15. ENERGY AUDIT SKILLS
Basic qualities of Energy auditor:
Energy Auditor should be technically well versed with
manufacturing processes, energy utilization technologies, in
addition to awareness to statistical techniques of data
processing, applied economics and cost accountancy.

16. ENERGY AUDIT SKILLS
Technical skills are a pre requisite in improving the energy
efficiency of a process or equipment such as boilers, furnaces
etc. For example, to improve the boiler efficiency one
need to know the principles of combustion, heat transfer and
steam generation.

17. ENERGY AUDIT SKILLS
Managerial skills which includes bringing about awareness,
motivating people at all levels,recommending for the structure &
procedure, reviewing the energy consumption, norms target
setting, etc. Both the organizational and people changes are
required. For example, a mere awareness campaign in an
industry for switching off lights, fans and air conditioners brought
about a significant reduction in energy consumption.

18. ENERGY AUDIT STRATEGY
Energy Audit should be seen as a continuous process. Key
activities are outlined below; strategies should be reviewed
annually, and revised as necessary.
1. Identify a Strategic Corporate Approach
2. Appoint Energy Auditor
3. Set up an Energy Monitoring and Reporting System
4.Conduct Energy Audit
5. Formalize an Energy Management Policy Statement
6. Prepare and Undertake a Detailed Project
Implementation Plan
7. Implement a Staff Awareness and Training Program
8. Annual Review

19. ENERGY AUDIT - METHODOLOGY
Energy Audit is the key to a systematic approach for decisionmaking in the area of energy management.
As per the Energy Conservation Act, 2001 Energy Audit is
defined as “the verification, monitoring and analysis of use of
energy including submission of technical report containing
recommendations for improving energy efficiency with cost
benefit analysis and an action plan to reduce energy
consumption”.

20. ENERGY AUDIT - METHODOLOGY
Type of Energy Audit
The type of Energy Audit to be performed depends on.
- the function and type of industry
- the depth to which final audit is needed, and
- the potential and magnitude of cost reduction desired
Thus Energy Audit can be classified into the following two
types.
i) Preliminary Audit
ii) Detailed Audit

21. ENERGY AUDIT - METHODOLOGY
Preliminary energy audit is a relatively quick exercise to:
• Establish energy consumption in the Unit
• Identify the most likely (and the easiest areas for attention)
• Identify immediate (especially no-/ low-cost) improvements/
savings
• Set a ‘reference point’
• Identify areas for more detailed study/measurement
• Preliminary energy audit uses existing, or easily obtained,
data
• Estimate the scope for saving

22. ENERGY AUDIT - METHODOLOGY
Steps in Conducting a Preliminary Energy Audit
1. Plan how to obtain useful data
Plan how to win the involvement/Commitment of others
2. Collect data
• Collect the existing data e.g., a energy bills(volume/cost)
• Collect the Production output/records plant layouts using
checklists

23. ENERGY AUDIT - METHODOLOGY
3. Analyse data:
• Find unit cost of energy (Rs./ kWh for all types)
• Find fixed and variable energy element
• Derive ‘energy Index’: energy cost/unit output ,energy
cost/floor area

24. ENERGY AUDIT - METHODOLOGY
4. Formulate plan:
Formulate Immediate energy-saving actions: Where? How ?
How much?
• Areas to investigate further
• Resources required for more detailed study
5. Actions and monitoring
6. Next steps (e.g. detailed audits), where needed

25. ENERGY AUDIT - METHODOLOGY
Detailed energy auditing is carried out in three phases,
namely
1. Pre Audit Phase
2. Audit Phase
3. Post Audit Phase

26. ENERGY AUDIT - METHODOLOGY
Phase I –Pre Audit Phase
Step 1
• Planing and organising
• Walk through Audit
• Data collection using the checklist
• Familiarization of process/plant activities
Step 2
Conducting brief meeting awareness programme with all
divisional heads and persons concerned

27. ENERGY AUDIT - METHODOLOGY
Phase II –Audit Phase
Step 3
Primary data gathering, process flow diagram, &Energy Utility
Diagram
Preparation of process flow charts [All service utilities system
diagram (Ex.Single line power distribution diagram, water,
compressed air & steam distribution.]
Annual Energy Bill and energy consumption pattern (Refer
manual, log sheet, name plate,interview)
Design and operating data and schedule of operation

28. ENERGY AUDIT - METHODOLOGY
Step 4
Conducting survey and monitoring
Measurements :
Motor survey, Insulation, and lighting survey with portable
instruments for collection of more and accurate data. Confirm
and compare operating data with design data.
Step 5
• Conduct of detailed trials /experiments for selected
equipments
• Few hours power monitoring (MD, PF, kWh etc.) .
• Load variations trends in pumps, fan, compressors etc.

29. ENERGY AUDIT - METHODOLOGY
Step6
• Analysis of energy use: Energy and Material balance &
energy loss/waste analysis
Step 7
• Identification and development of ENCON opportunities
• Conceive, develop, refine ideas
• Review the previous ideas suggested by unit personal
• Review the previous ideas suggested by energy audit if any
• Use brainstorming and value analysis techniques
• Contact vendors for new/efficient technology

30. ENERGY AUDIT - METHODOLOGY
Step 8
Cost benefit analysis
• Assess technical feasibility, economic viability and
prioritization of ENCON options for implementation
• Select the most promising projects
• Prioritise by low, medium, long term measures
Step9
• Reporting & Presentation to the Top Management
• Documentation, Report Presentation to the top
Management.

31. ENERGY AUDIT - METHODOLOGY
Step10
Phase III –Post Audit phase
Implementation and Follow up
Assist and Implement ENCON recommendation measures
and Monitor the performance
• Action plan, Schedule for implementation
• Follow-up and periodic review

32. ENERGY AUDIT - METHODOLOGY
The instrumentation required to carry out the audit.
Electrical Measuring Instruments:
These are instruments for measuring major
electrical parameters such as kVA, kW, PF,
Hertz, kvar, Amps and Volts. In addition
some of these instruments also measure
harmonics.
These instruments are applied on-line i.e on
running motors without any need to stop the
motor.

33. ENERGY AUDIT - METHODOLOGY
Combustion analyzer:
This instrument has in-built chemical cells which measure
various gases such as CO2, CO, NOX, SOX etc
Fuel Efficiency Monitor:
This measures Oxygen and temperature of the flue gas.
Contact thermometer:
These are thermocouples which measures for example flue
gas, hot air, hot water temperatures by insertion of probe into
the stream.
Infrared Pyrometer:
This is a non-contact type measurement which when directed
at a heat source directly gives the temperature read out. Can
be useful for measuring hot jobs in furnaces, surface
temperatures etc.

34. ENERGY AUDIT - METHODOLOGY
Pitot Tube and manometer:
Air velocity in ducts can be measured using a pitot tube and
inclined manometer for further calculation of flows.
Speed Measurements:
In any audit exercise speed measurements are critical as thay
may change with frequency, belt slip and loading.
A simple tachometer is a contact type instrument which can
be used where direct access is possible.
More sophisticated and safer ones are non contact
instruments such as stroboscopes.

35. ENERGY AUDIT - METHODOLOGY
Leak Detectors:
Ultrasonic instruments are available which can be used to
detect leaks of compressed air and other gases which are
normally not possible with human abilities.
Lux meters:
Illumination levels are measured with a lux meter. It consists
of a photo cell which senses the light output, converts to
electrical impulses which are calibrated as lux.
