Why Use A DES ESCO ?

• High Energy Bills
• Old Equipment is Broken
• Bond Levy Passed
• Free Grant Money / Utility Incentive Money
• Going “Green” – Reducing Carbon Footprint
• Desire to use specific equipment or contractor

for installing large projects (avoid low bid issues that often arise)

Benefits of A DES ESCO?

• DES Screening and Oversight of ESCOs
• Guaranteed Energy Savings
• Guaranteed Maximum Costs
• Guaranteed Building Comfort
• Contracting/Subcontractor Management

ESPC Behind the Scenes

1) Starts with a phone call 2) Proceeds to an Energy Study

• We look at all building systems
• Address “issues” in the building
• Occupant complaints
• Energy modeling
• Review all incentive and grant opportunities
• Open dialogue and feedback between the owner

and the ESCO to finalize scope of work

ESPC Behind the Scenes (cont’d)

3) DES Contracts are issued (IAA / ESPC) 4) Construction begins

• Engineering/Design
• RFP’s
• Subcontractor Selection
• Construction ‐ Progress Meetings
• Substantial Completion
• Closeout – Training – O&M Manuals/Documentation

Project #1: Clallam Transit Center

• Original air conditioner was failing
• Owner had difficulty getting good service from

local contractors

• The utility company hired us for a free energy

audit

• We replaced the old 30‐ton air conditioner

with a heat pump (heater & air conditioner)

• We fixed the controls, including problems with

the controls the city did not know they had

Project #3: King County Aquatic Center

• Project was driven from comfort issues and
• ld equipment
• King County hired a Professional Engineer to

find a solution

• ESCO proposed alternate solution that saved

energy compared to the Professional Engineer’s original solution

• Actual construction costs exceeded ESCO’s

guaranteed costs, so ESCO paid the overage
