To expedite low-carbon transformation of Hong Kong and even the world, the HKGBC proactively supports the World Green Building Council (WorldGBC)’s initiatives and closely works with green building councils in other regions. At the ceremony, the HKGBC also announced that the “HKGBC Retrofitting Guidebook” would be released in over 70 regions by local green building councils. It is anticipated that retrofitting concepts can be further promoted around the globe.
Ir Eric PANG Yiu-hung, JP, Director of the Electrical and Mechanical Services, The Government of the HKSAR, said, “Showcasing successful experience and case studies of retrofitting projects, the ‘HKGBC Retrofitting Guidebook’ is an invaluable reference tool for the industry.”
Mr Donald CHOI, JP, Director cum Industry Standards and Practices Committee (ISPC) Chairman of the HKGBC, remarked, “Since 2016, ISPC has been working closely with the Government on the promotion of retro-commissioning (RCx). To further our expertise on enhancing building energy efficiency, our committee has indicated the development of this Retrofitting Guidebook, which captures and provides the retrofitting solutions and case studies for readers to have a comprehensive understanding on retrofitting. We believe that the project can help industry to advance their knowledge in retrofitting. Let’s construct a green society together!”
Ir Dr Cary CHAN, JP, Executive Director of the HKGBC, said, “The objective of this Retrofitting Guidebook is to promote and facilitate the industry to implement retrofitting. This is intended to be a living document which will be updated from time to time, with the latest best practices and technology advancements. To mainstream retrofitting in Hong Kong’s decarbonisation roadmap, the HKGBC will announcement more projects and events in due course such as webinars and conferences, competitions, pilot projects for trying out novel and smart retrofitting technologies. As the Chair of WorldGBC Asia Pacific Regional Network, I’m pleased to see our Guidebook will also be released to the whole world as it signifies Hong Kong’s leading position in driving the development of the sustainable built environment in the global arena.”
Buildings related activities in Hong Kong account for around 90% of total electricity consumption and over 60% of total carbon emissions. In addition, existing buildings take up a very large proportion of local current building stock; it offers massive potential for energy savings. Mainstreaming retrofitting is therefore one of the key focuses of the HKGBC’s target in advancing net zero ambition. The HKGBC Retrofitting Guidebook is a timely publication providing strategies for retrofitting with a view to optimising the performance of existing buildings. It presents various retrofitting options and considerations with case studies for the industry’s reference. Other resources such as available funds in the market are also demonstrated to help facilitating building owners to perform retrofitting works in their buildings.
As introduced by Ir Victor CHEUNG, Director cum Retrofitting Expert Group Convenor of the HKGBC at the ceremony, the Guidebook has presented the retrofitting strategies in 10 key themes, including Heating, Ventilation, Air Conditioning – Water-side and Air-side, Lighting, Electricity Distribution System, Lift & Escalator, Smart Control Systems, Server Room / Data Centre, Carpark, Heating, and Building Envelop. Costs and benefits of the retrofitting strategies are also demonstrated through case studies.
