Building Commissioning
Building commissioning is the practice of having a third party verify the performance of a new building's systems. Commissioning can also be used in restoring older buildings. This is referred to as retro-commissioning.
A trained professional systematically evaluates a building to ensure that building systems perform efficiently and that building operators are properly trained in operation and maintenance procedures. In this sense, building commissioning recognizes the human element of energy efficiency in buildings. Energy-efficient features and equipment can be undermined by improper use. Commissioning activities begin in the planning stage of new construction or retrofit, and continue throughout the project and after completion.
Commissioning is most often used in schools, hospitals, industry, and government.
The cost of building commissioning varies, depending on the size and complexity of the project. The Oregon Department of Energy estimates building commissioning to cost about 1% of the total cost of the project; operational costs range from 8% to 20% lower than for noncommissioned buildings. The additional upfront costs can result in significant savings from reduced utility bills, decreased maintenance costs, and increased worker comfort and productivity.
Argument for Building Commissioning
- Can result in substantial savings and improved comfort in the long run.
Argument against Building Commissioning
- Can result in additional upfront costs.
The Oak Ridge National Laboratory's Building Technology Center has more information on building commissioning.
The Oregon Department of Energy has more information on building commissioning including case studies on public buildings.
Texas A&M University's Energy Systems Laboratory is another good source of information on building commissioning and related issues.
