Energy Efficiency & Conservation

Energy & Our Environment

Energy is all around us, simply as heat and light, and in more complex mechanical, electrical, chemical and nuclear forms. Find an overview of how you can be energy efficient.

Voluntary Energy Efficiency Labelling Scheme

In recognition of the need to improve energy efficiency in Hong Kong, the Government has introduced a voluntary energy efficiency labelling scheme. Learn more about the scheme, the types of appliances and equipment it covers, and where you can check if a product is registered.

Mandatory Energy Efficiency Labelling Scheme

To further facilitate the public in choosing energy efficient appliances and raise public awareness on energy saving, the Government has introduced a mandatory Energy Efficiency Labelling Scheme (EELS) through the Energy Efficiency (Labelling of Products) Ordinance.

Energy Efficiency Registration Scheme for Buildings

Another energy efficiency initiative is the Energy Efficiency Registration Scheme for Buildings. This voluntary scheme encourage building owners achieving better energy performance beyond the statutory requirements.

Buildings Energy Efficiency Ordinance (Cap. 610)

To improve building energy efficiency, the Government formulated the Buildings Energy Efficiency Ordinance. Under the Ordinance, certain prescribed types of buildings have to comply with Building Energy Code (BEC) and/or Energy Audit Code (EAC).

Scheme on Fresh Water Cooling Towers

The use of fresh water cooling towers can significantly reduce electricity consumption in air conditioning. The Government has launched a voluntary scheme on fresh water cooling towers for non-domestic buildings in designated areas. For premises outside the designated areas, applications are also welcomed subject to adequacy of fresh water supply.

Scheme of Control Agreements

The electricity market in Hong Kong has all along been regulated through the Scheme of Control Agreements (SCAs) signed between the Government and the two power companies. The SCAs set out the obligations of the companies, the returns for shareholders and the arrangements by which the Government monitors the companies' electricity-related financial affairs.
