1 Measuring and Verifying Your College's Energy Savings Jeff Hughes, Director Jen Weiss, Senior Finance Analyst Environmental Finance Center at the University of North Carolina Jessie Ball duPont Fund Measurement and Verification Webinar October 10, 2013

2 Does your school use sub-metering?

3 “If you can’t measure it, you can’t manage it ….” Measurement and Verification: quantifying actual savings created within an individual facility

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?

9 How do you currently track your college’s energy use?

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

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

15 Example – Ferrum College

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.

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

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…..

21 What best describes your situation? Our school has a…

22 Who is responsible? Consider the frequency of verification In-house verification Facilities Sustainability Director Energy Manager Third party verification

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.

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)
