- An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building.
- It may include a process or system to reduce the amount of energy input into the system without negatively affecting the output.
- The energy audit provides the vital information base for the overall energy conservation program covering essentially energy utilization analysis and evaluation of energy conservation measures.
- It aims at identifying the quality and cost of various energy inputs.
- The audit team should comprise of employees from production, quality control, research and development lab, pollution control operations, technical staff for monitoring and analysis of water samples and environment.
- The team may have 4 to 8 members depending on the size and complexity of the facility to be audited.
- Accordingly, an environmental audit is typically undertaken in three phases:
- Pre-audit phase
- On-site audit phase
- Post-audit phase
Activities of Pre-audit phase
- Develop an Audit plan
- Prepare Pre-audit questionnaire
- Review background information and identify the areas of considerations
- Review operational information
- Develop audit team
- Develop visit program
- Conduct initial site questionnaire and audit protocols
