ASHRAE Guideline 0 presents best practices for applying whole-building commissioning to facilities. The principles and processes included apply to all phases of new construction and renovation projects and provide a uniform, integrated, and consistent approach to commissioning. ASHRAE Guideline 0 includes the Total Building Commissioning Process (TBCxP) as defined by National Institute of Building Sciences (NIBS) in its Commissioning Process Guideline 0.
This 2019 edition of ASHRAE Guideline 0 updates terminology to reflect an evolving whole-building Commissioning Process (Cx) and harmonizes terminology and its usage with that of ASHRAE/IES Stand-ard 202.
