Building Commissioning

Building Commissioning (Cx)

A quality-based method that is adopted by an Owner to achieve successful construction projects

Building Commissioning is the professional practice that ensures buildings are delivered according to the Owner's Project Requirements (OPR). Buildings that are properly commissioned typically have fewer change orders, tend to be more energy efficient, and have lower operation and maintenance cost. The documentation of the commissioning process provides the foundation for correctly benchmarking the baseline energy consumption of the facility.

The Commissioning Process begins at project inception (during the Pre-Design Phase) and continues for the life of the facility (through the Occupancy and Operations Phase). The Commissioning Process includes specific tasks to be conducted during each phase in order to verify that design, construction, and training meet the Owner’s Project Requirements.

The Commissioning Process is a quality-based method that is adopted by an Owner to achieve successful construction projects. It is not an additional layer of construction or project management. In fact, its purpose is to reduce the cost of delivering construction projects and increase value to owners, occupants, and users.

Commissioning Goals:

  • Deliver buildings and construction projects that meet the owner's project requirements.
  • Prevent or eliminate problems inexpensively through proactive quality techniques.
  • Verify systems are installed and working correctly and benchmark that correct operation.
  • Lower overall first costs and life-cycle costs for the owner.
  • Provide documentation and records on the design, construction, and testing to facilitate operation and maintenance of the facility.
  • Implement trend logs, automated and semi-automated Cx tools to enable O&M staff ongoing Cx.
  • Maintain facility performance for the building's entire life cycle.

GBDCx provide commissioning Engineers/Managers for building commissioning services as per ASHRAE Standard. We help Owner to ensure the project meet OPR.

Existing Building Commissioning (EBCx)

Retro-Commissioning, Re-Commissioning or Ongoing commissioning

Existing Building Commissioning is a systematic process for investigating, analyzing, and optimizing the performance of building systems through the identification and implementation of low/no cost and capital intensive Facility Improvement Measures and ensuring their continued performance. The Existing Building Commissioning process assists in making the building systems perform interactively to meet the Current Facility Requirements and provides the tools to support the continuous improvement of system performance over time.
