OUTLINE WHAT IS COMMISSSIONING?
IS THERE A NEED FOR COMMISSIONING?
VALUE OF COMMISSIONING
COMMISSSIONING SCOPE- NEW CONSTRUCTION
COMMISSSIONING AND LEED
COMMISSIONING IS A QUALITY ASSURANCE PROCESS
A coordination process that optimizes building performance (occupant comfort, reliability, energy efficiency)
Articulating/verifying energy-related design intent Construction observation and warranty enforcement Controlling first cost Training the owners operational staff Enhancing safety and risk management Creating more cohesion among team members
ABSOLUTELY
All buildings are “Complex Machines and the mechanical systems in particular serve as the heart”
Many problems are hidden by a energy-wasting process (e.g., a stuck economizer is compensated for by extended chiller operation)
The process of designing, building, documenting, and operating buildings has become increasingly
fragmented Design and operation often is done without regard to system interactions [moisture problems as evidence] Energy Efficient technologies tend to be more sophisticated (error prone?) than traditional
techniques
For Building Owners/Occupants • Comfort/productivity; continuous occupancy • Warranty enforcement • Reduced construction time • Occupant/tenant satisfaction • Longer equipment life • Reduced maintenance and life-cycle costs For Trades • Improved information flow among team members • Reduced call-backs or change orders • Increased likelihood of client satisfaction For CEO, CFO, COO….. • Program success: e.g. customer acceptance • Meeting and maintaining targeted savings
