Outline
1. Approaches to identifying and quantifying co-
benefits of energy efficiency
2. Local business experiences
3. Harnessing the bigger picture
‘Evidencing the role energy efficiency improvements can play in other types of modernisationprojects might help raise industry interest in exploring available technologies, methodologies or measures.’

Energy efficiency co-benefits
– just to name a few
Improved energy
efficiency
Increased productivity
Improved product quality
Energy security
Reduced maintenance
costs and frequency
Water and materials savings
Co-benefits can be 2.5 times value of energy efficiency

Examples
Estimated 30% increase in productivity of blast freezing operations due to improved operation of the compressors and condensers.
“The new steam traps have improved the consistency of the steam throughput to the ironer bed, and as such improved its efficiency and the end product of our linen. It has also helped us boost our preventative maintenance scheme”.

Insights and conclusion
• Consideration of co-benefits strengthens the case for
energy efficiency
• Can build support across the businesses, including sharing
results with employees
• External energy efficiency experts have an important role in
helping businesses identify and quantify co-benefits
• Use of consistent metrics will assist program evaluation
and make the case for energy efficiency
