    Statements on Notable Energy Developments

    Hong Kong, China

    The progress of energy developments and activities in Hong Kong, China (“Hong Kong”) thsince the 30 meeting of the Energy Working Group is summarised below:

    (1) Comprehensive Building Energy Codes

    The Hong Kong Government has promulgated Building Energy Codes (BECs) through its 1998 Hong Kong Energy Efficiency Registration Scheme for Buildings. The scheme covers lighting, air-conditioning, electrical, lift & escalator installations, and overall thermal transfer value of buildings. To encourage innovative energy-efficient building design features, a performance-based building energy code using total-energy-budget approach was published in April 2003. As of Feb 2006, there have been 600 venues registered in the Scheme.

    (2) Energy Efficiency Labelling Schemes

    As of end February 2006, the Government has issued labels for more than 2,700 appliance models including refrigerators, room coolers, washing machines, electric clothes dryers, compact fluorescent lamps, electric storage water heaters, electric rice-cookers, dehumidifiers, televisions multifunction devices, photocopiers, laser printers, LCD monitors, electronic ballasts, computers, and domestic gas instantaneous water heaters under voluntary Energy Efficiency Labelling Scheme.

    The voluntary Energy Efficiency Labelling Scheme has also been extended to cover Petrol Passenger Cars in February 2002, to raise the level of public awareness in the energy efficiency of vehicles. This was the first labelling scheme for vehicles in Hong Kong.

     (3) Energy End-use Database

    The Government has continuously maintained and updated the energy end-use database. The database provides useful insight into energy consumption patterns of different sectors, sub-sectors and the end uses in Hong Kong. A basic data set (Year 2003 basic data) from the database was published in September 2005 and is made available for public access at the EMSD website (

    (4) Alternative Fuel Vehicles

    In Hong Kong, almost all the diesel taxis had been replaced by liquefied petroleum gas (LPG) models. In August 2002, the Government launched a voluntary incentive scheme to encourage owners of existing diesel public and

    Page 2 of 5 EWG31/14.A (Hong Kong, China)

    private light buses to replace their vehicles with LPG or electricity models. About 2,400 diesel public light buses, representing over 80 percent of the newly registered public light buses have been replaced with LPG ones. The EMSD, being the Government department responsible for gas safety, is closely involved in the safety control and approval of the LPG vehicles, LPG filling stations, LPG vehicle workshops, as well as establishing and maintaining registers of trained LPG vehicle mechanics. In addition, the Government is continuously identifying possible ways to encourage vehicle owners to use cleaner alternative fuel. EMSD will carry on playing its role on advising gas safety.

     (5) Renewable and Clean Energy

    In late 2000, the Government commissioned a two-stage consultancy study to investigate the viability of using renewable energy technologies in Hong Kong, including a review of the associated institutional, legal, regulatory and financial issues. The first stage of the study was completed in 2002 and identified a number of new and renewable energy technologies as likely options for wide scale local adoption. These technologies include solar power, wind power, energy from waste and building integrated fuel cells. The consultancy study also involved the installation of building-integrated photovoltaic panels in an existing high-rise building, as the second stage of the study, to demonstrate to the general public the applicability of photovoltaic technologies. The installation was completed in end 2002. The performance of the photovoltaic system was monitored over a 12-month period so as to collect technical data to assess their performance under local weather and environmental conditions. The whole consultancy study was completed in 2004.

    Further demonstration projects on renewable energy power systems have also been implemented by the Government to promote public awareness in renewable energy. A total capacity of about 550 kW has been installed in 8 government projects over the past two years. Apart from solar energy, a small scale wind-turbine has been installed on the rooftop of EMSD’s Headquarters to facilitate

    studies to be carried out on the application of wind power system in an urban environment. Moreover, one of the two power companies in Hong Kong has put Hong Kong’s first commercial scale wind turbine of 800 kW into service in

    February 2006. The wind turbine is expected to produce 1 GWh of electricity a year. The other power company has also agreed to set up similar pilot commercial scale wind turbine project for public demonstration and evaluation purposes, subject to detailed feasibility studies.

In the First Sustainable Development Strategy for Hong Kong published in May

    2005, the Government has put forth a target of having 1% to 2% of Hong Kongs

    total electricity supply met by renewable energy by the year 2012. This target is subject to regular review in the light of advances in technological solutions and emerging sustainability considerations.

    (6) Consultancy Studies on Wider Use of Water-cooled Air Conditioning System (WACS)

    The Government has completed three consultancy studies on the energy saving potential of WACS. One is on the territory-wide implementation of WACS and the other two are on the implementation of district cooling system in a new development area and an existing developed area. The Government is materializing some recommendations put forward by the studies, such as increasing the designated areas in the territory for allowing the use of fresh water cooling towers in non-domestic buildings.

    (7) Energy Consumption Indicators and Benchmarks

    The Government has developed energy consumption indicators and benchmarks for hospitals, clinics, universities, schools, hotels and boarding houses, private offices and commercial outlets in the commercial sector, as well as medium and heavy goods vehicles, private cars and light goods vehicles in the transport sectors. The indicators and benchmarks enabled targeted groups to set its own improvement targets, and identify and implement improvement measures. The indicators as well as on-line benchmarking tools were made available at the EMSD website, where individual operators could benchmark their energy consumption with others in the same group.

    (8) Life Cycle Energy Analysis for Commercial Building Developments

    In Hong Kong, commercial buildings are responsible for 34 percent of the city’s total energy end-use. Enhancing sustainability of building development is of paramount importance to the sustainability of Hong Kong. To achieve this goal, the Government has developed a software tool for assessing the energy use, environmental and cost impact of building development. It integrates the approaches of Life Cycle Analysis and Life Cycle Costing for decision-making on commercial building development. The software tool is being distributed free of charge to the local industry.

    (9) Energy Saving Programmes in Public and Private Sector

    To demonstrate its commitment to protect the environment, the Government of Hong Kong sets targets in March 2003 to cut down the annual electricity consumption of Government departments by 1.5%, 3%, 4.5% and 6% in Financial Year (FY) 2003-04, 2004-05, 2005-06 and 2006-07 respectively, using FY 2002-03 as the base year. Since then, EMSD has been providing technical support and expert advice to Government departments by publishing energy saving tips and guidelines, organising experience sharing workshops, advising on good housekeeping practices, implementing energy saving retrofits etc. With these efforts in place, a saving of about 3.6% in electricity consumption of Government departments was achieved in the first two years since the targets were announced.

    In line with Government’s drive to save energy, an energy saving competition aiming to recognize best practices among Government departments in energy efficiency and conservation was launched in 2003. Some 192 entries from various departments, accounting for 48% of the total Government consumption, participated in the competition. The overall saving achieved by the participants was 5.9% in the one-year competition period.

    A similar competition titled “Hong Kong Energy Efficiency Awards” was launched in October 2004 for the private sector to help property management organisations and schools build up stronger sense of environmental protection and sustainable energy use. Encouraging responses to the Awards were received and some 230 entries went through the one-year competition period with due diligence and enthusiasm.

    In Hong Kong, it is estimated that air conditioning systems consume about one-third of total electricity consumption of the whole territory. In order to reduce electricity consumption, the Government initiated a policy in October 2004 to maintain the air-conditioned room temperature of Government premises at 25.5 deg C in summer months. In June 2005, the Government further promoted the 25.5 deg C initiative to the public as one of the themes of World Environment Day 2005.
