Energy in Science:
“Energy is something that can do work”.
“Energy is a source of power such as fuels”. (Oxford)
There are two basic forms of energy:
• Kinetic Energy
• Potential Energy
Conservation of Energy:
When energy changes from one form to another, the amount of
energy stays the same. Energy cannot be made or destroyed. This
rule is called the "conservation law of energy".

performance, raising operational efficiencies and greening their brand.
• GHG EMISSIONS AND CLIMATE CHANGE:
The ISO 50001 Standard shall lead to reductions in GHG emissions and other future
Environmental impacts of climate change, through the systematic management of
energy.
• ACID RAIN:
Acid rain = SO2 (Sulphur dioxide) + NO (Nitrogen Oxide) + H2O (Water)
The reduction of these emissions through better energy management will mitigate
harmful impacts of Acid Rain.
18. 18
• AIR QUALITY:
Beside greenhouse gases, SO2 and NOx emissions that cause acid rain, emissions of
particulate matter contribute to bad air quality. Fuel combustion is the most important
source of anthropogenic nitrogen oxide. Energy performance improvement will lead to
Air Quality Improvement.
• WATER QUALITY:
Damage caused by the exploration and transport of oil is related to the pollution of
the water. By better management of Energy sources water quality will be improved.
• Helps in meeting International GHG reduction targets

• Action plans- formulating action plans to achieve objectives and targets, legal/ regulations
and other requirements and shall include:
• designation of responsibility.
• The means and time frame by which individual targets are to be achieved.
• A statement of the method by which an improvement in energy performance shall be
verified.
• A statement of the method of verifying the results.
34
35. Source: ISO 50001 Standard
For Assessment documentation shall include seasonal and annual records of metered electricity,
natural gas or other fuel used for stationary equipment. A list of proposed energy saving activities
and anticipated energy savings due to conservation actions or equipment modifications are also
required. The producer should consider activities to reduce energy usage for items such as:
• Lights & Fans
• Stationary Engines
• Production Machinery
• Pumps , vacuum pumps
• HVAC
• Refrigeration
• Miscellaneous
35
Energy Baseline:
Quantitative reference(s) providing a basis for comparison of energy performance
NOTE 1 An energy baseline reflects a specified period of time.
NOTE 2 An energy baseline can be normalized using variables which affect energy use and/or consumption, e.g.
production level, degree days (outdoor temperature), etc.
NOTE 3 The energy baseline is also used for calculation of energy savings, as a reference before and after
implementation of energy performance improvement actions.
36. 36
Record Keeping for Energy Baseline:
It is the responsibility of the producer, to maintain records which document energy use. Records
include:
• Utility and/or fuel purchase bills
• Quantities and sources of energy applied;
• Dates (month and year) documenting energy use.
• Methods of energy use
• Actions taken to improve energy efficiency
• Removal or addition of energy use components
37. EnPIs:
It is now common practice to use Key Performance Indicators (KPIs) to summarize volumes of
data into a few critical “nuggets” of actionable information. These KPIs provide both the metrics
that will be used to determine the success of a business plan as well as the timely information
managers need to track performance and make adjustments to ensure success.
A similar approach can be used in the practice of energy management, where KPIs can be
designed as EnPIs to measure the success of key elements in an energy management plan and
provide energy managers with the timely “nuggets” of information they need to ensure success.
Examples may include:
• Total Energy Use
• Energy Composition
• Usage by Energy Source
• Unit Energy Costs
• Total Energy Costs
• Excluding Cooling
• Stage of Production and Plant Services
37
38. EnPIs serve as performance rating systems to allow for comparison against similar
facilities. Benchmarking can be done in variety of ways. Facility or organizational
performance may be benchmarked to:
• Past performance — A comparison of current versus historical performance.
• Industry average — Based on an established performance metric, such as the recognized
average performance of a peer group.
• Best in class — Benchmarking against the best in the industry and not the average.
• Best Practices — A qualitative comparison against certain, established practices considered
to be the best in the industry.
The key steps in benchmarking include:
• Determine the level of benchmarking ( for example: equipment, process line, facility or
organizational).
• Develop metrics.
• Conduct comparisons.
• Track performance over time
38
40. 40
Collect data:
• The data must be complete and accurate because it will be used for analysis and goal
setting. Consider the following when collecting energy use data:
• Determine appropriate level of detail : Some may choose to collect data from sub-meters
on individual processes while others may only look at a utility bill.
• Account for all energy sources: Inventory all energy purchased and generated on-site
(electricity, gas, steam, waste fuels) in physical units (kWh, mMBtu, Mcf, lbs of steam, etc.)
and on a cost basis.
• Document all energy uses: For the sources identified above, assemble energy bills, meter
readings, and other use data.
• Gather at least two years of monthly data or a more frequent interval if available. Use the
most recent data available.
• Collect facility and operational data . it may be necessary to collect non-energy related
data for all facilities and operations, such as building size, operating hours, etc.
43. • IMPLEMENTATION AND OPERATION
• Organization to use the action plans and other outputs resulting from the planning process
for implementation and operations and would require:
• Competence, training and awareness of work force on their role, responsibilities and duties.
• Communicate internally with workforce on energy performance, EnMS and establish a
process through which suggestions can be invited to improve EnMS.
• Records and document of the implementation and operation of the EnMS scope and
boundaries, energy policy , objectives , targets, action plan and other documents as required.
• Operational Controls of those operation and maintenance activities related to significant use
of energy.
• Design of new, modified and renovated facilities, equipment, systems and processes that can
have a significant impact on energy performance.
• Procurement of energy efficient products, services and energy.
.
43
46. • MONITORING ,MEASUREMENT AND ANALYSIS

measured and analysed at planned intervals:
• Significant energy uses and other outputs.
• Energy Performance Indicators (EnPIs).
• Effectiveness of Action plans.
• Energy measurement plan.
• CORRECTIVE AND PREVENTIVE ACTIONS
• CONTROL OF RECORDS
46
47. • INTERNAL AUDIT
• Conduct internal audits to ensure that Energy Management System (EnMS) confirms to:
• Planned arrangements for energy management .
• Energy objectives and targets established.
• Effective implementation.
• EVALUATION OF COMPLIANCE
• Legal Requirements.
• Other Requirements.
47
49. • MANAGEMENT REVIEW

51. EnMS CONCLUSIONS
• A new international ISO 50001 standard, applicable to any organization whatever
the size, industry or geographical location, will benchmark energy management,
and establish a framework for organization to manage energy use efficiently.
• It is estimated that the standard could influence up to 60 percent of the world’s
energy use.
• This International Standard is based on the Plan-Do-Check-Act continual
improvement framework and incorporates energy management in organization
practices.
• It does not establish absolute requirements for energy performance beyond
the commitments in the energy policy of the organization and its obligation to
comply with relevant legislation.
51
52. EnMS CONCLUSIONS
• Developing Best Practice Guides on sector specific energy conservation
technologies and methodologies will facilitate the implementation of ISO 50001.
• ISO 50001 is designed to be used independently, but can be aligned or integrated
with other management systems (e.g., ISO 9001 and 14001).
• ISO 50001 will be a voluntary system, but may tend to become de facto essential
requirement as rapid uptake by competitors will drive non-participating
organizations to adopt it as well.
• An organization embracing ISO 50001 is likely to further accelerate adoption of
energy efficiency practices and to continuously improve its energy performance
and cost.
