COMMISSSIONING AND LEED

WHAT IS COMMISSIONING?

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

IS THERE A NEED FOR COMMISSIONING?

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
