Owners Project Requirements Workshops

• Small groups to work out concepts

14
Owners Project Requirements

• The commissioning team is responsible
• OPR gets documented.
• OPR is a Focus
• OM, Efficiency, Easy of Maint., Functional
  needs.
• Address HVAC, Lighting, Indoor Environment

15
Commissioning Plan

• The commissioning plan must contain
• Overview goals
• Project information
• Systems to be commissioned
• Teams roles protocol
• Describe Deliverables
• List Key Milestones and schedule.

16
What Systems does LEED require Commission?

• Systems and Assemblies having to do with
  operational efficiencies
• HVAC Systems
• Building Automation
• Lighting Controls
• Domestic Heating
• Renewable Energy

17
Commissioning Specifications

• Contract Divisions 1, 15 and 16

18
Written Test Procedures

• Objective Must include the following
• Verify systems installed.
• Performs as Specified

CxA Writes the Test Procedures
19
Prefunctional Checklists (PFCs)
20
Installation Verification
Focus is OM
21
Prefunctional Check List

22
Master Deficiency List
23
Verify System Performance

• Functional Testing of Systems
• Observe Startup Activities
• Functionally Test Equipment and Systems

24
Functional Performance Tests (FPT)
25
Final Commissioning Report

• Must be presented to the owner within reasonable
  time and must include
• Executive summary
• Testing results
• Deficiency List and History
• Outstanding Issues
• BOD review.

Issues Lessons Learned

• General
• Commissioning is Part of the Design Team
• Contractors understand the commissioning TEAMs
  Role
• Energy Efficient Systems
• Controls Become Complex and increase Risks
• Technology is beyond Contractor Experience
• Coordination of interposing systems is critical
• Control Systems
• Integration is coordinated
• Schematic diagrams, Sequence of control and point
  lists are necessary
• Details of BMS get input from owner
• Owner Training
• Video tape or not?
• Meeting with Staff to discuss needs
• Detailed Description in Spec of OM needs.
• Systems Manual training

36
Case Study

• Community College Bldg.
• Classroom Laboratories
• MEP Commissioning
• Started Late in Construction Phase
• Issues
• Integrate Phoenix Fume with ALC controls
• System Balance
• Unoccupied Mode Operation
• Success
• teamwork
