2Topics Evaluation objectives Categories of programs and evaluations Some more on the Action Plan GuideCalculating energy savings and avoided emissionsIssues to think about when designing evaluation efforts and issues for discussion todayResources - references
3Why Evaluate Energy Efficiency Programs? Accountability. Document and measure the effects of a program in order to determine how well it has met its intended outcomes (goals).Improvement. Understand why those effects occurred and identify ways to improve current and future programs
4Efficiency Program Categories - by their primary objectives Resource acquisition. Directly achieve energy savings, and possibly avoid emissions, through specific actions.Market transformation. Change the way in which energy efficiency markets operate and achieve either naturally occurring efficiency or incremental codes/standards. Can also include support for emerging technologies.Codes and standards. primary objective is to define and enforce mandated levels of efficiency in buildings and products.Education and training. primary objective is to inform consumers and providers about energy efficiency and encourage them to act on that information.
5Efficiency Evaluation Categories Impact evaluations. Determine the impacts (usually energy savings) and co-benefits that directly result from a program.Process evaluations. Assess how efficiently a program was or is being implemented.Market effects evaluations. Estimate a program’s influence on encouraging future energy efficiency projects because of changes in the marketplace.Cost-effectiveness analyses. Typically seen as an extension of impact evaluations, but may also take into account market evaluation results considering market penetration over the expected lifetime of the measures.
6Back to the NAPEE Guide - Why a Program Guide? Programs are different from projectsThere are widely recognized protocols for the measurement and verification (M&V) of energy savings from single projectse.g., International Performance Measurement and Verification Protocol (IPMVP atPolicy neutral guides for determining savings from programs must be interpreted from existing specific program protocols
7Guide Scope: Programs Addressed Primary focus (i.e., includes detailed guidance):Resource acquisition, downstream energy efficiency programs - directly achieve energy and/or demand savings, and possibly avoid emissions, through specific actionsSecondary focus (i.e., addressed, but no detailed guidance):Other demand-side programs: Market transformation, codes and standards, demand response, and upstream efficiency programsSupply-side programs: renewable energy and combined heat and power (CHP) program
9Guide Contents Also includes about 40 “sidebars” of examples/clarifications and 25 figures and tablesPart 1Executive SummaryPart 2Chapter 1: IntroductionChapter 2: Energy Efficiency Program EvaluationChapter 3: Impact Evaluation BasicsPart 3Chapter 4: Calculating Gross Energy and Demand SavingsChapter 5: Calculating Net Energy and Demand SavingsChapter 6: Calculating Avoided Air EmissionsPart 4Chapter 7: Planning An Impact EvaluationPart 5Appendix A: Leadership Group ListAppendix B: GlossaryAppendix C: Other Evaluation TypesAppendix D: UncertaintyAppendix E: Resources and ReferencesAppendix F: Renewables and Combined Heat and Power Program EvaluationAppendix G: References
10Guide Audience Policy-makers: Program evaluation managers: Information about the basic principles of efficiency evaluationProgram evaluation managers:Resources and background on evaluation and statistical analysesGuidance, or a roadmap, on process and key issues relating to documenting energy/demand savings and avoided emissionsProgram designers:Understanding of how their programs will be evaluatedEnergy efficiency community:Common terminology definitionsA central reference documentReferences for publicly available best practices resourcesUnderstanding of efficiency’s potential value as an emissions control strategy
11Impact Evaluation Results Reported Estimates of gross savings. Gross energy (or demand) savings are the change in energy consumption and/or demand that results directly from program-promoted actions taken by program participants regardless of the extent or nature of program influence on their actions.Estimates of net savings. Net energy savings refer to the portion of gross savings that is attributable to the program. This involves separating out the impacts that are a result of other influences, such as consumer self-motivation. Given the range of influences on consumers’ energy consumption, attributing changes to one cause (i.e., a particular program) or another can be quite complex.Estimates of co-benefits. A co-benefit commonly documented and reported is avoided air emissions: the air pollution or greenhouse gases that would have been emitted if more energy had been consumed in the absence of the energy efficiency program.
12Approaches for Determining Gross Energy Savings One or more measurement and verification (M&V) methods from the IPMVP are used to determine the savings from a sample of projects. These savings are then applied to all of the projects in the program.Deemed savings, based on historical and verified data, are applied to conventional energy efficiency measures implemented in the program.Statistical analyses of large volumes of metered energy usage data are conducted.
13Approaches for Determining Net Energy Savings The primary, but not exclusive, considerations that account for the difference between net and gross savings are free riders and participant and non-participant spillover.Approaches (categories):Self-reporting surveysEnhanced self-reporting surveysStatistical models that compare participants’ and non-participants’ energy and demand patternsStipulated net-to-gross ratios
14Approaches for Determining Avoided Emissions Applying emission factors (e.g., pounds of CO2 per MWh) to net energy savingsUsing emissions scenario analyses, e.g., using computer models to estimate the difference in emissions from power plants with and without the reduced electricity consumption associated with an efficiency program.
15Issues Addressed in NAPEE Guide Defining evaluation goals and scale and which benefits to evaluateSetting time frame for evaluation and reporting expectationsSetting spatial boundary for evaluation (i.e. what energy uses, emission sources, etc. will be included in the analyses)Defining baseline, baseline adjustments, and data collection requirementsEstablishing a budget vis-à-vis expectations for quality of reported resultsSelecting impact evaluation approaches for gross and net savings calculations and avoided emissions calculationsSelecting who (or which type of organization) will conduct the evaluation
16Evaluation Issues for Discussion Context:Efficiency is the first resource and a critical part of cheap, reliable, clean and stable energy systemsEfficiency is the first mechanism for energy sector climate change mitigation50- 80% GHG emissions reduction is required for climate stabilizationEE has a key role according to IPCC, IEA, McKinsey and other studiesEach jurisdiction's resource and climate impact evaluation requirements are not policy-neutral (but the Guide is)
17Evaluation Issues for Discussion How will efficiency savings be documented as real?What is additional?How does one attribute the savings to a particular activity?How accurate is accurate enough and how do you balance quality of results and evaluation budgetsWill cross-jurisdictional, post-Kyoto, national or international requirements (standards) be established? Is that a good idea?How will the data, tools and technology for cost-effective EM&V be developed and supported?Who should do evaluation, the program administrator, the regulator, and/or third-parties?
