Retro-Commissioning Resource Centre
2026-06-02
Even though newly completed buildings undergo commissioning for various building services installations prior to operation, factors such as alterations in space utilization and shifts in occupant behavior over time often create a gap between design intent and actual operation. This frequently causes building energy performance to fall short of expectations. Consequently, retro-commissioning (RCx) can uncover substantial energy-saving potential within these buildings.
To support this, the Electrical and Mechanical Services Department (EMSD) has launched a new webpage that consolidates comprehensive RCx resources, including technical guidelines, training courses, and case studies. This one-stop platform enables both the general public and industry professionals to access the latest RCx updates and enhance building energy efficiency.
