Energy management
• Energy management activities consists of monitoring energy
consumption, analysing trends in energy use, identifying and
implementing energy saving measures, and verifying savings with
proper measurements.
• Energy management helps managers and staff to identify options for
increasing energy efficiency, carry out energy efficiency projects,
monitor energy use and results, and learn from technical actions.
• It is widely accepted that only systematic energy review and
management process can tap the full potential of energy efficiency
in industry
2
Barriers to implement Energy Management (EM) in industry
• Policies: There are no mandatory rules or regulations to adopt EM or reduce GHG emissions
• Market conditions: The prices of fuels and electricity are low; no CO2 market; or no market recognition
• Lack of information: Enterprises do not recognize the need where and how spend energy
• Technical: Enterprise are unable to monitor their energy use or/to modify their processes
Benefits of EM
• Organization’s financial savings
• Increasing of reliability of operations
• Positive effect on productivity and competitiveness
• Attractive financial and economic returns
• Reducing the exposure to rising energy prices
• Increasing of security of supply
• Reducing the impact on the environment
4
Why it is not happening?
• Management focus on production, not on EM
• Lack of information and understanding of financial and
qualitative benefits
• Lack of adequate technical skills for identifying, developing and
implementing EE measures and projects
• Poor monitoring systems and data
• First costs more important than recurring costs > disconnection
between capital and operating budgets
• When EM knowledge exists it very often resides with individuals
rather than with the company/ organization > sustainability risk
• Financing
5
Energy Management System (EnMS) • An energy management system (EnMS) is a collection of procedures and practices to
ensure the systematic tracking, analysis and planning of energy use
• Structured approach to the management of energy use
Energy Management System Standard
• Standardised approach to implementing an EnMS
• Best practice EM standard refers to a management system that meets
the requirements of ISO 50001:2018
• An organization may decide to base its EnMS on a standard e.g. ISO 50001:2011
Certification of EnMS
• An organization may decide to have its EnMS certified (to demonstrate its
best practice to customers, clients and suppliers OR fulfil a legal or other
requirement)
6
• Energy management programmes (EnMP) are the policies and
initiatives that encourage companies to adopt energy management
systems. Energy management programmes play an important role
in showing that improving energy efficiency is not only compatible
with – but can also drive – profitable business development.
• Energy Management System (EMS) refers to a software that
enables energy optimization by use of temperature setbacks,
occupancy controls, or other control functions
7
What EnMS can achieve
• Systematic activity
• Actively managing energy use and costs, reducing
exposure to rising energy costs
• Obligation to train and raise awareness
• Obligation to provide resources
• Document savings for internal and external use (e.g.
emission credits, legal reporting requirements)
• Reduce GHG emissions without negative effect on
operations
• Continuity through changes of personnel

Management/Technical Interaction
To certify or not ?
• Certification by an independent auditor is
not a requirement of the standard itself
• To certify or not is a decision to be taken by the
standard user, unless imposed by regulatory
requirements.
EnMS
Based on the concept of:
• Plan
• Do
• Check
• Act
Management Responsibility
• ISO 50001 Standard says……
– It requires the top management to demonstrate
its commitment to support and continually
improve the effectiveness of the EnMS
Management Responsibility
• Is the top management really
comitted?
• Will they support the
system?
• This is a decision point!
• If not, we can all go for
coffee now!
• Will they make the necessary
resources available (technical,
financial and human)
• Management Give commitment
• Sign policy
• Allocate resources
• Assign responsibility
• Top management representative
• Give support
• Make decisions
Management Role
The foundation of the system
Management Support & Commitment
• Top management commitment is crucial to the successful
implementation of the EnMS.
– provide the necessary resources such as time, personnel,
financial, materials, etc. for the effective implementation
of the EnMS.
• It must be communicated and made visible to the entire
organization to encourage active participation of all staff
members in adhering to the EnMS.
Management Representative
• ISO 50001 Standard says……
– It requires the top management to appoint a
management representative(s) to promote
awareness and oversee the implementation of the
EnMS. (Item 4.2.2)
MR
• ISO 50001 standard requires an organization to appoint a
management representative to oversee the development and
operation of the EnMS.
– To help the organization achieve its energy objectives and
targets and for improving energy performance.
• Should be competent to perform the required duties and be
capable of exerting influence throughout the organization to
implement and improve the EnMS.
MR Roles
• Responsible for managing all aspects of the
EnMS as it evolves.
• MR should have sufficient authority,
competency and resources to ensure the
overall effectiveness of the EnMS.
Energy Manager • In some organisations, this may be the same person as the
management representative
• Often not a full time job;
– For example, maintenance or engineering manager or engineer
– Probably a technical person with energy engineering knowledge
• Role
• Implement the EnMS
• Owns the EnMS
• Manages energy use
• Acts as auditee for the EnMS
• Responsibility
• Varies with organisation
• Implementation
• Energy budget
• Reporting
Energy Management Team
• The energy management team is responsible for
ensuring the implementation of actions/measures of the
energy management decisions.
• The composition and size of the energy management
team should be determined with due consideration of
the size and complexity of the organization.
Energy Management Team
• Decide structure and membership based on size and
complexity of your organisation
• Representatives from relevant departments
– Production, finance, engineering, operations, senior
management representative, energy manager or
engineer, etc.
• Cross functional cooperation
• Common and shared goal
SUSTAINABLE
TEAM
Roles, Responsibility & Authority
• Required for each individual involved in the EnMS
• Each person needs to understand their own role and
responsibilities
• Every needs to know each others authority levels
• This may seem like common sense but is
often a source of ineffectiveness
• MUST be completed, accepted and communicated in
advance of next steps
Energy Policy
• ISO 50001 Standard says……
– It requires the organization to define an energy
policy to state its commitment for achieving energy
performance improvement. (Item 4.3)
Energy Policy
• Management commitment
• Not just a signature!
• Define scope of EnMS
• Appropriate to scale
• Commitment to continual improvement
• Make resources available
• Framework for target setting and management
review
Energy Policy • ISO 50001 requires an organization to at least state the
following
commitments in the energy policy:
– Continual improvement in energy performance;
– Availability of information and of necessary resources to
achieve
objectives and targets;
– Compliance with relevant legislation and other
requirements related to
energy use, consumption and efficiency;
– Support for purchasing energy efficient products and
services; and
– Designing for enhanced energy performance.
Energy Policy
• The policy should be defined and approved by the top
management to show its commitment to meet the
organization’s goals.
• Must be communicated to all staff and be reviewed and
updated in a systematic manner.
• The organization can decide whether or not to make the
policy available externally.
Energy Policy
Barriers to success
• Common weaknesses in energy policies that lead to
poor energy management:
– not actively supported by senior management
– not succinct
– lack of specific targets and commitments
– out of date – not a living document
– not supported by a strategy with the ability to deliver.
Energy Planning
Planning • How much energy am I using?
• Where am I using it?
• Which are significant users?
• What is driving it?
• Who is influencing its use?
• Do I need to have an energy
assessment (=audit)?
– If yes, focus it
• System Optimization
• Renewable energy options
• Are there legal or other requirements?
• Develop baselines & EnPIs
• Set objectives and targets
• Action Plan
Overview of Energy Planning Process
Electricity Laws & Regulations:
• ‘Energy Commission Act’ (2001) empowers the EC to advise the Minister
on energy supply activities (which is defined as electricity and piped
gas). The remit of the Act includes regulation on transmission,
generation, safety and promotion of renewable energy.
• ‘Electricity Supply Act’ (1990) to provide for the regulation of the electricity
supply industry from generation, transmission in respect to safety of persons and efficiency use of electricity.
• ‘Electricity Supply Regulations’ (1994) under the provisions of the Electricity Supply Act (ESA), registers electrical installation, competent persons in the electrical industry, contractors, and provide a list of electrical equipment which are safe and can be used in Malaysia. Under this regulation, energy labeling of electrical equipment are also included.
• ‘Efficient Management of Electrical Energy Regulations’ (2008)
becomes operation on 15th December 2008 and make it mandatory
of installation to appoint energy managers and submit energy audits.
Energy Review, Baseline & Performance Indicators
• ISO 50001 Standard says……
– It requires the organization to develop, record and
maintain an energy review as well as document the
methodology and criteria used to develop the review.
(Item 4.4.3)
– It requires the organization to establish an energy
baseline(s) for the
measurement of the energy performance. (Item
4.4.4)
– It requires the organization to identify appropriate
energy performance
indicators to monitor and measure its energy
performance. (Item 4.4.5)
Energy Review
• The organization must record and maintain an energy review with certain
documented methodology and criteria.
• An energy review is a process to determine an organization’s energy
performance based on
• data and/or actual measurement, leading to identification of
opportunities for improvement.
• The review provides useful information for the development of the
energy baseline and the selection of energy performance indicators
(EnPIs).
• It also establishes the monitoring capability to support effective
continuous improvement of the EnMS in the future.
• Energy Review is Energy Audit
Energy Audit
• Energy audits are a tool to reduce energy consumption and
find a long-term solutions.
• Identify and prioritize opportunities to improve energy
performance, reduce energy waste and obtain related
environmental benefits.
• Audit outputs include
– information on current energy use and performance
– recommendations for improvements in a wide range of
areas, covering
• operational controls,
• maintenance controls,
• modifications and
• capital projects.
Significant Energy Users (SEUs)
Which systems?
• Sub meters
• Motor list
• Estimation
• Calculation • Pie Charts • Sankey
Diagrams
Which
people?
• Who influences SEUs?
• Training needs
• Organisation charts
Drivers?
• What is driving use?
• Variables
• Activity
• Weather • Regression
analysis
How to quantify each energy user?
• Do you have sub-metering?
• This is the best situation
• Ideally automatically logged to a database
• Manually read also gives good information
• Are meters accurate and working
• Is data collection working and accurate
• Do you have local meters?
• kW, A, flow rate, etc.
• These can be read manually and
calculated/estimated
• Care with time of readings
• Quantification or estimation of use
• Equipment List and energy information
(specifications/actual data)
Which systems?
• What is the single largest energy user in
your organisation?
• How much energy does it use?
• What drives that use?
– What causes it to increase or decrease?
• Which people affect the energy use of that
item/system?
Determination of Energy Consumption
• Analysis of Energy Bills
• Energy Measurements
• Energy Estimation
– When actual measurement of data is not available,
estimation of monthly energy consumption by power
rating and operating hours may be adopted
Heat Balance • Use what you know:
• Steam flow
• Feedwater flow (= steam flow approximately)
• Fuel flow (heat flow = fuel flow * efficiency)
• Gas bills
• Hot water flow and temperature difference (dT)
(Q=m*Cp*dT)
• Build up a balance
• Heat in = heat out
• If you have a significant gap, you may need to measure it
• Ultrasonic flowmeters, portable heat meters
• More challenging than electrical power
– Typically fewer measuring points
Establish energy performance indicators (EnPIs)
• Varying levels of complexity
• Absolute energy consumption – Simple but ignores activity levels
• Simple Ratios – Easy to use but can be
• misleading – Take account of activity levels
– Can only deal with single variables
• Regression analysis
– More complex
– Quantifies driver effects
– Allows comparison of
actual
against expected use
• Try to have an EnPI for
each
SEU
Energy Performance Indicators (EnPI)
• Energy Performance Indicators (EnPls) to
monitor and measure energy performance.
• EnPIs are useful tools to enable
management to assess actual energy
performance against expected outcomes.
• An EnPI can be a simple parameter, a
simple ratio or a complex model.
EnPI • The organization can select and determine suitable
EnPIs according to the operation to better reflect and
measure its energy performance.
• The EnPIs should be updated when business activities
or baselines change that affect their relevance.
• The methodology to determine and update the
EnPIs should be recorded and reviewed regularly.
EnPI
• energy consumption per unit of floor area
• energy consumption per unit of production
• Y = mX + C
• Y = m1X1 + m2X2 ….. + C
• Where are we starting from?
• Permits quantification of success (or failure!)
• Different types:
• Absolute consumption
• Specific energy consumption, e.g. kWh/unit
output
• Regression formula
Energy Baseline(s)
Baselines • Baseline is initial model
Baselines
Energy Metrics
• Consider the drivers for each SEU
• This relationship may be your baseline
• Energy Performance Indicators (EnPI)
• Baseline
• Baseload
• Regression Analysis
Measurement Plan
• Once SEUs are known
• Including variables
• Reporting requirements can be specified
• What meters and measurements are required to deliver these reports?
• How much can be achieved with existing instruments?
• Manual vs. automated
• List what new instruments are required
• Each new instrument should be able to justify its cost
• Don’t forget installation cost
• Electricity and liquid flow meters can be good value
• Gas flow meters tend to be expensive (steam, compressed air, etc)
System Optimisation
• Examine the whole system and not individual
components
• Establish user requirements and specification
• Examine opportunities with use
• Examine opportunities with distribution.
Opportunity List
Types of people who impact energy consumption
• Immediate and direct impact
• SEU Operators
• Maintenance and external service personnel
• Influencers
• Managers, supervisors, leaders
• Production people
• People who see things differently
• Cleaners
• Security
• Safety Officers
Energy Management System Planning Outputs
• Energy
Baseline(s)
• EnPIs
• Objectives

• Action Plan
Objectives, targets & action Plans
• ISO 50001 Standard says……
– It requires the organization to establish, implement and
maintain documented energy objectives, targets and
action plans specified outcome or achievement defined
to meet its energy policy related to improved energy
performance. (Item 4.4.6)
Objectives & Targets
• Documented energy objectives and targets should be
established to ensure compliance with the organization’s
energy policy, and to facilitate continual improvement in
energy performance.
• Objectives should state what the organization wants to
achieve; while targets should specify how the organization
would achieve those objectives.
• The objectives and targets should be practical, achievable
and measurable, and must conform to the organization’s
business objectives and preferably provide some challenge
to the organization.
Objectives & Targets

Action Plans • Action plans should be developed to address all of the
organization’s energy objectives and targets detailing how
and when they are to be achieved, which will subsequently
facilitate monitoring the progress in achieving the energy
objectives and targets.
• The action plans should include schedules, resources and
responsibilities for achieving the objectives and targets.
• They should be flexible and be able to be revised to reflect
any changes in the objectives and targets.
Example of an Action Plan
• Replace lighting with more energy efficient options
• Provide energy training for staff
• Ensure air handling units are turned off when not
required
• Review and upgrade if required insulation
• Substitute high efficiency motors when replacement is
required.
• Use ambient air for compressed air system intake.

persons related to significant energy uses are
competent. (Item 4.5.2)
Competence
• Competence refers to persons who possess the required skills,
knowledge, qualifications, and capacity to perform their duties that
can significantly affect energy use or the implementation of the
EnMS.
• A competent workforce is essential in successfully implementing the
organization’s EnMS and achieving improved energy performance.
• The knowledge and skills that are necessary to implement the EnMS,
ensure control of the significant energy uses and achieve the energy
objectives and targets must be addressed.
Training • Appropriate training should be provided to all relevant personnel.
• This training should include general concept of energy management as well as
skills training (usually on-the-job) to allow personnel to carry out their tasks with
an awareness of the impact their activities can have on the energy
performance.
• Contractors working within the boundary of the organization, should be required
to provide
details of their competence
Communications
• ISO 50001 Standard says……
– It requires the organization to address internal
communication in relation to its energy performance
and EnMS. The organization should also decide
whether to communicate externally about its energy
policy, EnMS and energy performance. (Item 4.5.3)
Internal Communication
• An internal communication procedure could include how
staff members are made aware of energy issues, how
decisions are made or information is disseminated to staff
etc.
• make provision for the communication of suggestions /
complains etc.
relevant to energy management and how these are dealt
with.
• Communication procedure to cover the process in
responding to comments and suggestions by contractors
working for or on behalf of the organization.
External Communication
• Should maintain a documented decision on whether it will
communicate its
energy policy, EnMS and energy performance externally
• If they do, they should consider the following aspects:
– type and level of information to be communicated;
– targets of communication;
– mechanisms and responsible parties to handle and
respond to enquiries;
– official response time; and
– recording system and format of communication and the
associated correspondence.
Documentation
• ISO 50001 Standard says……
– It requires the organization to establish, implement
and maintain information to describe the core
elements of the EnMS and their interaction. (Item
4.5.4.1)

4.5.4.2)
Documentation • ISO 50001 Standard require documented information that describes
the core
elements of their EnMS:
– scope and boundaries of the system;
– energy policy;
– energy planning process including methodology and
criteria used to develop the energy review, energy
baselines and methodology for determining and
updating the EnPIs;
– energy objectives, targets and action plans; and
– decision whether to communicate externally about information of
energy
performance.
Operational Controls
• ISO 50001 Standard says……
– It requires the organization to identify and plan operations and
maintenance activities which are related to its significant energy
uses in order to ensure that they are carried out under specified
conditions. (Item 4.5.5)
Operational Controls
• Implementation of the EnMS is dependent on the
establishment and maintenance of operational
procedures and controls to ensure that the
significant energy uses are being controlled
• Review all significant energy uses to identify those which
are not already controlled or where existing controls may
be insufficient, and to subsequently ensure that control
procedures are in place for all such areas
Review Operation Control
• This is aligned with the review of training needs
– It additionally checks operating and maintenance procedures
• Check operating procedures
• Are operators familiar with the energy impact of operations?
• Check maintenance procedures
• Check maintenance frequencies
• Are maintenance staff familiar with the energy impact of their work?
• This review will help to assess training needs
Operational Control: A critical element of the EnMS for energy savings

contribute to business competitiveness and raise productivity,
energy efficiency actions and improvements are still not typically
or widely viewed as a strategic investment in future profitability.
• Because energy efficiency potentials are highly fragmented and
spread across a multitude of locations and devices, this dispersion
ensures that energy efficiency is the highest priority for virtually
no one.
• EnMPs are a means of encouraging the use of EnMS to overcome
a range of barriers
109
Energy management Programme (EnMP)
EnMPs help companies to the implementation of EnMSs, and
provide guidance and support for the implementation process.
110
Drivers and Supportive policy mechanisms for EnMS
implementation
• Target-setting agreements (incl. reporting requirements)
• Tax policies
• Subsidies for energy audits
• Training and technical assistance
• Recognition programs Reward programme and other forms of
recognition
111
• Capacity-building for EnMS implementation
• Conformity assessment professionals
• Mandatory implementation of EnMS
• Energy review, benchmarking and technical tools.
• Case studies showing peer experience.
• Guidance materials.
• Workshops, networks and other fora for best practice exchange.
112
Target-setting
• Mandatory: Where adoption is made mandatory within the
goal of achieving a certain energy intensity target
• Voluntary or negotiated agreements: used by governments as a
mechanism for promoting IEE
Challenges
• Sectorial targets are divided across facilities
• Need for robust mechanisms for target setting
• Government enforcement and control agencies have capacities
• Need for institutional capacities from industries (associations,
chambers, federations) to negotiate and operate
113
Tax policies and incentives
• Exemptions to enterprise taxes:
– On fuel or electricity use
– On carbon taxes
• Rebates on VAT of efficient industrial equipment or
monitoring systems for environmental and/or energy control
• Reduced income tax
Challenges
• Can be perceived as a subsidy
• Enterprises ability to use the instruments
114
Training and technical assistance
• Government led or government funded programs to strengthen technical
skills in the industrial sector
• Subsidizing technical consultants who may assist the implementation of
EnMS
Challenges
• Encouraging industry to participate
• Can be perceived as a subsidy
• Enterprises ability to use the instruments
• Availability of qualified staff
• Creation of qualification mechanisms for technical experts
115
Enterprise Recognition Programs
• Market based policy > to achieve recognition there has to be a
tangible benefit obtained by the recognized enterprises
• Third party verification > to provide industrial facilities and
companies with a transparent system for verifying improvements
in energy performance and management practices, which may
involve or not ISO certification
• Can be supported by cost-shared training and technical assistance
for facilities seeking
Challenges
• Enterprises ability to use the instruments
• Market value
116
Capacity-building for EnMS
implementation
• There is a need to have responsible agencies and competent
staff across all aspects of an EnMS promotion policy, whether
there is mandatory enforcement or control or just promotion of
EnMS
• Need for inter-institutional coordination
• How to equip government agencies with mandatory roles?
• How to strengthen agencies with support roles?
Challenges
• Need for dedicated teams or agencies?
• Enterprises ability to use the instruments
117
Capacity-Building for conformity assessment professionals
• If enterprises will certify the ISO 50001 standard, then the
Quality Infrastructure needs to strengthened, particularly the
ability of Certification Bodies to assess conformity, starting by
Auditors
• There are three main features of certification bodies that are
addressed relative to conformity assessment, competency,
consistency, and impartiality
• Need for an internationally recognized
• accreditation process at country level
Challenges
• Ensuring that energy performance improvements are achieved
118
• Discuss with your friends about environmental effects
from application of coal, oil and gas (3-5 minutes).
• Give your opinions on:
– Power generation sources in Malaysia or in your country
– What are the environmental impacts from these fossil fuel
uses?
– Per capita emission in Malaysia and world?
– How could the impacts be minimized?
– Do you think Malaysian power sector is sustainable?
