Testing Adjusting & Balancing Services
Today's buildings are complex - they have highly interdependent systems with sophisticated controls, and even small operational problems can have large impact on the performance of the overall system. Equipment and systems must work together effectively and efficiently to meet the building owners operating requirements. No matter how carefully a building is designed, if the systems, equipment, and materials are not installed and operating as intended, the building will not perform well. Similarly, the systems age and performance begin to degrade over time. Building uses can also change - occupants move, spaces are reconfigured, new equipment is added - making previous systems and settings ineffective.
Testing, adjusting, and balancing (TAB) is a quality assurance process that looks at how and why a building's systems are operated and maintained, and then identifies ways to improve overall building performance. TAB addresses root causes to systematically ensure that building systems operate efficiently, effectively and reliably, and ensures that facility improvement measures continue to persist over time.
The term commissioning comes from shipbuilding. A commissioned ship is one deemed ready for service. Before being awarded this title, however, a ship must pass several milestones. Equipment is installed and tested, problems are identified and corrected and the prospective crew is extensively trained. A commissioned ship is one whose materials, systems and staff have successfully completed a thorough quality assurance process.
Building commissioning takes the same approach to new buildings or systems. When a building is commissioned, it undergoes an intensive quality assurance process that begins during design and continues through construction, occupancy and operations. Commissioning a new building, or a new system within an existing building, ensures operation as the owner originally intended and the building operators are adequately trained to reliably maintain all systems and equipment. The main component of commissioning involves testing, adjusting and balancing.
