Retro-commissioning Charter Programme

We provide practical retro-commissioning training to improve the energy efficiency in your building.

About this programme 

Retro-commissioning (RCx) is a cost-effective way to optimise a building’s operational performance without the need to replace existing equipment. It is a relatively low-cost investment with shorter payback periods.

The CLP Retro-Commissioning (RCx) Charter Programme has been popular with customers since it was launched last year. In view of the overwhelming response, we are running an Advanced Training Course for energy management teams with basic RCx knowledge to further upgrade their skills and help businesses achieve low-carbon transformation in a cost-effective way.

Features of the Advanced Training Course:

  • A two-day in-depth theoretical and practical training together with on-site evaluation
  • Comprehensive coverage of technical skills and knowledge, including data analysis, system diagnosis, measurement and verification
  • Qualification as RCx Professional for participants who successfully complete the training course and pass an assessment 


Reduce Consumption & Costs

By implementing RCx, you can identify hidden opportunities to save energy and costs in buildings. Eligible RCx projects will be subsidised by the Eco Building Fund to further help shorten the investment payback period*.

*The subsidy amount is up to 100% of the total project cost, depending on the estimated annual energy saving. 

Equip Your Team with RCx Expertise

A tailored RCx training course with our full sponsorship will be offered to a maximum of three energy management staff nominated from your organisation.

Your organisation can fulfil the corporate and social responsibility and take part in regular RCx promotional activities.
