  • 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.
  • Doug’s loading order Results: 90 - 100% savings
  • 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
  • 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…”
  • 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
  • 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.
  • 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.
  • 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).
  • How to Fund Energy Efficiency Utility Spend Maintenance & Operations Budget Capital Budget Savings Savings Savings Grants, Rebates and Tax Credits
  • What to do
    • Benchmark
    • Master Plan
    • Audit
    • Design and Retrofit
    • Commission and Certify
