About 90% of total electricity consumption in Hong Kong,China is contributed by buildings. Through enhancement of building energy efficiency, greenhouse gas emissions can be effectively reduced. In October 1998, the Electrical and Mechanical Services Department has launched the voluntary Hong Kong Energy Efficiency Registration Scheme for Buildings to promote the application of the Building Energy Code. To further promote building energy efficiency, the Government enacted the Buildings Energy Efficiency Ordinance (the Ordinance) which has come into full operation since 21 September 2012 (Note: Registration under the voluntary Scheme is not regarded as having complied with the Ordinance).

The 3 key requirements of the Ordinance

  1. The developers or building owners of newly constructed buildings should ensure that the 4 key types of building services installation therein, namely, air-conditioning installation, lighting installation, electrical installation as well as lift and escalator installation, comply with the design standards of the Building Energy Code (BEC).

  2. The responsible persons (i.e. owners, tenants or occupiers etc.) in buildings should ensure that the 4 key types of building services installation therein comply with the design standards of the BEC when “ major retrofitting works ” are carried out.

  3. The owners of commercial buildings (including the commercial portions of composite buildings, e.g. shopping malls under residential storeys) should carry out energy audit for the 4 key types of central building services installation therein in accordance with the Energy Audit Code (EAC) every 10 years.

Soft Reminder :

  1. The statutory requirement for compliance with the BEC (currently BEC 2018 Edition) applies to all major retrofitting works completed on or after the effective date of the BEC 2018 (i.e. 16 August 2019), irrespective of the commencement date of the works. In other words, even the major retrofitting works are commenced before 16 August 2019, they are required to comply with the BEC 2018 Edition if they are completed on or after 16 August 2019. If the responsible person of the major retrofitting works has difficulties to comply with certain requirements of the BEC 2018 Edition, the responsible person may apply, with justification, to EMSD for exemption from those particular requirements pursuant to section 20 of the Ordinance.

Application for registration as Registered Energy Assessor (REA)

To assist developers, owners or responsible persons to comply with the requirements of the Ordinance, the Ordinance sets up the role of Registered Energy Assessor (REA).
