introduction to energy audit part 3
DESCRIPTION
This is a compilation of the overall process in conducting energy audit based on my personal experiences, training that I attended in Malaysia, India and Japan and information sharing between fellow EE practitioners.Not to forget references from books and internet. I believe this would benefit to those who wants to understand what is energy audit all about for beginners to become energy auditor and to facilities owners to assess the need to conduct energy audit and energy audit proposals submitted by consultantsTRANSCRIPT

ENERGY AUDIT :
APPROACH & METHODOLOGY (PART 3)
1
ENERGY EFFICIENCY INFORMATION
SHARING SERIES
PART 3:
Energy Audit Report &
Presentation
2
Prepare Energy Audit Report
After successfully carried out energy audit
energy manager/energy auditor should report to
the top management for effective
communication and implementation
The report format should be tailored to make it
more attractive to the management
3
Energy Audit Report …(1)
Executive
Summary
Objectives, scope, type or audit and
summary of energy saving recommendations
Management
Of Energy
Policy and targets
Energy data, documentation and
monitoring
Compliance towards the regulations
Energy management team
Energy audit team
Plant/Building
Production/se
rvices
Description
Brief description for production process-
manufacturing/services-buildings
Process flow diagram and major
components of operation

Energy Audit Report…(2)
Energy
Supply
Information
Total electricity supplied and trends
Sources and types of energy supply
Costs of energy supply (price, tariff).
Utility
system
description
Brief description of each utility
system and major equipment
Current energy performance/energy
efficiency status (energy intensity) for
plant, processes and major energy using
equipment 5
6
Energy Audit Report…(3)
Energy
Consumption
Information
Load profile data and charts
Estimated annual energy consumption in
energy unit (electricity/fuel) and the
percentage (%) of load distribution such HVAC,
production machinery, lighting and etc;
Operating hours of the installation and major
energy using system/equipment
Energy Supply
And
Consumption
Analysis
Conclusions from supply and consumption
profiles and trends from energy bills and
measurements
Suitability of energy supply types and
tariff/prices
Current energy performance status (energy
intensity) for plant, processes and major energy
using equipment
Energy Audit Report…(4)
Energy Saving
Measures
Summary of energy saving potentials and measures
identified:
•No cost/low cost : housekeeping, minor repairs
•High cost/major investment required: major
repair/replacement / introduction of new technologies
Potential of energy savings in energy unit and
currency;
Energy saving measurements and calculations
methods;
Potential returns from the costs to implement
energy saving measures ( Simple Payback Period/
IRR)
Financing options/Government Incentives available
Proposed action plan and estimated time required
to implement each measure
Energy Saving
Measurement &
Verification
Baselines to be used to measure results
Measurements & verification methods

What is the next steps?
• To convince the decision makers and
key players in the organization
• Mostly decision makers are with no or
little technical background and
generally more concern on core
businesses and financial returns!

Present findings to the top
management for approval to
implement….
11
Present Findings
To convince the top management to implement energy saving measures – require investments
To present key data that the management team members are keen to see for making decisions
12
Tips to convince the top management
1. Convince other key players -supports from other key departments/division(finance, production & etc)
2. Prepare effective presentation materials or write ups Strong business case in key points Specifically structured and prepared All possible key points to attract their attention must be carefully studied and
identified To be tailored in the proposal- all possible doubts, concerns or points to argue
have been addressed
3. The presentation
The presenter must be able to present it confidently and convincingly To highlight key points
• economic benefits • contribution to profitability • improvement of energy performance • faster and high returns for investments • high success factors • technical feasibility -proven technologies and case studies 13
Example of Successful ESMs Implementation:
Private Commercial Shopping Complex …(1)
Areas of Implementation: Transformers Cooling System – Chillers, Cooling Towers, AHUs, CHW & CDW Pumps Lighting System – Internal, External & Parking Demand Controls
Total Actual Saving Achieved = RM 1,495,000/year
14
Example of Successful ESMs Implementation:
Private Industrial Warehouse …(2)
Application Areas:
- Fluorescent Lamps
- High bay Lighting - HID
Total Annual Actual Saving Achieved = 42.2% = 3,283,200 kWh, = RM 920,000 15
Example of Successful ESMs Implementation : Pilot Project for
Public Lighting -Comparison Before & After Implementation
(Before) Conventional HID 250W (After) LED 150W
