  1. 1. Retro-Cx Is like Mining for Gold Murray Guy, Integrated Designs
  2. 2. $5000 Retro Investment avoids a $1.8M Air Quality Improvement Project Retro-Cx hits the Mother Load 6 Ounces Sierra County, California
  3. 3. Can Retro-C Save the Planet? “What is that all about?”
  4. 4. BUILDINGS 1/3 of Canada’s Energy Use 50% of extracted materials 25% of our landfill waste 10% of our airborne particulates 40% of our greenhouse gases Reference: A Business Case for Green Buildings in Canada
  5. 5. If the entire stock of existing non-residential buildings in the U.S. were retro-commissioned, as much as $30 billion of energy savings and 340 million tons of CO2 could be avoided annually. (LBL Study) What if we TUNED all non-Residential Buildings?
  6. 6. Should BOMA tell Justin about this?
  7. 7. Energy Saving (Less than 2 Yr Payback) Environmental Quality (Productivity $500 psf) Less Stress (# of Fires to Put Out) Building Renewal Opportunities (POS) Capital Cost Avoidance (Young Offenders) Water Saving (Getting to be a Bigger Issue) Lots of Different Nuggets
  8. 8. I especially like the Less Stress Nugget
  9. 9. Retro-Commissioning must be TOP SECRET Where else can you do you get a low risk >50% return on Investment? WHY isn’t everyone doing it?
  10. 10. • Business Case • No Commitment No Money • No Time What are the Barriers?
  11. 11. Great strides have been made in advancing the knowledge and awareness about commissioning by such groups, as ASHRAE and the Building Commissioning Association, however there are still many barriers to overcome before the commissioning industry gets recognition for being a GREAT investment. The REALITY is that “Commissioning is arguably the Single-Most-Cost Effective strategy for reducing energy costs and green house case emissions in buildings today” Retro-Commissioning
  12. 12. We just Made the Business Case Its up to Stakeholders to make “the Claim”
  13. 13. No Commitment Make the Pitch
  14. 14. No Money Lease? or Finance?
  15. 15. No Time Hire a Retro-Cx Provider
  16. 16. How to Mine the Claim Stage 1 • Benchmark the Facility (MJ/M2) • Compare to other Facilities • Cowboy Math Analysis (Go no Go)
  17. 17. • What is the current Energy Usage? • How does it compare to industry averages? • Cowboy Math • Savings (10% of $5.00 psf) = $.50 • Cost $0.50 psf • Payback 1 Year • Make the Pitch
  18. 18. Determine how big of a Gold Deposit Try the IDI Energy Use Assessment Tool www.i-
  19. 19. • Assemble a Team • Define Project Requirements • Plan, Budget and Funding • Implement, Verify and Repeat How to Mine the Claim Stage 2
  20. 20. Who should be on “the Team” 1.Facilities Manager 2.Cx Manager 3.Tenant or Occupant Rep 4.Building Operator(s) 5.Finance Guy 6.Specialized consultants depending on measures to be taken (Controls trades, balancers, M&E Engineers, etc.)

  22. 22. What Issues? • Critical problems • Occupant complaints • Seasonal problems • Peak loads problems • Environmental quality problems • Safety/Regulatory • Energy Costs above expectation or growing over time • Frequent equipment failures
  23. 23. Collect the Easy Nuggets First • Filters/Belts • Deferred Maintenance (leaks, etc.) • Known broken “stuff” • Balancing • Bad Habits (open windows in winter, space heaters for over- cooling, etc) • Control Setpoint & Sequences
  24. 24. • Are sequences known and documente • Are systems being overridden to resolv • Schedules & Set points • Demand control ventilation • Daylighting Control • Additional Metering No More Half Dead Zombie Controls
  25. 25. Tune the Building then Dig Deeper • Full Building Energy Audit? • Systems Upgrade? • Space Utilization? • Building Renewal?
  26. 26. Lessons Learned Getting Retro-Cx Done • Understanding Owner Requirements is key • Studies and audits are OK, but action needs to be taken and changes need to be sustained
  27. 27. Innovation Place Case Study Make me Money
  28. 28. High Performance Building Program
  29. 29. Re-Commissioning process helped reduce energy use from 900 MJ/m2 to 600 MJ/m2 (30% Reduction) Retro or Re-commissioning can reduce GHG in buildings by 15% to 40%
  30. 30. Energy Performance Innovation Place Energy Use 2,000 2,100 2,200 2,300 2,400 2,500 2,600 2,700 2002 2003 2004 EnergyUse(MJ/m2) Energy Use (MJ/m2) Energy Use Targets Annual Energy Saving: $500,000/yr Savings to Date: $5,000,000
  31. 31. SRC ANALYTICAL LABORATORY Renewal Project
  32. 32. What are the Priorities? 100/10/1 People Production Facilities $500/sq.ft/yr $500/sq.ft $5/sq.ft/yr Operating Cost
  33. 33. Enough Energy Savings to fund a $5M Building Renewal
  34. 34. City of Saskatoon Electrical Operations Center
