The Goal
Energy Cost Reduction
through

Energy efficiency

Alternatives

Reliable services

Productivity
How to Reach the Goal
1. Request
2. Energy Audit
3. Business Plan
4. Due Diligence
5. Design
6. Procurement
7. Implementation
8. Commissioning
9. Follow-up
1.
Request

Tell us you are interested.

Discuss your goals.

Walkthrough

Define what is possible.

Agree on a course of action.

Proposal
- Scope of work & price proposal

1st Contract
- 2 signatures
- 1st client meeting & quick inspection
2. Energy Audit
Definition: a feasibility study to find and recommend
energy & cost reduction opportunities
Procedure:
1. 3 site visits
- Investigation, identification of savings
opportunities from interviews, records,
measurement and data logging
2. Research
- Market search for feasible technical solutions
3. Analysis
- Definition of measures, determination of
feasibility
4. Report
- Comprehensive set of recommendations
5. Presentation
- Personal explanation of audit report to client
Energy Audit (cont.)
Result: a report explaining recommended opportunities
measure by measure
Indicators:
• IRR
• NPV
• Energy savings
• Cost savings
• Investment
• Emissions reductions
Objectivity:
• Auditor is independent of other vendors; sells no product.
• Auditor represents best interests of client.
3. Business Plan

Only necessary for large projects

Gives investors security

Either whole business or project specific

Defines type of contract between client and GESI
4. Due Diligence

Financial credibility

Insurance, permitting and licensing issues addressed

Binding legal agreement

Agreement by all to move forward
5. Design

Begins with audit analysis

Measurement & calculation

Equipment specification

Less effort with Level 3 audit, more with Level 2 audit
6. Procurement

Depends on type of contract

Procedure determines timeframe.

GESI’s responsibility in performance contract

Client’s responsibility in other contract types

Full competitive, partial competitive or sole source

GESI assists as requested.
7. Implementation

GESI builds project according to design

Schedule set by suppliers’ delivery and scope of labor

Performance contract: Full responsibility on GESI

Non-performance contract: Progress payments in clearly
defined stages
8. Commissioning

Start-up

Testing

Performance verification

Correction of defects

Acceptance by client
9. Follow-up

Measurement & verification (M&V) – verifies savings

Preventive maintenance (PM) – preserves savings

Follow-up depends on type of contract.

Hard requirement for performance guarantees (risk on GESI)

Optional for other arrangements (risk on client), as requested
by client
Case Study 1.
US ENVIRONMENTAL PROTECTION AGENCY (EPA)
NATIONAL VEHICLE AND FUEL EMISSIONS LABORATORY
1. Installed two York Millennium two stage absorption
chiller/heaters rated at 440 tons and 575 tons of cooling,
respectively, a new cooling tower, and one 3200 MBtu/h Bryon hot
water generator.
2. Installed 34 air handling units (AHUs), customized according to
planned operation.
3. Installed a 1200-point energy management system.
4. Replaced old motors with high-efficiency equivalents.
5. Converted once-through cooling water systems to closed loop
cooling.
6. Installed power factor correction.
7. Installed a 200-kW ONSI fuel cell.
Reductions
(EPA Case Study cont.)

Annual energy cost by 60%

Annual water consumption by 60%
Goals (EPA Case Study cont.)
1. Meet or exceed Federal energy reduction mandates
2. Reduce power plant source emissions
3. Optimize energy cost savings.
4. Restore obsolete and aging infrastructure.
5. Eliminate or replace chlorofluorocarbons (CFCs)
6. Minimize energy waste
7. Maximize the use of the waste energy streams, to feed other
processes
8. Use renewable energy (photovoltaic, solar thermal, passive
solar, biomass, wind, geothermal, hydropower, and other
alternative technologies, such as cogeneration, where cost
effective).
Costs & Savings (EPA cont.)

$11 million investment by ESCO

22 years of complete system operation and performance
guarantees

Annual contract payments of $1 million

Includes $200,000 of annual operation & maintenance
Case Study 2.
Dallas/Fort Worth International Airport (DFW)
Rusty T. Hodapp, P.E., CEM, CEP, LEED,
Energy & Transportation Management Vice President,
Dallas/Fort Worth International Airport
DFW Airport Overview

Jointly owned by Cities of Dallas and Fort Worth

Opened in 1974

The world’s 2nd largest airport encompassing 18,000 acres
including 9,000 acres of natural resource areas

Ranked third worldwide in operations totaling over 804,000
annually

Ranked sixth worldwide in serving 60 M passengers
Energy Efficiency Program
(DFW cont)

Initiated in 1975

Based on 3 Primary Elements
1. Sound operation and maintenance practices
2. Retrofits where economically and technically feasible
3. Incorporation of energy efficiency into new construction

Dedicated Energy Engineer/Manager since 1979 (Energy
Engineer and Analyst added in 2003)

Energy consumption avoided to date is estimated at over 25
trillion BTU (~5 million barrels of oil)

Conclusion

Today: Energy security a serious concern for countries
dependent on single fuel sources.

Efficiency reduces dependency.

Redundancy reduces risk.

Average 20% global energy price rise

Will continue, not recede

Competitive edge

Never wait to decrease costs and increase reliability.
