EMSD has operated a voluntary Energy Efficiency Labelling Scheme for various kinds of appliances and equipment since 1995. The Scheme covered a number of product categories, ranging from household appliances and office equipment to cars.

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 Office (EEO) of the EMSD commissioned and completed a Preliminary Phase Study on the Wider Use of Water Cooled Air Conditioning System (WACS) in Hong Kong, China in 1999. The study found that WACS are much more energy-efficient and environmentally friendly than their air-cooled counterparts. Subsequently, EEO launched the Pilot Scheme of Wider Use of Fresh Water in Evaporating Cooling Towers for Air-conditioning Systems in 2000. The Scheme allows non-domestic buildings to use cooling towers in their air-conditioning systems.

In 1998, Electrical and Mechanical Services Department launched the Hong Kong Energy Efficiency Registration Scheme for Buildings (EERSB). The Scheme aims at reducing energy consumption of four major power consumption building services installations. Individual Building Energy Codes were also published for each of the four installations including air conditioning, lighting, electrical and lift and escalator installations. The Performance-based Building Energy Code was introduced in 2003. This code takes a total energy budget approach and allows greater flexibility to encourage innovations in building designs. With effective from 1 January 2018, all types of new and existing buildings/ premises (not limited to prescribed buildings) achieved energy performance outperform the minimum statutory requirements under the BEEO, with obtaining certificates of good building energy performance through the BEAM Plus Assessment System managed by the Hong Kong Green Building Council; or other internationally recognized building environmental assessment systems, can apply for joining the EERSB. Capital expenditure incurred on the construction of energy efficient building installations (include Lighting, Air Conditioning, Electrical and Lift and Escalator Installations) registered under EERSB may be eligible for accelerated tax deduction.

About 90% of total electricity consumption in Hong Kong is contributed by buildings. Through enhancement of building energy efficiency, greenhouse gas emissions can be effectively reduced. The Buildings Energy Efficiency Ordinance (BEEO) has come into full operation since 21 September 2012. The Ordinance is to promote enhancement of the building energy efficiency in Hong Kong through mandatory implementation of the Building Energy Code/Energy Audit Code on the prescribed building. The key requirements of the Ordinance include:

Benefit from effect of the Building Energy Efficiency Ordinance (BEEO), buildings built in recent years, both on design and installation, had already fulfilled various energy saving requirements. However, even those newly built buildings, which have the first commissioning process during handover, may not perform as expected due to various reasons, including deviation between design and actual operation, change of usage, behavioural change of occupants, etc. All those reasons will cause the building not to perform at its highest efficiency. Especially for Hong Kong, China, having the highest building density in the world, has more than half of buildings with an age of over 25 years. The saving potential from these buildings shall be significant. Among the various saving measures, Retro-commissioning (RCx) is a systematic and cost-effective process to periodically check the energy and other performances of an existing building. The process identifies operational improvements that can optimize energy efficiency performance of the buildings and thus lower energy bills. For details of RCx, please click here.
