1 UTILITY METERING AT PURDUE ENTERPRISE ENERGY MANAGEMENT SYSTEM Jason Kutch, P.E. Malcolm Drane, P.E. AGENDA Organizational roles Comprehensive Energy Master Plan (CEMP) goals Metering program Enterprise Energy Management (EEM) System Benchmarking buildings Project identification 2 Jason Kutch, Purdue University 1

2 ORGANIZATIONAL ROLES THE TEAM BLDG CONTROLS ADACENT PROJECTS ARC FLASH BLDG OCCUPANTS ENGINEERING HIGH VOLTAGE LOW VOLTAGE UTILITIES DISTRIBUTION PM & C BLDG DEPUTIES Maintenance 3 ORGANIZATIONAL ROLES Maintain meters Add points and validation Maintain users View Screen creation Set up alarms for points Create/maintain predictive analytics models Manage Web Configuration History maintenance 4 Jason Kutch, Purdue University 2

3 CEMP GOALS Plan was developed in 2012 Analyze production, distribution, and demand Included metering all campus buildings Controls optimization of building automation systems (BAS) System wide review of chilled water i.e. chiller operation, building pumps 5 CEMP GOALS Effective Energy Management Energy Savings Opportunities Fiscally sustainable plan system wide Education and Collaboration Energy-Conscious and Environmentally responsible culture 10 year recurring energy and cost savings 6 Jason Kutch, Purdue University 3

4 Purdue Produced utilities Chilled Water Electricity Domestic Water Steam Condensate Easily identify issues Broken valve Control deficiencies Low delta T, high flows Simultaneous heating and cooling $2.3M, 43 Buildings Master plan developed $2M Approx. 40 buildings $2M Approx. 40 buildings $1M Over 140 buildings by 2015 Jason Kutch, Purdue University 4

5 ARCHITECTURE Supply & Return Temperature Domestic Water Main Chilled Water Domestic Water irrigation Power DCCP Ethernet Steam Condensate Lighting Temperature 9 METER SELECTION CRITERIA High accuracy Low maintenance Low pressure drop Smart meter verification 10 Jason Kutch, Purdue University 5

6 MECHANICAL METERS Chilled and Domestic Water meters Inline electromagnetic +/- 0.5 % accuracy No moving parts or obstructions No mechanical maintenance Steam Condensate meters Vortex Shedding +/- 1 % accuracy No moving parts No mechanical maintenance Highly accurate RTD s Chilled Water Steam Condensate 11 INSTALLATION GUIDELINES 12 Jason Kutch, Purdue University 6
