The Buildings Energy Efficiency (Amendment) Bill 2025 will be published in the Gazette on Friday, seeking to enhance Hong Kong’s buildings energy efficiency management regime and lessen the financial burden on the public.
The Environment & Ecology Bureau noted that the proposed amendments aim to achieve a win-win scenario of saving electricity costs for buildings, reducing carbon emissions and boosting the development of a green economy.
The amendment bill contains five parts – regulating the energy efficiency standards of building services installations for all data centres in Hong Kong; requiring more types of buildings to conduct regular energy audits; shortening the intervals of energy audits; disclosing certain technical information in energy audit reports; and including more qualifications eligible for registration as Registered Energy Assessors.
The bureau said if the amendment bill is passed by the Legislative Council and implemented in full, it is estimated that an additional 500 million kilowatt-hours of electricity, equivalent to the annual electricity consumption of about 150,000 three-person households, could be saved in 2035.
The amendment bill will be introduced into LegCo for first reading and the commencement of second reading debate on March 26.
