• Sub-metering in the facility revealed the biggest
opportunity: (need name of opportunity)
• Heat transfer problems
• Low chiller COP
• 24/7 operation
• Ineffective staging
Example 1: Analyze the Biggest Priority
10
Example 1 Continued: Tackling the Problem
11
• Package as many problems together as possible
• Work with manufacturers and contractors on-site
Example 1 Continued: Results
12
• 5% reduction due to:
• Overhaul of wiring
• Instrumentation upgrades
• Sequence of control changes
• Cleaning coils and fixing AHU problems
• 3% reduction due to:
• 3 way valve replacement
• VFD installation on secondary chiller pumps
• Expect 15% savings from new chillers
Example 2: Problem Brought to Me
13
• Lights were too bright in the IT department
• Building coordinator took lead, I supported
• Actions taken:
• double T8 replaced with
single T5 with built-in
aluminum reflectors
Example 2: Results
14
• More comfortable space
• More energy efficient
• Less maintenance
• Repeatable process understood by in-house
staff
• Rolled out across the rest of Priority 1 and 2
space without my involvement
