Retro-commissioning (RCx) is one of the key initiatives stated in the Energy Saving Plan for Hong Kong’s Built Environment 2015~2025+ published by the HKSAR Government for the promotion of energy saving in existing buildings. In order to encourage the implementation of RCx in building industry, the Hong Kong Green Building Council (HKGBC) launched the RCx Training and Registration Scheme (the Scheme) in 2019 with support from the Electrical and Mechanical Services Department (EMSD) and other professional institutions, namely Association of Energy Engineers (AEE) Hong Kong Chapter, American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Hong Kong Chapter, Building Services Operation and Maintenance Executives Society (BSOMES), Chartered Institution of Building Services Engineers (CIBSE) Hong Kong Region, Energy Institute (EI) Hong Kong Branch, Hong Kong Association of Energy Engineers (HKAEE), and Hong Kong Institution of Engineers (HKIE) - Building Services Division.

The Scheme aims to provide comprehensive and systematic training to build up the capacity of industry practitioners for the implementation of RCx. Candidates who fulfil the registration requirements can register as RCx Practitioners/ RCx Professionals/ RCx Services Providers, to support the industry in the transition to knowledge-based energy management and taking steps towards the realisation of carbon neutrality target in 2050.

"RCx is a systematic process to periodically check an existing building’s performance to identify operational improvements that can save energy and in-turn lower energy bills and improve indoor environment." – Technical Guidelines on RCx (EMSD)
