Low hanging fruit

• Changing out light bulbs or delamping• Retro-commissioning• Changing out a/c units• Old DSM programs like express efficiency

Result: 10 - 15% savings

Let’s compare

Cream skim• Light bulbs

• $50,000 Cost• ROI 40%• 10% energy savings• 0.1% op cost savings

Integrated bundle• HVAC, Controls,

Daylighting, Fenestration• $400,000 Cost + 4%• ROI 15%• 80% energy savings• 15% op cost savings

Over the last fifteen years PE Consulting has engineered over

$1 billion in energy savings

for it’s clients.

My pet peeves

• Designing around first cost• Energy decisions based on Simple Payback• Designing around LEED points• Not mandating performance metrics• Lack of performance metrics• Lack of continuous benchmarking

10

w/o benchmarking

• No idea what your limitations or potential are

• Vendor can sell you anything

“If I added up all the savings these vendors told me I’d get, I would save over 150% of what we consume…”

11

With benchmarks

• Faster decision making• Recognition from management• Stakeholder buy in from all users• Eligible for rebates• EPA Energy Star Portfolio Manager, CBEP• Baseline to judge performance from

12

EPA Energy Star Portfolio Manager

• Benchmarks across the nation, graded on the curve.

• So don’t get TOO excited if you reach 75%

• Grade against your top peers AND your targets.

13

w/o performance monitoring

• Driving by watching (only) the rear view mirror• May take months to spot problems, costing $$$• Leed Platinum NC that wouldn’t even make

LEED Silver EBO&M.

14

With performance monitoring

• Immediate alerts of problems• Prevent (or at least predict) equipment failures

before they happen• Reduce or eliminate comfort calls• Protect your investment• Best Practice Tip - use outside consultant

(at a minimum for setup and validation).
