5. UNC-Chapel Hill Campus Energy (Electric, Steam, Chilled Water) Electricity From Duke Power Duke Power Electric Substations Electricity to Campus Electricity Generated by Cogen Campus Electricity to Chiller Plants For Electric Chillers, Pumps, etc. Campus Buildings Use Steam, Chilled Water and Electric Power Distributed Across Campus Chilled Water Supply to Campus Chiller Plants (on Campus) Chilled Water Return from Campus Electricity to Cogen Steam Condensate back to Cogen Steam to Chiller Plants For Steam Absorption Chillers They return steam Condensate to the Cogen Facility to be used again to produce Steam. Coal Cogeneration Facility (Steam & Electric) Nat’l Gas Steam to Campus Fuel Oil Steam Condensate from Campus

7. Energy Management:Ralph Taylor – Energy Manager • Strategic Energy Plan • Provide Energy Management and Consulting Services • Mechanical Systems /Optimization • EE Motors, VAV, VFD, Enthalpy, Economizers • Develop Operating Control Strategies. • Electrical Systems /Optimization • Lighting, T8, Halogen, HPS, MH, Power Factor Improvement • Identify Energy Conservation Measures • Prepare Proposals with Recommendations • Prepare Life Cycle Cost Analysis • Using Internal Rate of Return Method ( IRR ) • Determine Return on Investment ( ROI )and Years Payback ( PB ) • Conservation Awareness for Campus

9. Energy Management and Control System (EMCS): Jay Evans – EMCS Operations Manager • 4 EMCS Operators + 1 Lead Operator • 7 Day Operation (Extended Hours Coverage) • Monday thru Friday: 6 AM until 10:30 PM • Saturday and Sunday: 6 AM until 4:30 PM

10. EMCS Now • Monitor Environmental Conditions in Campus Buildings and Support HVAC Operations • Control HVAC Systems and Perform Emergency Load Shedding • Respond to Operational Alarms and Operate HVAC equipment • Generate Reports for Technicians/Mechanics/Engineers • Monitor/Control Building Temperature and/or Humidity • Develop and Maintain Databases for over 30,000 Points on a Dynamic BAS using multiple vendors systems

11. The EMCS Upgrade • LONWORKS standardized for control inside of the buildings • A Library of standardized control sequences with point lists and logic diagrams for inclusion in the UNC Design Guidelines • Gateways for all Legacy and LON control systems to a common communication protocol utilizing Web Services over the Campus Ethernet • A comprehensive suite of software applications and services to provide a unified “Front End” operating environment • An IT standards-based data protocol to enable Enterprise integration for “future proof” expansion and application development • A new EBMS Operations Center including an Emergency Management Operations/Communications Center

12. Then the EMCS becomes an EBMS Other services that near future upgrades will support as we become an Enterprise Building Management System • Mechanical Systems /Optimization • Develop enhanced Operating/Control Strategies • Implement Demand Management Strategies • Support Commissioning and Retro Commissioning • Model Building Operation and implement (near) real-time Energy Modeling after occupancy • Support Sustainability and Green initiatives • Gather Data to Support Life Cycle Cost Analysis and Capital Renewal programs

13. EMCS / EBMS: • INTEGRATION • Provides a means to integrate pertinent information and make it available to those who need it to support timely business decisions • Meter information • Energy Consumption and Weather trends • Historical Data • Operational trends and deviation reports • Supply/Demand Optimization • Load Profiles and Functional Modeling • Provide Business Decision Support to Managers & Campus Customers

15. “At UNC, EBMS will allow the traditional Building Automation System (BAS) to move from a proprietary and private world, little understood by the building occupants, to a system which everyone can actively use to enhance their use of the space they occupy.”
