2 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) 2 Benefits of A DES ESCO? DES Screening and Oversight of ESCOs Guaranteed Energy Savings Guaranteed Maximum Costs Guaranteed Building Comfort Contracting/Subcontractor Management RFP and Procurement Construction Management Commissioning Open Book Accounting 3 1

3 Who are the DES Approved ESCOs? Abacus (Willdan Energy Solutions) Ameresco Apollo Solutions Group Integrity Johnson Controls MacDonald Miller Facility Solutions McKinstry Schneider Electric Siemens Industry Sunset Air Trane University Mechanical Contractors 4 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 5 2

4 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 Measure Energy Savings 6 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 7 3
