ACG is the world’s largest network of certified independent 3rd party commissioning agents and is ANSI accredited and recognized by the U.S. Department of Energy’s Better Buildings Program. ACG also publishes its widely cited ACG Building Systems Commissioning Guideline, which is being updated in 2022. Government officials, code authorities, and institutional building owners may request complimentary access to the ACG Guideline by contacting ACG Headquarters at firstname.lastname@example.org.

Commissioning is a quality control-based process that helps to ensure that buildings are designed, constructed and operated in accordance with the Owner's Project Requirements (OPR). In addition to mechanical, electrical and plumbing (MEP) systems, commissioning of the building envelope and other systems is becoming increasingly common. Ideally, the commissioning agent (CxA) is an independent 3rd party contracted directly by the building owner or owner’s representative.
CODE AND GREEN BUILDING REQUIREMENTS
Commissioning is required by model building codes such as the International Energy Conservation Code (IECC) and the International Green Construction Code (IgCC) and increasing numbers of states and municipalities are adopting and enhancing the requirement. Commissioning is also a requirement of green building certification programs like the U.S. Green Building Council's LEED® (Leadership in Energy and Environmental Design) rating systems.
EXISTING BUILDING COMMISSIONING
Historically known as “Retro-Commissioning” and “Re-Commissioning”, Existing Building Commissioning applies the principles of commissioning to existing buildings that may or may not have been commissioned previously. The process is used to re-establish the original design intent and confirm any modifications that may have been made over time. Existing Building Commissioning is an especially useful tool for troubleshooting building operational and thermal comfort issues, frequently resulting in lowered energy consumption and more satisfied building occupants.
