Title: How to Have a Successful Retrocommissioning Project


1
How to Have a Successful Retrocommissioning
Project
Successful Retrocommissioning
  • Karl Stum, PE
  • Portland Energy Conservation Inc. (PECI)

2
What We Will Cover--
  • Definitions
  • Planning phase activities
  • Investigation and implementation phases
  • Hand-off phase

3
Retrocommissioning
  • Existing equipment
  • Seeks low-cost operational improvements
  • Likely wont get done with a conventional
    performance contract

4
Phases of the Process
  • Planning
  • Investigation
  • Implementation
  • Hand-off

5
Building Selection
  • Enthusiastic facility staff
  • Facility staff have time
  • Owner has money to put into project
  • High energy users?

6
Objectives
  • System verification (RCx)
  • Energy savings
  • Problem areas
  • What systems?
  • HVAC
  • Lighting
  • Controls
  • Specialty

7
System Verification
  • Systematic testing of systems
  • Like new construction testing
  • Report card

8
Energy Savings
  • Focus on big energy using equipment
  • Comfort?
  • IAQ?
  • Capital improvements?
  • Energy-only may not be compatible with std. RCx

9
Problems Areas
  • Comfort
  • System control
  • IAQ

10
Satisfy All Stakeholders
11
Satisfy All Stakeholders
  • Owner
  • Utility
  • Energy manager
  • Facility manager
  • Facility engineer/operator

12
Types of Implementation
  • By Whom
  • All by owner
  • CP oversees
  • CP implements
  • When
  • Along the way
  • After full finding report

13
Selecting a Provider
  • Done it before
  • Experienced with your issues
  • TAB
  • Design
  • Equipment
  • Energy
  • Troubleshooting
  • Controls
  • References
  • Approach

Trust me.
14
Scope of Work
  • Dont promise the farm
  • Be explicit
  • Consider phasing the project--investigation /
    implementation

15
Scope of Work
  • All but insist that you do some implementation or
    follow-up
  • Allow enough time for implementation
  • Leave documentation for facility staff

16
Expectations
  • Understand them
  • Manage them
  • Document

17
Budgeting
  • Be realistic
  • Many projects are scoped to a budget rather
    thanthe opposite
  • Typical 100k - 500k sf, typical energy projects
  • 20k-50k for investigation, and
  • 10k-30k for implementation of findings

18
Cx Plan
  • Clear
  • Complete
  • Include a schedule

19
INVESTIGATION IMPLEMENTATION PHASE
20
Kick-Off Meeting
  • Team building
  • Communicate objectives
  • Communicate process
  • Clear up questions

21
Staff Issues
  • Managers support staff
  • Time
  • Appropriate staff resources
  • Allocate budget to implement
  • Commissioner respect staff
  • Dont take their whole day
  • Dont make staff look bad (call a spade a heart?
    Or is the glass half empty or half full?)

22
Communication
  • Document all scope directives and changes
  • Keep parties informed of progress
  • Meet to go over findings

23
Communication
  • Provide clear findings and recommendations
  • Make report accessible--use summary tables

24
Remaining on Track
  • Remember to please all stakeholders
  • Revisit your budget often
  • Dont go too deep in one area
  • Leave enough for analysis and implementation

25
Implementation
  • Consider interactions of recommendations
  • Plan for verification, if required
  • Identify that all players are satisfied
  • Document

26
HAND-OFF PHASE
  • Provide a clear / accessible report
  • Leave staff with guidance in writing
  • Implementation plan
  • Optimum operating parameters
  • Updated sequences of control
  • Recommissioning plan
  • Energy accounting plan
