In October 1998, the Electrical and Mechanical Services Department has launched the voluntary Hong Kong Energy Efficiency Registration Scheme for Buildings in order to promote the application of the Building Energy Code. To further promote building energy efficiency, the Government enacted the Buildings Energy Efficiency Ordinance which has come into full operation since 21 September 2012
機電工程署自1998年已推出自願參與的「香港建築物能源效益註冊計劃」，旨在推廣《建築物能源效益守則》的應用。為進一步推廣建築物能源效益，機電工程署已制定《建築物能源效益條例》，並於 2012 年 9 月 21 日 起全面實施
There are 3 key requirements of the Buildings Energy Efficiency Ordinance
- 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).
- 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.
- 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.
《建築物能源效益條例》的三大規定
1.新建建築物的發展商或擁有人須確保建築物內的空調、照明、電力、升降機及自動梯等 4 類主要屋宇裝備裝置，乎合《屋宇裝備裝置能源效益實務守則》（簡稱《建築物能源效益守則》）的設計標準。
2.建築物的負責人（業主、租客或佔用人等）在進行「主要裝修工程」時，須確保建築物內的 4 類主要屋宇裝備裝置乎合《建築物能源效益守則》的設計標準。
3.商業建築物（包括綜合用途建築物的商業部份，例如：住宅樓層下的商場）的擁有人須按照《建築物能源審核實務守則》（簡稱《能源審核守則》），為建築物內的該 4 類有關「中央屋宇裝裝置」每10年進行一次能源審核。
