In our role as Energy Auditor, an energy audit is a procedure that involves identifying every energy flow within the system and quantifying energy use based on a discrete function. It seeks to achieve an energy balance between input and output. Energy audits assist with pollution control, cost optimization, and other safety-related issues, as well as helping to improve the system's operating and maintenance procedures. An organization can protect itself from changes in the availability of energy costs by conducting an energy audit. Additionally, it facilitates the selection of a suitable energy mix, ensures energy supply reliability, and promotes the use of more advanced technology and equipment for energy conservation. In the initial phase, it is just a data collection. Only the available data and a few diagnostic tools are used for the audit.
