Why Use A DES ESCO ? High Energy Bills Old Equipment is Broken - PowerPoint PPT Presentation

5/2/2016 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

5/2/2016 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

5/2/2016 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
