Technical Energy Audit
An energy audit comprises a detailed analysis of the energy performance of an organization, equipment, system(s) or process (es). It is based on appropriate measurement and observation of energy use, energy efficiency and consumption. Energy audits are planned and conducted as part of the identifica
tion and prioritization of opportunities to improve energy performance, reduce energy waste and obtain related environmental benefits. Audit outputs include information on current use and performance and they provide ranked recommendations for improvement in terms of energy performance and financial benefits.
An energy audit can support an energy review and can facilitate monitoring, measurement and analysis as described in ISO 50001, or it can be used independently.
The process flow diagram of an energy audit is presented here which comprises of several steps,
- Start-up meeting to brief all parties involved about the process, schedule and methodology
- Measurement plan
- Site visit
- Performing of additional measurements
- Collecting data to determine the total energy consumption, the energy consumption of relevant consumers and energy performance indicators
- Analysis of the existing energy performance
- Development of possible energy-saving actions
- Preparation of an energy audit report; Closing meeting
An energy Audit can be performed in different levels from a walk through audit to comprehensive audit, i.e type 3 audit according to ISO 50002:2014
