UNIDO ENERGY AUDIT INSTRUMENTS
What has been achieved in the UNIDO Program
Vietnamese Food Company reduced their natural
gas consumption by 12% in the first year of
implementing an EnMS.
Philippines steel company improved energy
performance of its furnace by 5% by simple
operational control measures.
Indonesian paper company improved overall energy
performance in the first 6 months by 7%. Focusing at
low cost measures. Overall Payback 0.5 year
Thailand steel company saved 11GWh of fuel by
changing process set points. The savings paid for a
plant upgrade which delivered a further 23 GWh of
savings with a simple payback of 7 months
What is the process of EnMS? It Works Using Six Key Concepts
1. Commitment
Roles and Responsibilities
2. Significant Energy Users (SEUs)
3. Energy Performance Indicators (EnPIs)
4. Opportunities List
5. Operational Control
6. Review

What can an EnMS achieve?
Ad-hoc (Project Based) Approach
Structured Approach (EnMS system)
Based on improvement in energy intensity.

2007 1% 7%
2008 4.7% 6%
2009 1% 5%
2010 -0.3% 7%
What can be achieved?
What does EnMS offer to industries, consumers and users?
Reduced operating costs
Reduced exposure to rising energy costs
Improved reliability and productivity
Reduced environmental impact
Improved corporate image
Alignment with ISO 50001
Initially based on low cost
improvements
What sort of actions will we take?
Operation and maintenance initially
• Fix leaks
• Fix insulation
• Switch off
• Run optimum equipment
• Optimum settings
• Check controls
• Training
• Maintain improvements
Energy System Optimization:
Maximizing Energy Savings
Component v System Approach
Component approach involves
• segregating components and analyzing in isolation
• possibly as a result of education by particular technology sales engineer, e.g. variable speed drive, steam trap, etc.
System approach involves
• looking at how the whole group functions together
• how one change can impact on system performance
• Requires more knowledge of the system and its interactions
2 to 5 % efficiency gains for individual components versus
15 to 30% potential efficiency gains through system optimization
