12Evaluation Objectives

- ?????????????,???????????????
- ????
- ???????
- ?????????
- Primary objectives
- Document and measure the effects of a program and
determine how well an efficiency program met its
goals - Help understand why those effects occurred and
identify ways to improve current and future
programs - Other objectives
- Determining the cost-effectiveness of a program
- Documenting compliance with regulatory
requirements
13Evaluation is Part of the Program
Cycle???????????
- Evaluation results are used to make informed
decisions on program improvements and future
program designs and offerings - The program implementation cycle is one in which
programs are designed, then implemented, and then
evaluated - Using results of evaluations, programs are
re-examined for design changes and then modified - This cycle provides for a continuing process of
program improvement -

20Types of Evaluations????

- ??(kWh)???(kW) ???????????
- ??????????????(??????,?????????)
- ??????????
- ??????????????????????????????
- ?????????????????,????????????????
- Impact evaluations determine
- Energy (kWh) and Demand (kW) savings and avoided
emissions - Other benefits (such as health benefits, job
creation, and water savings) that directly result
from a program - Can also include cost-effectiveness analyses
- Process evaluations assess how well a program
was, or is, being implemented - Market effects evaluations estimate a programs
influence on encouraging future energy efficiency
projects because of changes in the energy
marketplace
21Impact Evaluations Total and Net?????????
- Total Energy Impact - The change in energy
consumption that results directly from actions of
participants in the DSM program. - Net Energy Impact - The total change in energy
use that occurred because of the DSM program - Total Energy and Net Energy impacts are not
usually the same - Net Savings/Total Savings Net to Total Ratio
(NTR)
- ???????DSM????????????????????

- ???/??? ????????(NTR)

22Net to Total Ratio????????
- Net Energy Impacts adjust the Total
- Energy savings that would have occurred without
the program - free riders
- (reduces total energy savings)
- Energy savings that occur without direct
influence of program - free drivers
- (increases total energy savings)
- Energy savings or energy increases due to change
in operations - for example, if a factory operates motors more
hours because cost of running the system is lower
with the measure installed - (reduces total energy savings)

- ??????
- Self-reporting surveys
- Information is reported by participants and
non-participants, without independent
verification or review. - Enhanced self-reporting surveys
- Self-reporting surveys, interviews and
independent documentation review and analysis. - Econometric methods
- Statistical models compare participant and
non-participants energy/demand patterns with
adjustments using econometric analyses and survey
input. - Stipulated net to total ratio Based on historic
information
24Process Evaluations????
- Recommendations can consist of suggestions for
changing - Programs structure
- How the program is implemented
- Program design
- Program delivery
- Program goals
- Should test for the use of best practices and
consider consumer satisfaction - Should assist timely feedback to make program
changes as needed or to review early findings. -

25Process Evaluations are Valuable when ????????,?
- The program is new or has many changes
- Energy savings are less than expected
- There is low participation by consumers and other
participants in programs - Program has a slow start-up
- Participants are reporting problems
- Program appears to not be very cost-effective
-

26Process Evaluation Methods??????
- As with impact evaluations, process evaluation
requires a plan - It is best if the process evaluation is done by a
group independent of the program implementation - Process evaluation is done with data collection
from - Surveys
- Individual interviews
- Group interviews
- Written surveys
- Observation, measurement and analyses

27Market Effects Evaluation??????
- Market Effects Study evaluates increases in the
adoption of energy efficient products, services
in the market. - Market effects evaluations determine whether the
market is changing. Example What types of high
efficiency products are generally available, such
as CFLs? - Market effects evaluations usually consist of
surveys, reviews of market sales data, and
analysis of the survey results and collected data.

33MV Options MV ??
Options A and B are retrofit-isolation
methods ??A?B??????? Options C and D are
whole-facility methods ??C?D??????? The
difference is where the boundary lines are
drawn ??????????
34MV Options MV ??
The Options differ in their approach to the
level, duration, and type of baseline and
reporting period measurements. Options A and B
measurements are taken at the end-use system
level (e.g., lighting, motor system) Option C
evaluations are conducted at the whole-building
or whole-facility level. Option D evaluations,
which involve computer simulation modeling, are
also made at the system or the whole-building
level.

In terms of type of measurement Option A -
involves using a combination of both stipulations
and measurements of the key factors needed to
calculate savings in engineering models. Options
B - and C involve using data collected from
spot, short-term, and/or continuous measurements
in engineering models (Option B) or regression
analyses (Option C). Option D - may include
spot, short-term, or continuous measurement data
to calibrate computer simulation models.
36Example IPMVP in Evaluation Application -
California??IPMVP?????-?????
- In the 2006 California Energy Efficiency
Evaluation Protocols - MV plans must adhere to
the IPMVP. - A basic level of MV is defined as involving a
statistically adjusted engineering model with
metering/monitoring per IPMVP Option A. - An enhanced level of rigor is also defined that
would be based on IPMVP Options B (retrofit
isolation) or D (calibrated simulation). - Details are defined in a program MV plan that is
reviewed on a case by case basis. -
