The document discusses 7 habits of highly effective energy managers. It notes that fans and pumps are often oversized leading to inefficiency. Compressed air is very expensive to use compared to electric motors. Lighting systems should use sensors and controls to save energy by turning off unoccupied areas. Low hanging fruit like air leaks or poor maintenance always seem to return and require continual management. Production needs sometimes conflict with energy efficiency efforts but energy management provides opportunities. Regular sub-metering and measuring energy use allows managers to focus on significant energy uses and track performance metrics like energy intensity per unit of production.

1. 7 Habits of Highly
Effective Energy
Managers
Rick Marsh
Director, Industrial EE Network

2. 2
Engineers Design for “Just in
Case” not Energy Efficiency
• Fans & Pumps are usually oversized to
consider worse case scenarios.
• Furnaces designed for peak product flow but.

3. 3
Air is FREE!
(Compressed Air is Very Expensive)
• Compared to electric motors, the work that is
conducted by compressed air is 7 times more
expensive.
• Poor management of air supply can yield
inefficiencies for costs and also in meeting demand
events.
• Inappropriate uses and leaks are BIG opportunities

4. 4
Motel 6 Got it Wrong –
Don’t Leave the Lights On
• Changing bulbs is a good first step
• All light is not created equal
• Sensors and controls
– Occupancy sensors
– Daylighting
– Timers

5. 5
Reality is Somewhere Between our
Expectations & Total Chaos
• Few industrial operations are truly 24/7
• Compressor sequencing & controls can adversely
affect energy efficiency

6. 6
Low Hanging Fruit Always
Seems to Grow Back
• Air & steam leaks
• HVAC efficiency losses
• results of poor maintenance
• equipment degradation
= need for a continual management process.

7. 7
Production Needs vs. EE
(Can’t We Just All Get Along!)
• Perceived needs
• Refusing to change anything that may cause a
production issue often conflicts with energy
reduction
• Energy Management
= Opportunity

8. 8
Metering
You Can’t Reduce What You Don’t
Measure, and You Can’t Measure What You
Don’t Meter
• Sub-metering helps to align energy consumption
with significant energy uses allowing for
concentration of effort.
• Measuring energy performance should be
calculated as a basis of production (energy
intensity) without consideration for rate changes
– MMBtu/unit production
