Commissioning CONCEPT

Commissioning is a planned and integrated systematic process to ensure through documented verification that all building equipment/systems operate according to design intent. The commissioning process requires a collaborative team effort and can begin in the pre-design phase and continue through all phases of construction, initial occupancy, training of O&M staff, preventive maintenance program review and warranty period.

Benefits from commissioning can be achieved no matter when the process starts. With a potential savings of up to 20% in owning and operating cost, the earlier the commissioning process begins the greater the benefits.

Commissioning gives the building owner/operator assurance of a correctly operating building at completion of construction. The owner/operator can be confident in continued correct operation because of equipment/system documentation and staff training.

what’s the benefit

Cost savings of commissioned projects:

Reduction in design problems

Reduction in design problemsReduced project delays

Reduced change orders

Correct start-up requirements

Shorten building turnover period

Reduced post occupancy corrective work

Improved quality of indoor working environment

Increased building system/equipment reliability and maintainability

Reduced energy and operating cost

Increased value as a result of better quality construction




immediate results

Deficiencies most often discovered by commissioning new and existing buildings:

Incorrect heating and cooling sequence of operation

Lack of building control strategies for optimum comfort and efficient operation

Incorrect equipment installation

Malfunctioning economizer (free cooling) systems

Short cycling of HVAC equipment leading to premature failures

Missing specified and paid for equipment

O&M manuals not specific to installed equipment

Problems resulting from lack of training for staff maintenance personnel

Lack of documentation for equipment/systems problems during warranty period
