Slide 3 If you cant measure it, you cant manage it . Measurement and Verification: quantifying actual savings created within an individual facility Slide 4 Measurement vs. Verification Measurement is used to develop baseline data on energy use and helps to identify potential energy projects. Measurement monitors and assigns avoided energy costs (savings) to buildings/facilities, departments, projects and equipment. Measurement is used to evaluate the performance of project to assure project operation and implementation is adequate Verification is used to evaluate performance of project to assure that projected, and if applicable, promised, impact occurred: Project performance is the project living up to its potential? Promised performance is the project living up to its (financial) promise?

It does not have to be fancy Slide 6 What does it look like?

(Example from UNC-Chapel Hill M&V Program) Slide 9 How do you currently track your colleges energy use? Slide 10 Some Benefits of M&V Improve general operations and maintenance Monitor equipment performance Ensure proper implementation of energy projects Increase awareness of sustainable energy initiatives on campus Slide 11 Some Benefits of M&V (cont.) Verify that the projected avoided energy use/savings occurs Reduce cost of financing Find areas for additional energy reductions and savings Maximize energy savings by allowing for future adjustments as needed Slide 12 If someone asked you personally which building used the most total electricity? You would Slide 13 If someone asked you personally which building used the most total energy per square foot? You would Slide 14 Lifecycle of an energy project I DENTIFY A NALYZE I MPLEMENT V ERIFY M EASURE Slide 15 Example Ferrum College Slide 16 Example Lynchburg College In 2010, Lynchburg College entered into an Energy Savings Contract with Ameresco. 22 projects were implemented: 4,557,600 kilowatt hour reduction in electricity 13,421,364 gallon reduction in water usage Ameresco provides an annual report on the energy savings, however the college has also contracted with an independent third party to measure, track and verify the savings. Slide 17 Lynchburg College Results Slide 18 Slide 19 Developing an M&V plan as part of project implementation Outline project and intended results Document baseline energy usage Determine expected avoided energy use (savings) Take changes in energy cost, weather and building use into consideration Review contracts and agreements Guarantees from energy savings performance contracts Energy use projections from contractors Define performance measurement How often will measurement occur? What types of tools will be used? How to adjust for weather and behavioral changes Slide 20 Measurement and verification components and resources Utility bills Meters and associated metering technology Building information (characteristics, usage, weather) Spreadsheets Computer models Software applications A qualified engaged analyst (internal or external) Visualization dashboards Students.. Slide 21 What best describes your situation? Our school has a Slide 22 Who is responsible? Consider the frequency of verification In-house verification Facilities Sustainability Director Energy Manager Third party verification Slide 23 How much should it cost? Consider the confidence level of the estimated energy or cost savings. Balance the savings uncertainty against the cost to execute the plan. 1% to 10% of typical project cost savings. Unproven technologies may warrant additional attention. Slide 24 Some challenges Historical utility data not available Difficulty in measurement of individual projects Comprehensive campus-wide monitoring Sub-metered building monitoring Project-specific Lack of dedicated utility meters Risk vs. benefit analysis Other influences (weather, behavioral) Slide 25 Resources Lawrence Berkeley National Laboratory Measurement and Verification Portal http://mnv.lbl.gov/ http://mnv.lbl.gov/ M&V Guidelines: Measurement and Verication for Federal Energy Projects http://www1.eere.energy.gov/femp/pdfs/mv_g uidelines.pdf http://www1.eere.energy.gov/femp/pdfs/mv_g uidelines.pdf Energy Stars Portfolio Manager http://www.energystar.gov/index.cfm?c=evalu ate_performance.bus_portfoliomanager http://www.energystar.gov/index.cfm?c=evalu ate_performance.bus_portfoliomanager Green Revolving Investment Tracking System (GRITS) http://greenbillion.org/gritshttp://greenbillion.org/grits Slide 26 Last thought: shiny toys should be tied to objectives Slide 27 http://efc.sog.unc.edu Thank you! 27 Slide 28 http://efc.sog.unc.edu Environmental Finance Center at the University of North Carolina School of Government, Knapp-Sanders Building CB #3330 Chapel Hill, NC 27599-3330 USA Jeff HughesJennifer Weiss jhughes@sog.unc.edujweiss@sog.unc.edu 919-843-4956504-606-8148 jhughes@sog.unc.edujweiss@sog.unc.edu
