ESTCP's Principal Investigator (PI) Chuck Hammock, PE of Andrews, Hammock & Powell Consulting Engineers and Eric Myers, PE (Gulf Power) will also discuss the Utility Company perspectives on UTES as a potential Energy Conservation Measure (ECM) under a UESC contract. This webinar will provide an overview of implementing a UTES Project with some or all of the capital costs being borne by a UESC or another Contracting Vehicle. We will also provide a system overview of this unique HVAC architecture and explore techniques for funding the system, or system components, via the UESC contracting vehicle.
