Building Commissioning is the professional practice that ensures buildings are designed, constructed and operated according to the Owner’s Project Requirements (OPR). Buildings that are properly commissioned typically have fewer during construction surprises, tend to be more energy efficient, and have lower operation and maintenance cost. The commissioning process provides the foundation for desired and controlled energy consumption of the facility.
It is important to start the commissioning process as early as possible and in the pre-design phase. The early involvement is critical for the timely and useful development of the Owner’s Project Requirements (OPR), and its effect on the subsequent design team Basis of Design (BOD), preparation of the Commissioning Plan, and the beginning of the Operations & Maintenance (O&M) Systems Manual. If these tasks are left until later in the process, then it will have to be arranged to match the design and construction and it loses the values of dialog between all parties, cost and life cycle management and all other benefits.
The systems to be commissioned commonly include the Heating, Ventilating, and Air Conditioning systems or HVAC, Service or Domestic Hot Water Heating systems, and the Lighting Controls. In addition to these systems, any other energy using system can also be commissioned such as solar Power or Water Heating systems if desired.
