This document discusses approaches to evaluating energy efficiency measures at both the macro and micro levels. It describes top-down and bottom-up approaches to macro-level evaluation, where top-down evaluates energy savings at an aggregated level and bottom-up evaluates individual measures and aggregates the results. For micro-level evaluation, the document outlines how to determine the impacts, market effects, and process of energy efficiency programs and measures. It provides templates for planning and evaluating specific measures, calculating energy savings, and implementing an evaluation program cycle.

1. Introduction to EE Measures Evaluation
National Energy Efficiency Action Plan
Monitoring and Evaluation
Yemen, 11 December 2012

2. Macro Level Evaluation
Top-down approach refers to the
Top – 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)

3. Macro Level Evaluation
Bottom – Up Approach
bottom-up evaluation starts from data at
the level of a single energy efficiency
improvement (EEI) measures, mechanism,
programme, or energy service […], and
then aggregates results from all EEI
measures […] to assess its total energy
savings in a specific field.” (Evaluate
Energy Savings EU)

4. EE Measures Evaluation
Impact …
• 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.

5. EE Measures Evaluation
Market
• Estimate a program’s influence on encouraging future
energy efficiency projects because of changes in the
energy marketplace.
• Assess market transformation elements and
objectives.

6. EE Measures Evaluation
Process
• 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.

7. Measure Planning Template
Title of the measure
Objective 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 it
measure done?
Implementing agency Agency in charge of implementation and appraisal of the
resulting electricity savings
Stakeholders 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 measure
Program 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 beneficiaries
Cost / kWh saved Cost effectiveness calculation as outlined in Annex

8. Measure Planning Template
Reduction 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 measure
Source of funding List all entities and parties that contribute to the total resource
costs
Financial instruments List all fiscal and financial instruments such as investment
grants, tax incentives, preferential interest rates, rebates, gifts
contributing to the total resource costs
Awareness Describe how the measure is marketed and list public
awareness campaigns associated with the measures
Monitoring and Describe the algorithm how to calculate the impact and the strategy
quantification of impact how to collect the data necessary to apply the algorithm

9. Program Implementation Cycle With Evaluation Activities

10. SMART Target
Clearly identified energy efficiency objectives with
specified timelines constitute one of the attributes of
successful energy efficiency strategy. Energy efficiency
targets are useful in motivating implementing agencies to
be more pro-active and measuring the progress of energy
efficiency initiatives.
Targets can be expressed in different ways as long as
they remain SMART: specific, measurable, ambitious,
realistic and time-bound

11. 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

Replaced

13. 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.

14. CFL Replacement
PSTOCK_AVERAGE = Power average of the existing lighting bulbs in households
[W]
PBEST_MARKET_PROMOTED = Power of the market promoted efficient bulb [W]
nh = Average number of operating hours
Frep .– Correction factor taking into consideration that a proportion of bulbs
sold will not immediately replace existing bulbs; Frep≤ 1

15. 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).

16. Solar water heating in residential and tertiary buildings
USAVE = Average annual savings per m2 of solar panel, representing the
average heat production per m2 of solar panel [kWh/m2]
ŋstock _ average_ heating = Efficiency of the average stock water heaters or
heating systems in the year when the solar heater was installed.
Note: This is the efficiency of the existing installed stock and not the efficiency
of the solar heaters.
