The IEA energy efficiency template

The process and methodology

The 2008 and 2009 cycles

The Manual on Statistics for Energy Efficiency Indicators


The IEA energy efficiency indicators template


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


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)


Indicative planning of the 2009 cycle

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


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?


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


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: What is it all about?


A Manual on Statistics for Energy Efficiency Indicators: Practices questionnaire


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


Methodologies Received

184 Different Methods

Submissions from 34 countries and

60 unique organizations


A Manual on Statistics for Energy Efficiency Indicators: Content of the Manual
