An annual data collection cycle
Templates sent to countries
Countries fill them in and send them
back
IEA analyses the submissions
and asks questions
Based on the answers
received, the IEA finalises the
templates
The data is uploaded in the
IEA Energy Efficiency Indicators database
The final templates are
sent back to the countries
The data is
available to
all IEA
analysts
Some
further
questions
may arise
Countries
can ask the
IEA to obtain
the data
from
ODYSSEE
Non-EU
data is
shared with
ODYSSEE

Thorough data quality checks
Internal consistency
Consistency with IEA energy balances
Plausibility
Gross vs Net Calorific Value
Coverage / definitions
We try to understand “why” to help countries overcome the difficulties they face in providing quality data

Industry Data from the IEA energy balance
ODYSSEE used to fill the missing information
Time series analysed and corrected to account for changes in reporting methodology or coverage
Services Data from the IEA energy balance if end-use level data
are not available from ODYSSEE or country submission
Residential Data from country submission
Data from ODYSSEE
Transport Data from country submission
Data from ODYSSEE
Unless the
countries
asked us to
use a different
source (e.g.
Canada, US)

2008 cycle finalised
Energy Efficiency Indicators Database finalised data for the years 1990 to 2008
for a number of countries, data for the years 1990 to 2009 for the industry sector, using the statistics received through the five IEA Annual Questionnaires for 2009
Out of 28 IEA countries, 16 countries with sufficient coverage and quality for 1990 to 2008 for all of the four sectors
Residential
• 18 countries
Services
• 4 countries (breakdown)
• 21 countries (total)
Manufacturing
• 19 countries
Transport
• 18 countries

First update since
the 2009 IEA Ministerial
the redesign of the template
the template has become an official country submission to the IEA
We have worked hard to Improve the dialogue with countries and with the ODYSSEE
network
Improve accountability
Improve transparency

Some of the main gaps/issues with the data
No cooling degree days available for EU countries
Important differences between the data reported for energy efficiency indicators and the IEA energy balances for some countries
Confusion between diffusion rate of appliances and ownership rate
Occupied dwelling: occupied dwelling, permanently occupied dwelling or households
Differences in the industry and value-added coverage
© OECD/IEA 2011 © OECD/IEA, 2010
Some of the main gaps/issues with the data
Unclear if all countries are using the same methodology for the calculation of heating degree-days
Differences between countries in reporting of biofuels components
No distinction between passenger and freight for ships and airplanes
Major break in series identified (as a result of methodology change, or discontinued surveys)
Residential end-use breakdown are inconsistent (e.g. lighting included in appliances)

The next steps
IEA – ENERDATA meeting to discuss Differences in definitions between the ODYSSEE and the IEA
template Data checks performed by both organisations Estimation techniques adopted/suggested in ODYSSEE and IEA
Improving the documentation provided to users of the IEA template
Working always more closely with countries to improve the quality and the coverage of their data
Presenting some preliminary results from the 2009 cycle at an energy efficiency indicators workshop at the IEA in March 2012

A Manual on Statistics for Energy Efficiency Indicators: Context
The IEA Ministerial meeting Acknowledge the importance of developing meaningful
indicators to support policy development
Commit to report data supporting the development of indicators annually through the IEA template
Requests from member and non-member countries to provide guidance on: What indicators to use
What data are needed to support the development of these indicators
How to build these indicators
But how to collect the data?
© OECD/IEA 2011 © OECD/IEA, 2010
A Manual on Statistics for Energy Efficiency Indicators: Collaborative effort
Building on the success of the Energy Statistics Manual Support countries in developing/maintaining high quality energy statistics In collaboration with Eurostat Now available in 10 languages
In close cooperation with ODYSSEE network APEC Member and non-member countries Industry associations Companies
Countries inputs are an integral and important part of the development of the Manual
The goal is to meet the expectations of all stakeholders involved in gathering data to support the development of
energy indicators
© OECD/IEA 2011 © OECD/IEA, 2010
The manual will provide information on how to collect the
data required to develop energy and energy efficiency
indicators
The Manual will not be a reference manual on energy
statistics or on indicators
However, it will be difficult to talk about the data behind the
indicators without briefly touching upon what are indicators
and why they are part of any sound energy efficiency policy
The main focus will really be on how to collect the data
needed to build those indicators.

A Manual on Statistics for Energy Efficiency Indicators: The methods covered
The strategy or method to be adopted depends on several factors (the data needs, the country specificities, the priorities, the time and resources available)
The most frequently used methods/sources can be grouped in four main categories Survey
Metering/measuring
Modelling
Administrative sources
Analysis of the answers to the practices questionnaire provides indications on what works best for specific data points under specific conditions
