sector of water utility. Recommendations for enhancing the energy management in WSS are also addressed in the audit procedure. The findings derived from the evaluation of the state-of-the-art and applications have led to the identification of key issues for energy saving. The success of energy management programs will be based on energy audit and on the top managements' engagement, workers' attitude and qualification, and the financial resources available.

“…Additionally, the 2019 United Nations Climate Change Conference stated that the global building sector and construction industry account for nearly 40% of the total carbon emissions (Ma et al 2020). It is therefore crucial to make some efforts to mitigate climate change and to limit the global increase in temperature to less than 2°C, in line with the recent Paris Agreement, in the area of energy efficiency (Kalantzis and Revoltella 2019). The Intergovernmental Panel on Climate Change (IPCC) reports that governments worldwide have mobilized to decrease carbon emissions in the forthcoming decades (Chen et al 2020).…”

An energy audit was realized for a building group located on a university campus to measure the environmental sustainability and efficient usage of natural resources. As a result of energy audit, exterior insulation and double-glazing application were came to the front for energy-saving options. Although energy audit provides energy-saving options as output, it is not enough to provide information about how environmental impacts will change if the defined options are used. To determine the improvements in terms of environmental indicators, these options were assessed with life cycle assessment (LCA). LCA was realized for 50 years life span for 1 m 3 of the building. CML-IA method was used to conduct LCA analyses. Ecovalue08 was applied as a monetary weighting method since the used CML-IA method has no weighting function. Results show that there are significant improvements (> 5%) on ADP ff (11-12.5%) and GWP100 (8.5-9.7%) impacts provided by both of the energy-saving options. Additionally, double glazing would provide a 10.5% improvement on ODP. On the other hand, the exterior insulation application would increase the ODP value of EB by 34%. The impact category of GWP100 is found as the most dominant impact according to Ecovalue08. The ranking of the other impact categories from higher to lower value is HTP, ADP ff , and AP.
