Building Energy Performance Index = Consumption (kWh) / Area (sqm)

9

• 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
