Energy Efficiency Measures
BUILDING COMMISSIONING
Commissioning a building, either when new or after a major retrofit,
is the process of testing all elements of a building’s energy and mechanical
systems to ensure that they are adjusted properly and functioning optimally.
Suppliers of services and equipment should be tasked with providing
commissioning services as a condition of the purchase agreements. One important
element of the commissioning process is to ensure that the building’s
maintenance staff is fully trained to understand, test, and maintain the
equipment, including the consequences of interaction between systems.
Continuous commissioning is a maintenance function through which all
critical elements of a building’s energy and mechanical systems are routinely
monitored for proper adjustment and functioning. The idea is to enhance
preventative maintenance chores and solve difficulties before they become real
problems. Key elements of a successful continuous commissioning process are the
output of the energy management system, regularly inspected energy bills, and a
knowledgeable and dedicated maintenance staff. For additional information, visit

The Energy Systems Laboratory at Texas A&M University, which coined the term
“continuous commissioning,?has been involved in continuous commissioning
projects in Texas that now save well over $20 million per year. Paybacks from
such projects are routinely less than three years; many are shorter even than
that. According to the National Strategy for Building Commissioning, a thorough
commissioning process will confirm that building systems and equipment are
operating properly, allowing the owner to realize the benefits of:
- Improved building system control;
- Increased energy efficiency;
- Improved building equipment performance;
- Improved indoor air quality, occupant comfort, and productivity;
- Decreased potential for owner liability; and
- Reduced operation and maintenance costs.
