O&M Roadie or Rockstar?

1 Session: O&M Strategies: A Rock to Rockstar O&M Roadie or Rockstar? Greg Palko Ameresco August 10, 2016 Rhode Island Convention Center Providence, Rhode Island

2 What s the context?

3 Roles and Activities 3

4 How hard could it be?

5 Control and monitoring technologies will sustain the savings LBNL 100% 70% Energy Consumption Efficient devices and installation Optimized usage via automation Up to 8% per year is lost without monitoring and maintenance program Up to 12% per year is lost without regulation and control systems Monitoring & Maintenance Time 5

6 Strategic Approach to the Problem Develop alternate ROI s, i.e., energy savings PLUS other things: Safety Productivity (energy/o&m) Address aging infrastructure Develop and implement the program: Program Management Audits Energy Conservation Measures

7 The Biggest Challenge is NOT MONEY! There is PLENTY OF MONEY (It s just not available to you ) Artificial, but real separation on Utility Spending and O&M budgets

8 Lab Programs How Does the Money Flow? Utilities Budget Space Budget ($ M) 1 ($ M) 2 F&O Director F & O FMD Director 1 Divisions pay utilities in organizational burden 2 Space Budget to organizational burden 3 Space Budget divided by complex ($M) 1 Utilities Budget Utilities Manager ($M) ½ of Space Budget 3 Space Budget Complex Facilities Manager C Electricity / Natural Gas Required Maintenance * Custodial Costs Electricity / Natural Gas Staff Costs Required Maintenance * F i x e d Discretionary A B Discretionary How we spend A & B drives spending on C

9 Don t reinvent the wheel! Excellent help is available from the industry Some firms specialize in just auditing Some manufacturers and distributors can provide recommendations and design along with their products.

10 What Data do you already have? 10

11 Sensing & Measurement Support Wireless Sensing Kit Easy to install Wireless Sensor for shortterm/long term continuous audit Temperature/humidity, occupancy current, ON/OFF, hot and chilled water, steam and gas, 3 phase electric, 4 20mA, etc. Metering Integration Vendor agnostic, supporting a wide variety of meters and vendors Pulse meters, CT Meters, Flowmeters over multiple protocols and network connections: MODBUS, BACnet, Ethernet/WiFi/Broadband Page 11

12 Portfolio Level Overview of Commodity Consumption 12

13 Reports not just for the top shelf anymore Features: Consumption information at central meter level Benchmarking and Analytics Measurement & Verification Report generation Optional analyst support Benefits: Visibility datain a single repository Accountability across organization Starts identifying opportunities User empowerment 13

14 Identifying Common Issues Simultaneous heating and cooling Equipment running during an unoccupied period unnecessarily Miscalibrated or faulty sensors (e.g., broken CO 2 or outside air sensors that prevent efficient economizer operation; miscalibrated temperature sensors, etc.) Chiller operating when outside air temperature is low AHU return fan running when supply fan is off Equipment (e.g. boilers) cycles excessively VFDs operating at a fixed speed Economizer does not functioning optimally, or excessive outside air causes increased heating and/or mechanical cooling Insufficient outside air, compromising indoor air quality Page 14

15 Simultaneous Heating & Cooling MA Temp CHW Valve HW Valve This is a common low cost/no cost energy saving solution identified. l 2016 Ameresco, Inc. All rights Page reserved. 15

16 Typical Software Tiers Tier 1: Monitoring & Reporting Tier 2: Optimization & Fault Detection Optional: Public Facing Dashboards Portfolio level opportunity identification through benchmarking and analytics Measurement & Verification Building level continuous detailed analysis across 1,000s of EMS points to identify faults, supervise equipment sequencing, set points and schedules Building performance tracking, leaderboard, educational materials and sustainability Page 16

17 Typical Heirarchy 17

18 Where to get Technical Help? The staff already has a full time job Vendors/Suppliers Industrial Assistance Center FEMP GSA EPA
