Management Systems in Industry at IISWBM, Kolkata, 9-10Mar2012
Audit of a management system is the process of evaluating the current system and comparing with the expected system requirements as laid down in the relevant standard viz.ISO-50001.
Auditor(or audit-team) who carries out the audit needs to have expertise in following domains:-
Energy Management Systems Auditing
Insight: Any ISO auditor cannot lead EnMS audit
PrologueThe Basics
Main requirements for EnMS include policy statement, Energy Leader, Energy Review, Energy Performance tracking/monitoring ,training and documentation.
In case of ISO-50001(EnMS), auditing is not limited to the management system but also includes assessment of Energy Performance through Key Indicators (EnPIs).
ISO-50001does not lay down minimum performance but stresses on management of continual improvement both in EnMS & Energy Performance Indicators(EnPIs).
This requires energy monitoring & targeting system. Two ISO-50001 certified organizations can widely differ in
energy efficiency performances. Insight
• All EnMS certified entities are not equally efficient.
Prologue contdComparing EnMS with other ISO Standards
Commitment of Top Management to get certification of ISO-50001(EnMS) is must for successful conclusion. It is better to begin with an internal audit to have a feel of the process
Don’t expect Energy Engineer to be Marketing Engineer. ISO certification calls for extensive documentation. Don’t expect Energy Engineer to be a record keeper. A seasoned Energy Auditor can sense energy
performance of the facility/plant in a glance. Let his intuitive capabilities be used for overall direction.
Frittering away Energy Engineer’s Energy is counterproductive

Components of Managerial Planning
Who decides? Top Management/MD/ED/VP Plant Manger Engineering Manger Maintenance manager Purchase Manager
What is the driving factor behind decision? Savings Environment RecognitionEconomic and environment sustainability with support from top management are essential for success of EnMS.
Ownership of EnMS Program
The company commits to Reduce energy use per unit by --% in ----years Continue the improvement in energy performance Uphold legal/other requirements regarding energy Deploy resources to achieve objectives and
targets Implement energy performance improvements Procure and utilize energy-efficient products and
services with cost effectiveness considerations Prepare an Energy manual for systematic
implementation of EnMS (Optional)
Energy PolicyMake continual improvement the thrust
Approved Energy Manual can reduce decision making process and help to achieve continual improvement in energy performance & EnMS. The Energy Manual may cover:- Scope & Boundaries of Energy Management Core Elements like Planning, implementation etc. Powers & Responsibilities of Energy Leader/Team Key Documents in EnMS
Note: Preparation of E/Manual is not prescribed in ISO-50001 but is very effective for success.
Energy Manual for Continual Energy Management
Who steers the program? Energy Champion or Energy Leader from the
organization has to be of fairly senior level. If everybody is responsible, nobody is. Members of Energy Team have to be from all
influencers like following• Production • Maintenance • Purchaser EnMS Audit can not succeed w/o Energy Team. It is also a requirement as per ISO-50001.
Constitution of Energy Team The First Step to a successful Program
To be acted upon in conjunction with Tech Plan
Objects Targets Resources Plan to implement Action PlanNote: The division of planning responsibilities into managerial and technical is for functional effectiveness and not airtight segregation.
Other Elements of Managerial Plan
Data Management: The Mainstay of Energy Review Overview of the activities affecting energy performance Recording Legal and other requirements including
availability of energy tracking/monitoring systems Collecting Energy Data including historical data and
rated power of individual equipment/system Listing Significant Energy Uses(SEUs) Establishing Energy Baseline
The energy review is based on the data obtained from various sources without use of any instruments except during energy balancing process when portable power meters are used to determine power input of individual equipment/systems.
Energy Review/ProfileFirst Part of Tech Planning
Defining Energy Performance Indicators (EnPIs)
Determining EnPIs for individual system/process by measuring output and input power
Determining EnPI of the plant from measured data
Listing Performance Improvement Opportunities
Prioritizing improvement opportunities Suggesting Energy Management Action
plans As extensive measurements are required, sampling techniques are resorted to. Detailed measurement plans have to be made and documented.
Energy Performance AssessmentSecond Part of Tech Planning
Overview Type of Business operations Activities significantly affecting energy use Existence of monitoring & control systems
Legal and Other requirements Essential requirements for business ops Statutory requirements Other requirements
Energy Review contd
Overview,Legal and Other Requirements
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
Energy Review contd
Typical Data
Who, from Energy Team, will list out the data to be collected define the form & format of data collect the data, when & wherefrom check the accuracy of data collected receive and store the data for later analysis check functioning of above process check if anything missing
Energy Review contdDefining Responsibilities for data collection
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 SEUsNote:-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
Listing Significant Energy Uses(SEUs)
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 motorsFor comparative purpose, ENPIs need to be normalized for factors like weather, operating hours, working conditions

Anything missing in planning?
IPEEC’s Programs International partnership for Energy efficiency Cooperation
(IPEEC) has launched Global Superior Energy Performance (GSEP) on the pattern of USA’s SEP Program.
Objectives are as under:- Increase the implementation of EM in industries and buildings in order to
improve energy efficiency and energy performance. Measure and verify energy performance improvements. Build a qualified workforce of professionals with expertise in the fields
of energy management, energy efficiency, measurement & Verification (M&V).
Three Taskforces established as under:-o EM Task-Force: For certification processes on the pattern of ISO-50001o M & V Task-Force: For standardizing M&V Protocolso Qualified Work-Force Task-force: For credentialing EE/EM
professionals
Moving Beyond ISO-50001
All Enterprises Realize that EM means improved bottom line Begin with an internal EnMS audit Select EM consultant after proper evaluation Measuring and accessing energy info in near real
time leads to devising EM measures.
Micro, Small and Medium Enterprises (MSMEs) Min of MSME reimburses expenses for certification
related to ISO-9001 QMSs. Industry Associations may take up with M/O MSME
for similar concessions for ISO-50001 certification. It can lead to an energy management revolution.
Advice to Prospective Clients
Do not go near a facility that doesn’t welcome you
Keep sharpening your analytical tools Do not restrict your activities to energy audits.
Get into the domain of Energy Management Services
Association of Energy Engineers(AEE) is the best professional forum for energy engineers
