Invitation for Response Document > Executive Summary
|
This Invitation for Response (IR) Document seeks to invite interested individuals and organisations to give their views and comments on achieving energy saving and enhancing energy efficiency in buildings that will lead ways to combating climate change. The public engagement exercise aims to facilitate the exchange of ideas on the concerns, incentives and possible action plans for the demand-side management in electricity consumption and carbon intensity reduction.
Some 90% of Hong Kong's electricity is consumed in buildings and buildings alone account for about 60% of Hong Kong's greenhouse gases (GHGs) emission. The Council for Sustainable Development (SDC) recognised that buildings are an important area for climate change mitigation actions and proposed to focus strategically on four core building user groups, i.e. household, office, retail and catering, in order to maximise building energy efficiency and reduce carbon emissions.
Climate change in its simplest term refers to changes of climate that are attributed directly or indirectly to human activities. Such changes are usually measured or noticed in the long term variations of the weather conditions, e.g. temperature, precipitation and wind patterns. In Hong Kong, meteorological observations in the past century reveal that there is a long term increasing trend in the city's average temperature and annual rainfall. The annual number of hot days/nights and annual rainfall are expected to increase over the coming decades. There will also be more occurrence of extreme weather.
Changes in climate will inevitably affect where and how people, plants and animals live, such as impacts on food production, accessibility and use of fresh water, and health risks. To alleviate climate change and its related impacts, both supply-side and demand-side management measures should be adopted. Innovations of renewable energy should be actively explored while every Earth citizen should revamp our conventional ways of living and pursue higher energy efficiency resulting in reduction in carbon emissions. Tackling climate change from the demand side will help achieve the higher goal of sustainability: saving energy means saving natural resources, reducing carbon emissions and saving costs.
In 2008, Hong Kong's GHGs emission per capita were about six tonnes. In terms of sectoral contribution, electricity generation accounted for about 67% of our total emissions (2008 figure), whereas transport sector accounted for 18% and waste for about 5%. Electricity consumption per capita in Hong Kong has been continuously increasing and figures in 2008 showed that 89% of our city's electricity is consumed in buildings. In other words, buildings account for about 60% of Hong Kong's GHGs emission. These lay down a very strong case for targeting the four building user groups for territory-wide reductions in energy consumption and carbon emissions.
The SDC has identified household, office, retail and catering as the four core building user groups with the aim to allow for a more focused discussion on how each group can maximise energy efficiency and minimise carbon emissions in building uses. These four groups cover a wide spectrum of the general public as well as practitioners in the area of estate management and trades.
To effectively channel in views from the stakeholders and the public, the engagement programme involves different activities. A series of informal meetings were arranged to pick the brains of members of the SDC and its sub-committee in the early stage; five focus group meetings were arranged in April and May 2011 to solicit views and concerns from the target building user groups. These initial findings and research on local and overseas experience have formed the basis of this IR Document to facilitate informed and structured discussions among the stakeholders in the building user groups as well as in the wider community.
The public engagement process will take place from August to December 2011, five regional forums will be carried out to gauge public's ideas on possible incentives, concerns and actions in energy saving and energy efficiency in building related activities.
To help promote the engagement activities, more than 60 organisations would join the engagement programme as Supporting Organisations. These organisations, including tertiary institutions, research institutions, green groups, government and non-governmental organisations, as well as other business-related and professional organisations, are engaged to help disseminate invitation to the engagement exercise.
Existing measures for the promotion and implementation of energy efficiency in buildings can be discussed in four broad areas: regulation, financial assistance, incentive scheme and government leading by example.
Regulation currently mandated by the Government includes:
|
Buildings Energy Efficiency Ordinance (The Ordinance) which regulates compliance with the Building Energy Code to make building services installations more energy-efficient. The subjected building services installations include lighting, electrical, air conditioning and lifts and escalators installations. The Ordinance also mandates commercial buildings or commercial portion of composite buildings in Hong Kong to conduct energy audit once every ten years.
|
|
Energy Efficiency (Labelling of Products) Ordinance requires energy labels to be displayed on prescribed electrical products before being supplied in Hong Kong to facilitate consumers in choosing energy-efficient electrical appliances. The Voluntary Energy Labelling Scheme was also set up for 19 types of household appliances and office equipment to encourage manufacturers and suppliers to market more energy-efficient products.
|
|
Overall thermal transfer value (OTTV) is a measure of the energy consumption of a building envelope and applicable to commercial buildings and hotels as defined in the Building (Energy Efficiency) Regulation.
|
|
Financial assistance is another form of support offered by the Government with the aim to speed up the implementation of energy saving measures. Buildings Energy Efficiency Funding Schemes were launched in 2009 to provide financial support to building owners to conduct energy-cum-carbon audit as well as to conduct energy efficiency improvement projects that enhance buildings energy efficiency, and thus reduce carbon emissions from building related activities.
There are also programmes initiated by the Government and other related organisations with the aim to raise awareness of and facilitate actions in energy saving and carbon reduction. Some of these examples include Hong Kong Awards for Environmental Excellence, “Green Hong Kong · Carbon Audit” campaign, and various online tools such as carbon calculators and carbon audit toolkits to enable the public to get familiar with the concept of energy consumption and carbon reduction.
Based on the findings from meetings with various stakeholders as well as reviewing local and overseas examples, the SDC puts forward an initial list of possible actions with a view to facilitating further discussion in the community. These possible actions are considered adoptable by one or more of the four building user groups in achieving higher energy efficiency and carbon reduction. These ideas can be categorised into systemic enhancement and facilitation of behaviour change.
Six possible actions are identified under systemic enhancement:
- To consider tightening the Building Energy Code (BEC) - other countries such as Australia have put in place national standards making minimum energy performance requirements for new buildings and major refurbishments statutory. In view of the current BEC covering four building services installations, i.e. lighting, electrical, air conditioning and lift and escalator installations, comments were received on the possible tightening of the current performance standards of these building services installations as well as extending the requirements to other installations.
- To consider providing recognition for buildings achieving high energy efficiency – it was a general consensus at the focus group meetings that good practice in making buildings more energy-efficient should be recognised. At present, BEAM Plus is a comprehensive assessment scheme available in Hong Kong. The scheme is recognised and accredited by the Hong Kong Green Building Council.
- To explore extension of the application of the Mandatory Energy Efficiency Labelling Scheme (MEELS) – the MEELS is well-received by many users in the community. Suggestions were received on extending the scheme to include other electrical appliances. The current lists of appliances under both the mandatory and voluntary schemes should be revisited to cover more commonly used electrical appliances to allow customers to make informed choices when buying electrical appliances.
|
|
- To consider tightening up the energy efficiency grading levels for room air conditioners and refrigerators under the MEELS – building on the potentials of the MEELS, members of the focus group meetings suggested to further tighten the energy efficiency grading levels for room air conditioners and refrigerators, the two appliances that are used most often and have contributed to a significant portion of electricity use within buildings.
- To explore phasing out energy-inefficient incandescent light bulbs – referring to international trend, there is wide spread movement to phase out incandescent light bulbs and target phase-out years were set. Australia, Canada, Korea and the United States are just some of the examples where the national target phase-out year has been mandated.
- To explore phasing out energy-inefficient electrical installations/appliances – apart from the phasing out of incandescent light bulbs, other energy-inefficient electrical installations/appliances can be explored. In Japan's experience, 21 household and office appliances including air conditioners, TV sets, computers, microwaves, heaters and rice cookers, etc. are currently under a regulatory scheme designed to stimulate the continuous improvement of the energy efficiency of products by setting target values based on the current highest efficiency level of each type of product in the market instead of the current average efficiency level.
|
On the facilitation of behaviour change, five areas of action are proposed:
- Energy/Carbon audit – drawing experience from overseas cases and leading examples from local trades, energy/carbon audit is useful in providing an indication on operations’ performance in electricity consumption and GHGs emission. These sets of information indicate possible areas for improvement and may eventually lead to potential cost savings. Possibility should be explored on introducing energy/carbon audit to priority groups of operations/building user groups, such as government departments and public housing estates, large corporations, listed companies, etc.
- Better understanding of your energy consumption – if building users have access to a year-on-year (by month) comparison of their own energy consumption, i.e. informative electricity bills, they may start to review their consumption pattern and undertake any possible behaviour change to save cost and energy use. Allowing building users to make reference to average energy consumption, such as in “per-capita” and “per-square meter” basis, will also enable them to benchmark their own level of consumption.
|
|
- More use of energy efficiency management systems – a number of information technology products and intelligent building environmental management systems are currently available to facilitate users to adopt energy-efficient practices. It was suggested to further promote the use of these management systems.
- Promote adoption of energy-efficient electricity appliances among the trades – the availability of energy-efficient electrical appliances is important to local trades who wish to invest in energy saving. Research & development and innovations on these electrical appliances should be actively promoted to encourage a wider choice for users. Publicity and dissemination of the latest information on highly energy-efficient electrical appliances should be made available to the trades and the public.
- Electricity tariff structure review – in the context of facilitating behaviour change, it was suggested to review the current electricity tariff structure on the basis that a fine-tuned tariff structure could change the operation of electricity cost-sensitive businesses/organisations.

Climate change and its related issues may be too broad and abstract to comprehend for most of us. Relating the topic with energy efficiency, energy saving and cost saving would help lay down the context for solid actions and implementation. We hope that the proposed actions may help trigger more thoughts from everyone in the society so that public discussion can be fruitful taking into account the considerations of people from all walks of life. A list of questions is proposed to stimulate further discussion with a view to building consensus on the way forward for alleviating climate change through improving the efficiency of energy use in buildings.
