2. EnMS for Improving Energy Performance
A. What is EnMS?:The Essence /Architecture of EnMS
B. How to EnMS?: The Knowhow on Implementation
C. Why to EnMS?: The Business Case

3. Essence
EnMS is a set of systems and processes to
improve energy performance of enterprises
Architecture
EnMS is Plan-Do-Check-Act (PDAC) framework,
as for all ISO standards, providing a systematic
approach for enterprises to set & achieve targets
and plans for energy performance improvement

4.  Set of interrelated or interacting elements to
establish an energy policy and energy
objectives, and processes and procedures to
achieve those objectives.
 Purpose of ISO-50001 is to enable organizations to
establish the systems and processes necessary to
improve energy performance, including energy
efficiency, use and consumption.
Note: ISO-50001does not lay down minimum absolute
performance but leaves with the organization to decide. It
stresses on management of continual improvement.

5.  O: Organize (Cl. 4.1 to 4.3) (Assuming commitment from top MGMT)
 Formulate Energy Policy
 Appoint MGMT Rep (MR)
 Constitute Energy MGMT Team
 Allocate resources
 Finalize scope & boundary of EnMS
 P: Plan (Cl. 4.4)
 Finalize energy planning process
 Identify legal & other requirements
 Develop Energy Review highlighting significant energy use and list
of improvement opportunities
 Determine energy baseline and identify appropriate EnPIs
 Finalize energy objectives and targets consistent with energy policy
and its business conditions
 Finalize Energy Management Action Plan s for achieving objectives
and targets

6.  I: Implement (Cl. 4.5)
 Build capacity and competence through training & awareness programs and
communication policy
 Describe and document the core elements of the EnMS and their interaction
 Identify O&M activities related to SEUs so that these are carried out under
specified conditions
 Set criteria for effective O&M activities for SEUs and put them in place
 Set energy performance criteria for design and procurement activities
 E: Evaluate/Check (Cl. 4.6)
 Systems for Monitoring, Measuring and analyzing energy uses and key
characteristics of operations to include EMIS, M&T and savings M&V
 Compliance with legal and other requirements
 Internal audit of the EnMS
 M: Management Review (Cl. 4.7)

9. Step by Step Guide
On
EnMS Implementation
(Clues on EnMS Planning only)

10.  Engage an EnMS consultant with defined and
scalable scope of work
 Decide Boundary and Scope of EnMS
 Appoint Management Representative (MR)
 Organize Energy Team
 Formulate Energy Policy
 Identify individuals whose activities influence
energy use and consumption

11.  Management Representative (MR) can be an
existing employee in fairly senior level to
handle MR job as additional responsibility.
 Or he can be a new recruit having requisite
competence to handle the job. He can be a
full time/part time contract employee with
adequate authority over functional areas.
 Energy Team (ET), to be headed by MR, shall
have persons form all functional areas.

12. Essential Points to be covered in Energy Policy
 The Business/Industry of the organization
 The commitment of the top management for
continual improvement in EnMS and energy
performance
 Commitment of the organization for specific
% improvement in energy consumption over a
specified period
 Commitment of the organization to allocate
resources to achieve objectives/targets

13. Approved Energy Manual can reduce decision
making process and help to achieve continual
improvement in energy performance & EnMS.
The Energy Manual may include:-
 Scope & Boundaries of EnMS
 Energy Team and its functions and authority
 Energy Policy
 Guidance on planning process
 Guidance on training and awareness programs
 Core Elements of EnMS
 Key Documents in EnMS
 Any other procedural matter as necessary

14.  Develop & document energy planning process
 Identify legal & other requirements
 Develop & record Energy Review
 Establish Energy Baseline
 Identify EnPIs
 Establish energy objectives and targets
 Establish EM action plans

15.  Review the organization’s activities and identify
people affecting energy performance & consumption
 Define methodology for energy review
 Review availability of monitoring & control systems
 List out the data to be collected for energy review
 Define the forms & formats of data
 Identify the sources of data, when & wherefrom
 Lay down a method to check the accuracy of data
 Plan to receive & store the data for later analysis
 Check functioning of above process
 Check if anything missing

16. Following data are generally required
 Area and details of Facility/Plant Building
 Utility Billing Data
 Utility Interval Data
 Utility Tariff & Rules
 Production Figures
 Process Flow Chart
 Operating Schedules
 Monitoring and control systems
 Rated Power(KW/HP) of major equipment
 Measured Data with portable instruments for
individual systems/equipment/process
 Financial Data

17. SEU List (All consumption to be in same units)
Item Percentage of Total Consumption
 Boilers --- %
 Process Motors ---%
 Air Compressors ---%
 Chillers/AHUs ---%
 Lighting ---%
 Others ---%
As O&M personnel can affect SEUs, list them as well as
the factors that can influence the SEUs
Note:-SEU Listing is iterative process starting from using rated
power & operating hours data. Then it is refined through energy
balancing exercise by using the portable power meters to
measure power and to correct figures.
Energy Baseline is determined from above data

18. General Criteria for Prioritizing
 Amount of annual savings in energy cost
 Amount of investment required
 Payback of EM Measures
 Time required for implementation
 Impact on safety, health or environment
Criteria may be weighted to arrive at final priority

19.  Baseline can be monthly or yearly
 The data in Energy Review used for baseline
 Improvement in energy performance, if any
are assessed with reference to baseline
 Adjustment to baseline may have to be done
to normalize against variation in influencers

20. Typical EnPIs
 % Energy Conversion Efficiency (Output/Input)
 KWh per SM area per year for facility building
 KWh or MBTU per Ton of production/year for plant
 KW per100CFM of Air Compressor or Fan/Blower
 KCal or BTU per Ton steam for Boiler
 KCal or BTU per Ton/Kg of material for furnace
 KWh per KL or gallons for pumps
 KWh per unit output for process motors
For comparative purpose, ENPIs need to be normalized for
factors like weather, operating hours, working conditions

21.  Objective: Reduce energy consumption in Facility-1
 (Based on prioritized list of opportunities in ER)
 Target No.1: Reduce lighting energy by--
 Target No.2: Reduce HVAC energy by --
 Target No.3: reduce Equipment energy by –
 Note: The objectives can emanate not only
from the prioritized list in ER but also from
Energy policy and Legal/other requirements
 Use of renewable energy can also be included
in the objectives and targets which have to be
specific with reference to timeframe

22. Energy Management Action Plan to include
 Objectives & Targets covered
 Project from Design to commissioning
 Responsibility for project Implementation
 Required resources
 Mode of execution & type of contratc
 Dates of commencement and completion

23. Essential Requirement
of
Continual Improvement
in EnMS and Energy performance
is demonstrated by ensuring to incorporate:-
 Proper Measurement and monitoring Systems
 Proper Documentation Management System

24. Why Go For ISO-50001 Implementation?
Because
 It targets the bottom line directly by cutting
operational costs and improving profitability.
 It helps to maintain competitiveness.
 It Demonstrates your sustainability leadership
as being environment conscious in reducing
GHG emissions and retarding climate change
as well as being natural resources conscious.

25. Because Energy saved by EM
 is the cleanest and cheapest source of energy
 leads to reduced costs increasing profitability
 requires no clearances
 requires no additional transmission lines
 attracts no public resistance and controversy.
Insight
Energy Efficiency is the low hanging fruit. Pluck it
