What is Energy Audit?

Energy Audit is the key to a systematic approach for decision-making in the area of energy management. It attempts to balance the total energy management. It attempts to balance the total energy inputs with its use,and serves to identify all the streams in a facility. It attempts to balance the total energy inputs with its use, and serves to identify the entire stream in a facility. It quantifies energy usage according to its discrete functions.Industrial energy audit is an effective tool in defining and pursuing comprehensive energy management program.

Energy Audit Methodology

Energy Audit Study was divided in following four steps


  •  Historical Data Analysis:

The historical data collection and analysis involves establishment of energy consumption pattern to locate base line of energy consumption and its variation with change in production volumes. This step involves finding out existing Avg. Specific Energy Consumption.

Types of Energy Audit

Preliminary Energy Audit

The Preliminary Energy Audit focuses on the major energy suppliers and demands usually accounting for approximately 70% of total energy. It is essentially a preliminary data gathering and analysis effort. It uses only available data and is completed with limited diagnostic instruments.

What are the procedures involved in Energy Audit?

1. Preparation for energy audit

  • ​Defining the audit criteria                     

  •  Defining the audit scope

  • Selection of energy audit team

  • Making an audit plan

  • Preparing an audit checklist

  • Conducting the initial walk-through visit

  • Collecting energy bills and available data and information

  • Conducting the preliminary analysis


Increasingly in the last several decades, industrial energy audits have exploded as the demand to lower increasingly expensive energy costs and move towards a sustainable future have made energy audits greatly important. Their importance is magnified since energy spending is a major expense to industrial companies (energy spending accounts for ~ 20% of the average manufacturer's expenses). This growing trend should only continue as energy costs continue to rise.Here are some benefits conducting audit.
