Introduction to EE Measures Evaluation National Energy Efficiency Action Plan Monitoring and Evaluation Yemen, 11 December 2012
Macro Level Evaluation Top-down approach refers to theTop – Down Approach method of energy savings evaluation where “amount of energy savings or energy efficiency progress are calculated using national or aggregated sectorial levels of energy saving as the starting point.” (Bruno Lapillonne, 2009)
Macro Level Evaluation Bottom – Up Approachbottom-up evaluation starts from data atthe level of a single energy efficiencyimprovement (EEI) measures, mechanism,programme, or energy service […], andthen aggregates results from all EEImeasures […] to assess its total energysavings in a specific field.” (EvaluateEnergy Savings EU)
EE Measures EvaluationImpact …• Determine the impacts (e.g., energy and demand savings)• Define co-benefits (e.g., avoided emissions, health benefits, job creation, energy security, transmission/distribution benefits, and water savings) that directly result from a program.• Support cost-effectiveness analyses aimed at identifying relative program costs and benefits.
EE Measures EvaluationMarket• Estimate a program’s influence on encouraging future energy efficiency projects because of changes in the energy marketplace.• Assess market transformation elements and objectives.
EE Measures EvaluationProcess• Assess program delivery, from design to implementation,• Identify bottlenecks, efficiencies, what worked, what did not work, constraints, and potential improvements. Timeliness• Identifying opportunities for improvement is essential to making corrections along the way.
Measure Planning TemplateTitle of the measureObjective The purpose and motivation behind this measure. Why do you do it?Description of the What do we do? Which technologies are applied ? How is itmeasure done?Implementing agency Agency in charge of implementation and appraisal of the resulting electricity savingsStakeholders involved Other Partners involved in implementing of the EE measures in a supportive role or negatively or positively affected by the measure.Target group Group(s) which benefits from the EE measureProgram cost The total amount to implement the program, except financial contributions and investments by the target group (beneficiaries)Total resource cost Program costs plus, if applicable, contributions by beneficiariesCost / kWh saved Cost effectiveness calculation as outlined in Annex
Measure Planning TemplateReduction of subsidies State your own assessment of how and by which amount State subsidies or consumer cross subsidies for electricity supply are reduced by the measureSource of funding List all entities and parties that contribute to the total resource costsFinancial instruments List all fiscal and financial instruments such as investment grants, tax incentives, preferential interest rates, rebates, gifts contributing to the total resource costsAwareness Describe how the measure is marketed and list public awareness campaigns associated with the measuresMonitoring and Describe the algorithm how to calculate the impact and the strategyquantification of impact how to collect the data necessary to apply the algorithm
Program Implementation Cycle With Evaluation Activities
SMART TargetClearly identified energy efficiency objectives withspecified timelines constitute one of the attributes ofsuccessful energy efficiency strategy. Energy efficiencytargets are useful in motivating implementing agencies tobe more pro-active and measuring the progress of energyefficiency initiatives.Targets can be expressed in different ways as long asthey remain SMART: specific, measurable, ambitious,realistic and time-bound
Two Components to M&V• Verify potential to generate savings• Determine savings Example: Lighting Retrofit - Potential to Generate Savings: Before 100 Watts/fixture After 23 Watts/fixture Savings: Savings determined using a variety of approaches how many fixtures and operating hours
Evaluation AppraochesCFL Program Number of CFL Distributed Installed Replaced
CFL Replacement The formula provides for the evaluation of annual energy savings derived from the replacement of lamps with new more energy efficient ones or installation of new lamps. The annual unitary final energy savings (in kWh/unit/year) for lamp replacement are calculated by the difference between the lamp stock average power consumption in the reference year ("before" situation) and the power of the efficient lamps sold or installed. In case of additional lamps the market average power consumption in the reference year should be used for the "before" situation. The total annual energy savings achieved [kWh/year] are calculated by multiplying annual unitary final energy savings by the number of efficient light bulbs sold or installed for residential use.

Solar water heating in residential and tertiary buildings• The formula provides for the evaluation of annual energy savings derived from the installation of solar panels for water heating in existing or new residential and tertiary buildings.• The annual unitary final energy savings for new solar water heating systems are calculated on the basis of the average annual energy savings per m2 of solar panel, divided by the average efficiency of the replaced water heating systems stock in the reference year of installation [in kWh/m2/year].• The reference year is the year when the solar water heating unit was installed.• The total annual energy savings achieved [kWh/year] are calculated by multiplying the annual unitary final energy savings by the total installed area in m2 of solar panels after 1995 (1991).
Solar water heating in residential and tertiary buildingsUSAVE = Average annual savings per m2 of solar panel, representing theaverage heat production per m2 of solar panel [kWh/m2]ŋstock _ average_ heating = Efficiency of the average stock water heaters orheating systems in the year when the solar heater was installed.Note: This is the efficiency of the existing installed stock and not the efficiencyof the solar heaters.
