What is commissioning?
Building Commissioning is a process for verifying and documenting that the performance of buildings, systems, and subassemblies meets defined objectives and criteria. Commissioning is a quality-oriented process which sets out a framework for achieving the building owner’s objectives.
A commissioning effort can be integrated into the building acquisition process for a new construction effort or it can be undertaken as a stand alone project to improve the performance of existing buildings.
What are the benefits of building commissioning?
1. A 2009 study by Lawrence Berkeley National Laboratory found that commissioning services save the building owner money.
- Commissioning reduces energy costs by 16% for new construction and 13% for existing buildings.
- The median annual cost savings resulting from commissioning was found to be $0.29/ft2 each year for existing buildings and 0.18/ft2 each year for new construction.
- The payback period for commissioning costs was found to be 4.2 years for existing buildings and 1.1 years for new construction.
2. According to the University of Wisconsin, the commissioning process:
- Reduces lifetime owning, operations, and occupancy cost of the building.
- Reduces the first delivery cost of the building.
- Provides clear documentation and training which can be used to better maintain buildings.
3. Commissioning creates a focus on verifying that the building owner’s requirements have been met throughout the planning and construction phases so that more of the available project funds can be used for owner’s, user’s, and occupant’s needs rather than towards unanticipated change orders, rework, or callbacks.
