Start standardization indicator and measurebased methodes at CEN/CLC in 2006

• CEN Workshop Agreement CWA 15693 ‘Saving lifetimes of Energy Efficiency Improvement Measures in bottom-up calculations’ published in 2007. A list of saving lifetimes as an annex to the ESD

• CEN/CLC JWG 4 on energy efficiency and savings calculation developed: EN 16212 Energy Efficiency and Savings Calculation, Top-down and Bottom-up Methods, published in 2012

The standard builds on the results of European projects: EMEEES on top-down and bottom-up calculation

methods to monitor the ESD savings ODYSSEE on energy efficiency indicators that can be

used to calculate top-down energy savings for the EU member states


ISO TC 257 energy savings evaluation

• First meeting in 2011 in Beijing • Chinese initiative and leadership• In Europe we saw the possibility to transfer the EN

16212 standard to the international level under the umbrella of the TC 257

• France (AFNOR) and The Netherlands (NEN) offered the Chinese leadership their support as co-chair and co-secretary.

• Scope TC : ‘Standardization in the field of energy savings through general technical rules and specific methodologies for the calculation of energy savings in projects, organizations and regions, and guidance on measurement, verification, and assessment of data quality as it relates to these calculations.’

New workitems

• AWI 20364 ‘Energy Savings Evaluation -- Economics and financial evaluation of energy saving projects’ (Iran)

• AWI 20366 ‘General quantification methods for ex ante or expected energy savings’ ( France)

• AWI 20375 ‘Technical guidelines for evaluation of energy savings of thermal power plants’ (China)

• AWI 20376 ‘General guidelines for selecting energy savings evaluators’ (China)

• AWI 20619 ‘Calculation methods for energy savings’ (France) regarding decomposition of energy savings


Scope ISO 17742

A general approach for energy efficiency and energy savings calculations with indicator-based and measure-based methods for the geographical entities countries, regions, and cities. It is about all end-use sectors Not for: • the energy supply sectors, such as power plants,

refineries, and coal mines.• calculating energy savings of individual households,

organizations, companies, or other end users


3-11-2015

Used methods

Indicator-based (ISO) = Top-down (EN)Measure-based (ISO) = Bottom-up (EN)

Characteristics of Indicator-based method:– Indicators per targeted energy consumption (e.g. space heating households)– Indicator relates energy use to socio-economic quantity (e.g. dwellings)– Change in indicator value => energy efficiency and savings – Explanation of energy trends: volume/structure/savings

Characteristics of Measure-based method:– Focus on saving measures at energy users level – Policy (deliberate) measures and programmes stimulating saving measures– Extra savings due to policy > correction for autonomous savings/free riders,

etc.– Expected (ex-ante) and observed (ex-post) policy savings


Complement of ISO 17742: AWI 20619 on decomposition

1. To complement ISO 17742 standard with a standard on calculation of explaining factors for energy consumption through decomposition. It includes energy savings currently calculated in ISO 17742.

2. To translate energy savings in an aggregated index as an alternative of energy intensity trend (applied in Europe as ODEX)

3. To calculate the structural effect of the energy intensity in order to clean out these effects in the energy intensity to get a better proxy of the energy intensity

Possible application of standard (1)

Stakeholders and 17742 standard• Energy consumers (households, enterprises)• Energy suppliers (system efficiency, CHP)• Energy distributors (saving obligations)• Energy auditors / benchmarking• Energy service companies (ESCO)• Investors in saving projects (Banks)• Energy agencies / program managers• Manufacturers of energy using equipment / vehicles / building sector • Evaluation organizations (EVO)• Administration of countries, regions and cities• Super-national bodies (EU, Latin American Energy Organization (OLADE),

ASEAN Centre for Energy (ACE)• International bodies (UN, WB, WTO, IEA, WEC)



Indicator Based methods• Compliance with efficiency requirements for devices (Eco-design, EPBD, cars)• Insight on energy (savings)trends at country level, • Check on formulated national targets (total savings)• Comparison between countries > effectiveness of policy• International benchmarking for industry sectors• Facilitating international agreements on savings:

– Devices– Sectors (cement, steel)– Countries (UNFCCC)

(Mainly ex-post for realized savings)

Measure Based methods• Calculations by energy users for saving investments• Calculations as part of EES • Evaluation of realised savings as part of EMS• Savings effect of (utility) programmes• Savings effect of specific policy measures• Evaluation of savings due to obligation schemes (ESO / WCS)• Check on targets for extra savings due to policy (National Energy Efficiency

Action Plans, NEEAP)• Effect of Nationally Appropriate Mitigation Actions (NAMAs) as part of

UNFCCC agreement

(Both ex-ante (expected) and ex-post (realised) savings)



COB 21, Paris 2015 International agreement on Intended Nationally Determined Contributions (INDCs) for GHG• Targets for energy intensity decreases > check realization:

– national > IBM– per sector > IBM– per subsector (e.g. cement, steel) > IBM

• Targets for energy savings > check realization:– national (total savings) > IBM– per sector (total savings) > IBM

• Targets for extra savings with policy > check realization:– National (extra savings compared to baseline) > MBM– Per sector / targeted energy use > MBM

• Targets for implementation of policy > calculate effect:– Per policy measure / programmes / overall policy > MBM

• Targets for NAMA’s (saving measures) > calculate effect:– Per saving measure / overall > MBM
