Purpose This paper aims to review standards on or related to retro-commissioning (RCx) and policy measures that are applicable for fostering wider adoption of RCx in existing buildings. In addition to engendering broader polemic debate to address the respective gap in the prevailing body of green building knowledge, the research outcome signposts future directions of works required for developing the needed standard and policy.Design/methodology/approach Following an integrative review approach, RCx-related literature, statutes, publications of public and professional organizations and standards published by institutions including the International Organization for Standardization and other peer organizations in the USA, the UK, Canada and Germany were reviewed.Findings Cities such as Hong Kong and New York in the world’s two largest economies (China and the USA) have been proactive in the pursuit of energy-efficient buildings. Various US cities have imposed statutory requirements on RCx. The need for an international standard on RCx and a bespoke policy for driving the uptake of RCx was also identified.Research limitations/implications Drawn from the research includes the need for further policy research studies to direct how an appropriate policy could be established to engender wider RCx adoption internationally.Practical implications Practical implications center on the identified need to develop a specific standard of RCx works. Making such a standard available to facilities management practitioners is pivotal to realizing the goal of green buildings.Originality/value This study provides new insights, especially the future directions in developing bespoke RCx standards and policy for greening the existing buildings.
