Chapter 1: Introduction
Background:
Quality Improvement and planning within the organisation can develop the required
competency for ensuring the long-term success factors of the business procedure. Throughout
the quality improvement plan the existing operational procedure has to be assessed. The
strategic management procedure to improve the quality of the system is known as Quality
management (Shaikh et al. 2014). Various internal operations, external process, regulatory
guidelines along with the resultant impact on the workflow, inventory, performance,
infrastructure and client base are the core components that have to be considered in quality
improvement process. These interconnected and strategic business operations are collectively
called the Quality Management System or QMS of a business platform. Quality management
System or QMS also requires effective financial measurement, recording of evidence,
requirement assessment, interactive communication, workforce training, measurable activities
and information integrity. The most essential extensive part of the Quality management and
Improvement system is the Risk Assessment and Mitigation plan. Quality improvement is
able to increase the performance of organisational operation in one hand and reduce the
operational cost on the other hand. QMS is also a very effective business strategy aimed
towards the financial benefit, which can also ensure high return on investment while leading
the high profit margin. At the same time, in quality management system an organisation
needs an expletory market analysis along with examination of scopes.
Research Rationale:
Every nation foresees and seeks for a better economic condition and always tries to be
a larger power generation hub than the importer. It is a herculean task for any nation that also

Introduction
The literature review section of this research will discuss all the basic components of
the topic energy management system and the scopes to improve the quality management in
Hong Kong. The online and offline articles, journals, books, government report and private
publication are used as data source for literature review. The aim of this literature review is
evaluating the research topic through reviewing several other research and documents.
Throughout the Literature review the key area of discussion will be the existing energy
consumption and production in Hong Kong, the international standardisation of energy
management system, macro analysis of Hong Kong industries and businesses, the Energy
Management System Industry in Hong Kong, Situational Dynamics and drivers, restraints
and opportunities.
Energy Consumption and production in Hong Kong
Around 65% of the total electricity in Hong Kong is consumed by the buildings. This
large amount of energy consumption is a result of operating domestic and commercial
electrical equipment and the installation of those equipment. The efficiency of those
equipment also contributes to the mechanical efficiency and subsequently the consumption of
electricity. In last 5 years the average electricity consumption per year is 41.74 billion kWh,
per capita 5,647 kWh. The majority of the energy consumed for Hong Kong city is derived
from external sources. The energy is either directly imported from the as the oil products and
coal products or produced from intermediate transformation process using imported fuels. In
terms of electricity, Hong Kong partially executes a self-produced energy scheme. The total
production of the electricity is 36bn kWh, 86% of the total usage of the country. Hong Kong

The total energy consumption in domestic purpose is gradually increasing. However,
the percentage share of industrial electricity consumption is decreasing. At the same time, the
commercial buildings contribute to the total electricity consumption by 66.2%, which makes
the total energy consumption by the building higher that expectation. When it comes to the
consumption of Gas, domestic consumption has the maximum intake of gas. However, being
very low consumer of gas, the industry based operation has increased the consumption of gas
by 2% from 2007 (ev.hkie.org.hk 2019).

Energy Management System (ISO 50001)
The ISO 50001 Energy management System can be described as a standard which is
created by the International Organization for Standardization (ISO) and it defines the
requirements of the Energy Management System. The ISO standard specifies the various
requirements associated with the improving, maintaining, implementing, establishing the
Energy Management System. This enables organizations, countries to follow a systematic
approach for the consistent improvement in the energy consumption, energy use, energy
security, energy efficiency, energy performance. ISO 50001 aims towards the facilitation of
the establishment of the processes and the systems so the energy performance of the
organization is improved and it includes the consumption, energy efficiency use (Fiedler and
Mircea 2012).
Before the ISO 50001 there were other standards in the world, there have been around 14
local energy/regional energy management standards. Studies conducted have shown that the
previous energy management systems were having common features. The ISO 50001 has
vital improvements when compared with the European Energy Standard EN 16001:2010. The

Act (PDCA) cycle and the ISO 50001 integrates easily with these systems.
The two dimension that characterize the difficulties with the adoption of the ISO 50001 are
the organizational difficulties and the operational difficulties. There are however certain
benefits that pertain to the operational benefit and ecological benefit. Three sources of
motivation have been identified through and exploratory factor analysis which includes the
competitive advantage, ecology drivers, social requirements. The analysis conducted have
shown that the social requirements explain the operational difficulties and this result into
operational benefits. The ecological benefits are related directly with the ecology drivers.
Organizational difficulties have an inverse relationship with the ecological and the
operational benefits (Marimon and Casadesús 2017). The efficiency associated with the
energy usage enables nations and organizations to save money and at the same time helps in
the conservation of the natural resources. subsequently, this process helps in the prevention
of the natural resources. The extent to which the Energy Management Systems (ISO 50001)
positively contributes to saving the natural resources also helps in the stabilizing the climate
parameters. This on the other hand interests helps the international associations and the
governmental institutions to deal with the environmental resources.
Energy Management includes the energy production, distribution, consumption,
resource utilisation and energy recycling (Imes, Hollister and Allure Energy Inc 2013).
Effective energy management is not only providing the better opportunity to increase the
operational profit, it is also a basic requirement of every industry in this era of energy
conservation. In 2011, International Organisation for Standardisation or ISO released a new
energy conservation management guideline for every organisation irrespective of their size,

Mancarella and Mutale 2015.). The purpose of this standardisation is to enable an
organization to abide by a systematic approach in achieving continual improvement of energy
performance, including energy efficiency, energy security, energy use and consumption.
The ISO 50001 Energy management system has been fatherly raised, where an
organisation should demonstrate their improvement in the performance of electrical
equipments and electric consuming operation. There is no specific margin to quantify the
appropriate energy consecration limitation. It is more about a corporate responsibility that
every business organisation should have while executing the business operations, especially

Macro analysis of Hong Kong industries and businesses
The economic situation, political stability, legal business policies and social
perception of the population have huge impact over the energy consumption of any nation.
The economic alteration as a result of globalisation influences these changes to some extent.
In case of Hong Kong, this city is connected to the wider commercial web as major value
exchange hub. As a result, the industrial development is also noticeable. Technological
development also defines the mechanical efficiency of the equipment and that regulates the
energy consumption for domestic, Industrial and commercial area.
The macro analysis of Hong Kong includes the Legal, Economic, Social and
technological considerations with regards to the Energy Management System. Hong Kong is
a Special Administrative Region of China, where the strict environmental laws and
regulations are enforced by the national as well as the local government and authorities. The
People’s Republic of China has a strong administrative infrastructure to ensure controllable

Mancarella and Mutale 2015.). The purpose of this standardisation is to enable an
organization to abide by a systematic approach in achieving continual improvement of energy
performance, including energy efficiency, energy security, energy use and consumption.
The ISO 50001 Energy management system has been fatherly raised, where an
organisation should demonstrate their improvement in the performance of electrical
equipments and electric consuming operation. There is no specific margin to quantify the
appropriate energy consecration limitation. It is more about a corporate responsibility that
every business organisation should have while executing the business operations, especially
which are linked with energy consumption. The three phases of this Energy Management

renewable energy development projects in Hong Kong mainly comprises of the pilot projects
that are government initiatives and the initiatives of the power companies. The pilot projects
have made it easy to confirm the potential of Hong Kong towards the development of

Barriers to the Renewable Energy Development
Hong Kong has high potential to become self-reliant in terms of renewable energy,
however there are several hindrances that can hinder the development of renewable energy in
Hong Kong. There are physical limitations that pertain to the lack to space and it is one of the
obvious barrier. It is important to mention that Hong Kong is a city with a very dense
population and it has very few flat areas. Majority of the renewable energy requires a lot of
dispersed areas for the effective generation of electricity. The small scale distribution factor
system is limited by the space factors and due to this reason the rooftops of the Hong Kong
buildings are utilized for various activities storage for the equipment, sport facilities,
playgrounds, gardens. Thus, the renewable energy systems that are placed on the rooftops
compete with the other alternative sources. Another major barrier is the lack of the policy

economic and the political system. Furthermore, the other regions of China are bounded by
the laws but the scenario is similar for Hong Kong (Zhang, Shen and Chan 2012). It is
important to note that the Hong Kong is not bounded by the carbon laws, and energy laws
and policies that are set up by the central government. Hong Kong has no central government
and there are carbon/energy targets set like the other regions. The political context of Hong
Kong has contributed towards the promotion of the renewable energy. There has been no
revision of the targets other than the one that are set since the target of 1-2 percent. Hong
Kong has recently released the Hong Kong Climate Action Plan 2030+ and this plan has
suggested that Hong Kong government can achieve a target of 3 to 4 percent by the year
2030. However, it is important to mention that the Hong Kong failed to achieve the target of
3 to 4 percent (Zhang et al. 2012). There is as such no policy that can support the distributed
system of renewable energy. This has led to the creation of the policy void and the
international experience shows that the renewable energy depends on the policy support
measures which includes the low interest loans, direct subsidies, renewable energy portfolios,
net metering and feed in tariffs. Hong Kong presently has no policy that can internalize the
various factors related to the carbon emission, like the emission trading or carbon taxes. This
strategy will greatly affect the renewable energy when Hong Kong is already competing with
the fossil fuel. However, in contrast the mainland China has established the feed in tariffs for
the wind and the solar energy but it is also moving towards the national carbon market. The
lack of the policy support will result into a delay in the procurement of the energy equipment.
In Hong Kong the slow approval processes and the complex planning requirements have led
to the inhibition of the development of the renewable energy in Hong Kong. For example, the
building regulations do not have the provisions of disallowing the installation of solar

Energy from sewage treatment
Sewage is normally treated as a waste and it is generated in Hong Kong due to the
everyday activity. Due to the advancement in technology, sewage can be converted into
energy effectively and efficiently through the application of the sewage treatment processes.
Before moving the waste to the land fill sites, the stabilization process is applied to the sludge
for the secondary treatment process and also for the removal of the harmful substances. For
the stabilization of the bio-solids a traditional process of anaerobic digestion is used which is
used for the treatment works worldwide. Organic materials of the sludge are broken down
into a less harmful inorganic product that has various kinds of gases and it is produced as
biodegradation of the organic materials (Poon 2016). Sludge is produced during the
secondary process and the basic principle of the sludge treatment is the decomposition of the
biological waste by biological organisms in the absence of oxygen. This process involves the
usage of different types of the microbes (methanogens and bacteria). The organic materials
are then broken down into much smaller substances. The organic materials consist of the
sludge that are broken down into the less harmful organic materials and along with it the
various kinds of gases also release due to the biodegradation of the organic materials. The
gases specifically are called as biogas. Biogas which is produced during the anaerobic
digestion of the sludge consists of 60 to 65 percent of methane by volume, 35 to 40 percent of
carbon dioxide, with small amounts of water vapour, hydrogen sulphide, hydrogen, nitrogen
and other gases. The heating value of biogas is generally calculated to be 22.4 MJ/m3. There
are four major secondary treatment works that produce the biogas and the four sites include
the Yuen Long Sewage Treatment Works (STW), Shek Wu Hui STW, Tai Po STW, Shatin

Power technologies and combined heat- The technology of cogeneration is also called
the combined heat and power (CHP). Cogeneration can be descried as a technology that can

Micro-turbine- A micro-turbine is smaller in size in comparison to the regular sizes.
The operating principle of biogas combustion involves the creation of a high pressure of air
flow. The air flow makes the turbine propellers to turn the shaft and this drives the generator
for the production of the electricity. The design of such micro-turbine consists of
recuperators, single stage radial turbine, single stage radial compressor. Manufacturing and
design of the recuperators goes through the fulfilment of the stringent requirements due to the
fact the micro turbines operate under the extreme temperature differentials and high pressure.
The heat from the exhaust can also be used for the absorption of chilling, drying process,
space heating, water heating (Chen and Ni 2014). The efficiency of a typical electrical micro-
turbine ranges from 25 percent to 35 percent. Thus, when the micro-turbine operates in a heat
and power cogeneration combined system which has the efficiency of more than 80 percent.
It has been found that the turbine systems have several advantage over the reciprocating
engine generators like the higher power density, few moving parts and extremely low
emissions. Turbines are advantageous over the majority of the heat contained in the high
temperature exhaust and the heat generated from the waste in the reciprocating engine is split
into the engine cooling systems and exhaust. However, it is important to note that the
reciprocating engines respond quickly and the respond to the changes accordingly and they
are slightly more efficient. The micro-turbine efficiency has lower efficiency in comparison
to the reciprocating engines (Fong and Lee 2015).
Recent development of Combined heat and power generator- The first CHP generator
was commissioned in the year 2006 at the Shek Wu Sewage Treatment Works and later on it
was then connected with the CLP power distribution network. The total capacity of power
generation from the biogas is estimated to have reached 1590 kW. Furthermore, it has also
been seen that the generators have converted about 9.32 million m3 of biogas to 20.2 million
kWh of electricity. This is equivalent to an annual electricity consumption of 2,240
Micro-turbine- A micro-turbine is smaller in size in comparison to the regular sizes.
The operating principle of biogas combustion involves the creation of a high pressure of air
flow. The air flow makes the turbine propellers to turn the shaft and this drives the generator
for the production of the electricity. The design of such micro-turbine consists of
recuperators, single stage radial turbine, single stage radial compressor. Manufacturing and
design of the recuperators goes through the fulfilment of the stringent requirements due to the
fact the micro turbines operate under the extreme temperature differentials and high pressure.
The heat from the exhaust can also be used for the absorption of chilling, drying process,
space heating, water heating (Chen and Ni 2014). The efficiency of a typical electrical micro-
turbine ranges from 25 percent to 35 percent. Thus, when the micro-turbine operates in a heat
and power cogeneration combined system which has the efficiency of more than 80 percent.

households having 4 members. This in terms of money represents a savings of roughly HK$
20 million in electricity costs. Thus, it can be said that greenhouse gas emission has reduced
to a large extent after the installation of the CHP generators and it is equivalent to 14,000 tons
of carbon dioxide (Skorek-Osikowska et al 2014). By the end of 2013 and the early part of
2014, two other CHPs were commissioned which included the Tai Po STW and Shatin STW
that has the capacity of 630 kW ad 1400 kW respectively. CHP is considered to be the one of
the fastest growing installations in the DSD and along with it is one of the best ways of
turning waste to a resource and the process includes recovering the chemical energy from the
sewage sludge and chemical energy. DSD continues to explore the feasibility of adding CHPs
into the sewage treatment works for catering to the increasing demand of sewage treatment.
This is done to remain in sync with the latest developments of CHP and along with it also
view the enhanced energy saving (Kopanos, Georgiadis and Pistikopoulos 2013).

Landfill gas collected from the landfill sites including the solid wastes is utilized for
the electricity generation. The electricity generated is used as a heating fuel to heat up the
leachate treatment plant and also for onsite consumption. The extraction of landfill gas is
controlled through an automatic system, so that the landfill can be transferred to the different
consumption units at set pressures and quantities. There was an agreement for the joint
development of the of a project aimed towards the use of the landfill gas as heating fuel in a
gas production plant located in Tai Po. Keeping in mind the cost-effectiveness issue, a
treatment unit has been set up in NENT so that he non-methane hydrocarbon, hydrogen
sulphide and carbon dioxide is removed from the raw landfill gas. The product gas also called
the Synthetic Natural Gas consists of the 80 percent of methane and it is delivered to the gas
production plant of Tai Po as a heating fuel through and underground pipeline. One of the
important aspect of Tai Po gas production plant is the stage where steam is formed and at this
same stage methane is converted to hydrogen (Woon and Lo 2013). The synthetic natural gas
used in the Tai Po gas production plant has led to the reduction of the 43,000 of naphtha per
year. This measure of naphtha is almost equal to 135,000 tonnes of carbon dioxide emission.
The energy supplied from the NENT is about 2510 TJ and this has helped in the emission of
53,000 tonnes of naphtha and at the same time has avoided the 166,000 tonnes of carbon
dioxide emission. There are a lot of hurdles associated with the selling of the electricity
generated from the landfill gas to the electricity grid. Due to the certain reason the power
generated from the landfill can be used only internally. It is important to mention that the
town gas that was previously distributed in Hong Kong is not a natural gas. While the natural
gas cannot be burned safely in the town gas appliances. Furthermore, landfill gas even if
upgraded to natural gas cannot be injected into the town gas for the industrial, commercial

it to fuel the natural gas vehicles. The natural gas vehicle is not available in Hong Kong yet
and the introduction of the same might raise question on the feasibility, due to the lack of the
any kind of legislation and infrastructure (Woon and Lo 2014).
Situational Dynamics and drivers, restraints and opportunities
The commercial and large residential buildings contribute around 90% of total
electricity consumption in Hong Kong (Han et al. 2014). By enhancing the energy utilisation
efficiency and consumption emission can be effectively reduced. The Electrical and
Mechanical Service Department of Hong Kong has a voluntary Hong Kong Energy
Efficiency Registration Scheme to promote the procedure of increasing energy efficiency.
Before implementing the energy consumption efficiency plan, any organisation should have
the ability to control the energy intensive equipment of the building. The energy waste should
be identified and reduced through enteiliWEB’s link to the building energy usage automation
system (en-trak.com 2018). EnteiliWEB is an energy toolkit that provides a significant link
between monitoring and control. In energy management process an organisation should
develop a dynamic plan to execute the crucial operations namely High level commitment,
prepare an energy Policy, energy management plan, Energy Audit, Formulation of plan of
action, Implementation of the action plan, evaluate, energy saving achievement and return to
energy management change if required (Zhao et al. 2013).
In 2010 “Hong Kong Climate Change Strategy and Action Agenda” a public
consultation document was issued by the HKSAR Government. This document proposed that
the Hong Kong city needs to adopt alternative voluntary reduction target for carbon emission.
The proposed target increased the previous reduction target based on 2005, which was 50%
to 60% by 2020. This change looked forward from the previous projected target of China in

2009 which was 40%to 45%. To achieve the declared target Hong Kong Government
published a new proposal which was a consultation paper for the Substantially Revamp the
Fuel Mix to generate electricity. This new technique of electric generation presented with
new mixing ration and targets, such as imported nuclear energy for 50%, natural gas for 40%,
coal for 10% and renewable energy for 3% to 4% of the total fuel volume. The target of this
new electric generation procedure was set for 2020 (epd.gov.hk 2019). Considering the
Fukushima event in 2011, the previous electricity generation target became difficult to
achieve properly while spending less amount of national assists. This new fuel mix ratio was
influenced by the public consultation paper from 9th March to 9th June, 2014, in order to
balance the competitive energy objective while taking care of the safety, reliability,
affordability and environmental performance.

Hong Kong has been already confirmed by the Government commitment and stakeholders’
engagement procedure. For cleaner power generation process various efforts are being
invested within the building sector involving various instruments abiding by the Scheme of
Control Agreement. This agreement refers the cooperation between Government and energy
companies, Buildings Energy Efficiency Ordinance, BEAM Plus and the Energy Efficiency
Labeling Scheme. The purpose of this agreement is to deal with energy consumption and also
the greenhouse gas emissions (Mesthrige Jayantha and Sze Man 2013). Air Pollution Control
Ordinance has already achieved 30 scores in Improvement of air pollutant emissions
reduction. Considering all the reduction strategies and outcomes for decreased greenhouse
gas emissions, constructive conditions have been already proposed with the introduction of
new fuel mix policy. The new fuel mixing strategy is ha huge shift from coal to gas for
electricity generation. It has the potential to make significant difference and improvement.
Another challenging outcome of climate change is increasing resilience of energy
infrastructure against extreme and destructive weather conditions and events. These events
can disrupt the entire energy supply and can even damage production plants and other
valuable distribution assets. The Recent extreme weather events in South China and the PRD
region is the best example, which is constantly pointing out the importance of the need for
greater adaptability and resilience of energy infrastructures. Holistic support for the
development of proper infrastructure and diversification of cleaner energy source different

significant weak point that is the low availability of land. It is becoming the most critical
challenge for local as well as on-shore development of the renewable energy. Therefore, it is
clear that to make the interventions economically and technically feasible large scale green
power sources such as offshore wind farm or solar power is necessary (Hensen.com.hk 2019).
Future Prospect of Energy Management System through quality management in Hong Kong
One of the major targets of the government of Hong Kong is to reduce the energy
intensity by 25% within 2030 from the energy consumption level of 2005 level. In September
2007, it has been as set out in the APEC Leaders' Declaration on Climate Change, Energy
Security and Clean Development issued. As per the discussion and on this Annual Seminar,
building was identified as the largest energy consumer. It has been found that building
considering the commercial and residential sector consumes about 90% of the total electricity
used in Hong Kong. At the same time it generates about 66% of greenhouse gas emissions (as
shown in Fig.2). Therefore, efforts are being invested in cleaner power generation process
and in the building sector for energy efficiency through number of instruments including
Buildings Energy Efficiency Ordinance, establishment of BEAM Plus and the Energy
Efficiency Labelling Scheme to raise environmental impact awareness, promote green
building, energy efficiency and renewable energy. Under the Energy Efficiency Labelling
Scheme, for supply in Hong Kong the energy labels are required to be shown on the products
to inform consumers regarding their energy efficiency performance (Imes, and Hollister,

Sustainability challenges and Energy policy reforms
In the year 2010, The Hong Kong Special Administrative Region issued a
consultation document that proposed that Hong Kong must reduce the carbon intensity target
by the year 2020 and the target is of 50 to 60 percent. The proposal was in line with the target
2020 of China which was announced by the 2009, and the reduction was 40 to 45 percent of
carbon intensity. In order to achieve the target, the Hong Kong government went with the
mixing fuel for the generation of electricity by the year 2020. This has been done to
compensate for the renewable energy (3 to 4 percent), coal (10 percent), natural gas (40
percent), and import of renewable energy (50 percent). However, due to the Fukushima Event
in the year 2011, the targets that were previously set became difficult to achieve. A new fuel

Servo Motor System for Injection Moulding Machines
Servo Motor System a specific kind of fuel injection system supported by a moulding
machine that allows any motor to reduce the energy consumption while increasing the
mechanical efficiency. In conventional operation system, the injection moulding machine is
used to confirm that the open-loop dosing oil pump, asynchronous induction motors and other
motor systems are in fully functional condition. The operational procedure of the Injection
Moulding Machine similar to the traditional fuel injection, while the total energy
consumption becomes less during the time of powered on. This Injection moulding process
can be segmented into several stages that include high pressure clamping, melting plastic,
plastic injection, cooling, packing, mould and Thimble. In every phase of this process,
different amount of operating pressure and flow rates of fuel are required (Quan, Quan and
Zhang 2014). These operations are done in different settings. The majority of the available
injection system has fixed volume pump hydraulic system. The fixed volume system can
provide a constant rate irrespective of the situational requirement of fuel. In this system, the
surplus volume of hydraulic oil passes through the relief valve reflux in high pressure
throttling. It causes only 60 to 70 percent of energy efficiency. At the same time, full-speed
hydraulic oil circulation makes long term performance benefit for the machine by reducing
the resultant frictional force. It also blocks the excess leakage of energy due to noise and
frictional force. As a result, with better mechanical efficiency the machine consumes less
energy than usual (Peng, Wang and Wei 2014).

Infra-Red Heating System for Injection Moulding Machines
In industrial machinery, a huge amount of energy is consumed during the start-up
time. To make initial momentum and to reach the threshold temperature to perform
adequately the machine consumes a considerable amount of energy. Infra-Red heating system
preheat the machine to reduce the post ignition power consumption. It is also helpful for
domestic mechanical equipment that require huge power to start-up. In this system a Infra-red
gun is mounted with the fuel injection system either for petrochemical fuel or electrical.
Before starting up the ignition the Infra-Red gun throws Infra-Red ray to heat up the machine
before and during the ignition. An average consumption of a heavy electrical machine is
about 62.6 KW on regular basis. After the intervention of the Nano-electric heating the
consumption can be practically reduced to 38.8 KW. IF 26 days of operation is considered in
a month then the saving for this technology will be Q = (62.6-38.8) * 26 = 618.8KWH /
month (Oppelt et al. 2012).
Cloud server based energy management system
With the intervention of wireless network connection, the utility of Internet of things
has been increased significantly. This internet of things can be also utilised in the energy
management system for industrial, commercial and domestic use. In this system, a tracker is
attached to the electrical machine that tracks the electric consumption of the machine and
delivers the data to a dedicated server through real-time data sharing. User or the
administrator should have a user interface to access the dedicated server for energy
management. The user or administrator can view the current energy consumption in any
particular machine along with the temperature, operational efficiency and technical disputes.
Through this, the faults can be identified and the equipment can be repaired immediately

Sub-Metering
Sub-Metering technique enable a post billing automated auditing system that enable
the user to view the eclectic consumption comparison with a detailed assessment report. The
Sub-metering system works as a simultaneous data processing system mounted on the meter
gauge of any domestic or commercial meter box. The data processing of Sub-Metering does
not interfere the original meter reading or gauging procedure. It just makes a copy of the
generated output and executes several assessment programs to develop audit report. This
audit report can help the user to even verify the accuracy of the utility bills. It can be also
used to allocating energy cost to specific departments or tenets. One of the most helpful
point of utilising this technique is it helps to determine the required changes in energy
consuming systems to enhance energy efficiency (Fu et al. 2015).
Direct Alcohol Fuel Cell Technology
Fuel Cell technology has already made its place as a most effective and alternative
energy conservation system for future. The direct alcohol fuel cell is an additive enhancement
of this technology that marked a new way of sustainably future. A conventional fuel cell is an
electrical device that is capable to convert chemical energy to electrical energy. In
conventional fuel cell, pure hydrogen is used as fuel and operated below 100-degree Celsius
temperature. Here the challenge is the storage and distribution of the hydrogen as the fuel
through commercial market. Therefore, alternative fuel in fuel cell technology would be more
beneficial and tangible. Introducing the DAFC or Direct Alcohol Fuel Cell can allow the
technology to be more friendly for commercial trading. In near future this technology can be
without causing excess energy consumption. Sometimes this system can work as a plug and

in DAFC from renewable sources (Yan et al. 2012).
Collecting these elements from natural renewable resources can make this technology
very sustainable and eco-friendly. DAFC also operates in very low temperature and low heat
transition. 24 DAFC can be used with same heat energy required for a existing fuel-cell that
can increase the diversity of potential application. However, the major challenge is lo
affordability of this technology. Due to the high operating cost of Platinum-based catalysts
the resultant price can be boosted above the average expense capacity of people. In this
situation utilisation of non-platinum electro-catalysts and Nano-structured electro-catalysts
based on non-noble metals can be less costly (Corti and Gonzalez 2013).

Reduce the emission of the carbon dioxide by 2030 and at the same time making the
best effort to initiate early (Gao 2016).
Along with all these Nationally Determined Actions China also pledged to have it
defences placed against the climate risks like the coastal areas, cities, ecologically vulnerable
areas, water resources, water resources, forestry, agriculture. This has been done to
strengthen the emergency response systems, and the early warning system and the disaster
reduction and prevention mechanism. The Paris Agreement is framed into a simple
framework and it can be operationalised and understood for the community, business and
government. Target setting with the timelines will ensure a transparent metric for the tracking
results and everyone will work together for working together and summarising the Paris

One of the highlighting fact is that the Paris Agreement do not include the
International aviation and shipping. The issues pertaining to the climate change falls within
the purview of the International Maritime Organization and the Civil Aviation Respectively.
International Maritime Organization has mandated that the design of the new ships must have
a new design standards aimed towards the energy efficiency while the existing ships with the

Along with all these Nationally Determined Actions China also pledged to have it
defences placed against the climate risks like the coastal areas, cities, ecologically vulnerable
areas, water resources, water resources, forestry, agriculture. This has been done to
strengthen the emergency response systems, and the early warning system and the disaster
reduction and prevention mechanism. The Paris Agreement is framed into a simple
framework and it can be operationalised and understood for the community, business and
government. Target setting with the timelines will ensure a transparent metric for the tracking
results and everyone will work together for working together and summarising the Paris

International aviation and shipping
One of the highlighting fact is that the Paris Agreement do not include the
International aviation and shipping. The issues pertaining to the climate change falls within
the purview of the International Maritime Organization and the Civil Aviation Respectively.
International Maritime Organization has mandated that the design of the new ships must have
a new design standards aimed towards the energy efficiency while the existing ships with the
operational design standards (Larkin et al. 2018). Meetings conducted in the year 2016, made
it mandatory for the ships to both record and report the fuel consumption as the beginning

Chapter 5: Conclusion
From the above discussion it can be concluded that Energy Management
System Industry in Hong Kong is a high-speed growing sector. This sector is becoming the
important source of earning nationally. The energy management system is divided into three
categories, namely Domestic Energy Management, Industrial Energy Management and
Commercial Energy Management. Before investing on any specific energy management
policy and procedure the Hong Kong based business and industrial organisations should have
appropriate idea about the existing conditions, scopes of energy management programmes.
The research on energy management system can help the organisations to identify the most
suitable and profitable energy management procedure for them. As per the energy
consumption record of Hong Kong since 2007 the total energy consumption has been
increased significantly. However, the electrical energy consumption has been reduced from
52% to 47% compared with the other two energy sources. On the other hand, the oil
consumption has been increased by 6%. Instead of the decreasing rate of primary energy
requirements the final energy requirement has been increased since 2013. The total energy
consumption in domestic purpose is gradually increasing. However, the percentage share of
industrial electricity consumption is decreasing. At the same time, the commercial buildings
contribute to the total electricity consumption by 66.2%, which makes the total energy

also be used as a viable option. The hydrothermal carbonisation is a process which turns the
organic waste into a form of non-polluting form of bio coal that can be used as a fuel. This
bio coal can also be used to fertilise soil during the agriculture, bio coals can be used in the
chemical process which will produces plastics and it will also provide fuel for the coal fired
power stations. Even if Hong Kong achieves 100 percent transition to the renewable energy,
still Hong Kong will be unable to achieve self-sufficiency and it would mean that the Hong
Kong has to import electricity from the China or other countries (Lu, Jordan and Berge

Hong Kong does not have its own oil fields still it imports oil from other countries.
Like the same way, solar power can also be brought from Australia or Gobi Desert. This can
be made easier because the electricity transmission and storage uses improved technology.
Biofuels are also the other viable options but this will depend on the development of an
electric transport system. The climate action plan for the year 2030 of Hong Kong has
revealed that the renewable energy will only provide 3 to 4 percent of the energy mix as the
current scenario only provides 1 percent of contribution. Hong Kong has implemented the

that Hong Kong is located is located in the sub tropics and the city receives significant
amount of solar flux. It has been measured that in average the global horizontal radiation is
1.29 MWh/m2. There are several studies that have indicated that fact that potential for the
generation of electricity is through the solar water heating and solar photovoltaics in the city.
While it has been estimated that the Hong Kong has the potential for 6 GW of rooftop PV and
this could approximately lead to the generation of 6000 GWh electricity annually. This huge
amount of energy would be sufficient to fulfil the demand of 14 percent of the Household
which is compared with consumption of 43,912 GWh of electricity (Ma, Yang and Lu 2013).
There are other studies that have confirmed that the rooftop PV can generate about 1660
GWh/year and this percentage is about 6 percent of Hong Kong’s entire energy demand.
Furthermore, consultation studies along with the Hong Kong government have proved that
there is a potential of 5944 GWh/year and it includes the open spaces, airports, railways,
roads and rooftops (scmp.com 2019). In Hong Kong the solar water heating and the
production of hot water accounts to 4 percent of the total energy usage in Hong Kong. The
estimation also includes the liquefied petroleum gas, electricity, and town gas (produced from

lead to the production of 2630 GWh of electricity annually and it will meet 6 percent of the
Hong Kong’s electricity demand. Wind turbines can also be installed on the rooftops of the
buildings and it is even estimated that 3000 GWH/year of the electricity can be generated.
Offshore winds also have significant potential for Hong Kong energy generation because 60
percent of the total area is covered by sea and the wind resources are higher for the sea in
comparison to the land. It has been estimated that the 7688 wind turbines can be installed in

Energy Audit will be carried out for the monitoring the historic and the ongoing energy use
for the buildings. It will serve as an important step towards improving energy performance
and identifying the opportunities. The different aspects of the energy audit will include the
data collection, site survey and measurement, and benchmark. The energy audit for the
buildings leads to the identification of the energy management opportunities. It provides a
baseline data which is used in the implementation of the energy management opportunities
and a comparison can be made overtime (Krarti 2016). The different aspects of an energy
audit include: data collection defines how the gathering of information regarding the where,
how and when the energy will be used in the evaluation of the building energy performance.
This information will be collected from the meter buildings and the energy bills. Site survey
and measurement is a detailed action plan which will provide a present scenario of the energy

be identified after the analysing the measured data (Ee.emsd.gov.hk 2019). Benchmark and
the indicators are the vital tools for managing energy usage that corresponds to the type of the
building. Through benchmarking the performances of the similar facilities are analysed and
the energy performance is measured. Benchmarking is an important step because through
benchmarking the deficiency in the present energy management practices can be identified.
Formulation of the action plans will be based on the results gathered from the energy audit
and the energy management opportunities will be implemented to ensure a systematic
process. The plan of action must contain the budgetary requirements, funding requirements
and an implementation table (Coakley, Raftery and Keane 2014). Implementation of the
action plan and the progress of its implementation is needed to be implemented to ensure the
desired energy target within the specific timeframe. The top down approach is followed so
that the action required for the active participation is carried out smoothly. Evaluation of the
reduction targets and the organization of the management resources (Missaoui et al. 2014).
Energy Audit will be carried out for the monitoring the historic and the ongoing energy use
for the buildings. It will serve as an important step towards improving energy performance
and identifying the opportunities. The different aspects of the energy audit will include the
data collection, site survey and measurement, and benchmark. The energy audit for the
buildings leads to the identification of the energy management opportunities. It provides a
baseline data which is used in the implementation of the energy management opportunities
and a comparison can be made overtime (Krarti 2016). The different aspects of an energy
audit include: data collection defines how the gathering of information regarding the where,
how and when the energy will be used in the evaluation of the building energy performance.
This information will be collected from the meter buildings and the energy bills. Site survey
and measurement is a detailed action plan which will provide a present scenario of the energy
usage. The site survey and measurement will provide the means of improvement which will
be identified after the analysing the measured data (Ee.emsd.gov.hk 2019). Benchmark and
