Investigation Phase

Implementation Phase

Hand-Off

Planning Phase

Ongoing Cx

Development of Existing Building Commissioning goals, facility requirements, and a commissioning plan.

Field inspections, data gathering, testing and analysis to accurately assess system performance and identify improvement opportunities.

Desired facility improvements are completed and the results and performance are verified.

Systematic transition from a commissioning activity and the commissioning team to standard operating practice and the operations and maintenance team.

Implementation of systems and tools to support persistence benefits and continuous performance improvement over time.

Deliverables from the EBCx Project


The single most important sustainable and energy saving measure you can provide to

improve the life of your building is….TRAINING YOUR BUILDING STAFF!

Training: YES YOU MUST!


Determine Level of Involvement – Who in your organization needs training

Focused training should be on: – Associated FIMs implemented– System optimization techniques– Strategies for persistence and continuous

improvement– Updated maintenance methods and procedures

Training


Commissioning Providers should:• Deliver curriculum and activities for the training

– Interactivity is a must!• Work with you to schedule the right audiences

– Contractors– Building Ops personnel– Manufacturers/Vendors– Management (yes, they need training too)

• Work with you on location logistics– Audio / Visual equipment– Space requirements– Scheduling– Ongoing maintenance during training

Training

Training

• Document the training– Consider contracting with a videographer

• Provide lessons for follow-up• Electronic file storage – ease of finding– Manufacturer literature library

• “Refresher” training for existing employees• Continuous improvement skills training• Create plan for future employees

Consider post-training needs:


Ongoing Commissioning: Optimizing Operations

• Implement Persistence Strategies with the BAS

• Consider AFDD Tools• Implement Re-Cx Process• Baseline Monitoring

OGCx Process – What is Ongoing Cx?

Why Ongoing Cx?• Building Systems Deteriorate • Control Systems Deviate• Equipment Performance Degrades


Ongoing Cx Goals• Identify issues early, resolve them quickly• Increase productivity• Condition-based maintenance vs.

schedule-based

Ongoing Commissioning: Optimizing Operations


Specialized Skill Sets:• MEP field experience• Communications, especially verbal

for interviews• Ability to interact equally with all

levels of personnel• Proven EBCx experience• Commissioning certification

Owner’s Selection Process:• Use Qualifications-Based Selection

(QBS) – not low bid!
