Proposal for an alternative approach

Workshop – Bottom-up measurement and verification of energy efficiency improvements: national & regional examples Brussels, 3 March 2005


Criteria for measuring and verifiyingenergy efficiency improvements

Significant amount of energy consumption need to be within the scope of the methodology

Compatibility with existing or future energy efficiency measures on EU-level is desirable (e.g. Commission WP 2005)

Survey of measurement/data should be cost-effective and transparent (as far as possible based on existing measurement/data)

Definition of measurement/data should be standardised within EU

Contribution to the harmonisation of the internal market

...

Discussion: Which methodology meets the criteria for measuring and verifying energy efficiency improvements best?


Energy Services Directive: Questions on evaluation

Can the proposed methodology evaluate a top-down target?

Are the required measurement/data already available?

How much effort is necessary for the measuring and how will transparency be guaranteed?

Can experience and approaches be transferred from Member State to Member State?

Can the proposed method contribute to harmonise the calculation-methods within EU?

Proposal for Energy Services Directive raised several questions:

Questions were drivers for the development of alternative ideas


The Idea: Approach on the basis of indicators

Energy-efficiency-indicators for substantial energy conversion markets do already exist or are being implemented (e.g. domestic appliances: labels, household heat: energy pass 2006)

Simplified and cost-effective statistical calculation with relatively high transparency can be achieved

Implicit harmonisation within the internal market

A methodology on the basis of energy-efficiency-indicators can be an appropriate way to meet the criteria for measuring and verifying energy efficiency improvements


Alternative proposal – Overview

Not one energy efficiency market but many markets of energy conversion requirement of customised targets and measures

Initial point

More than 70 % of the energy end-use consumption in Germany is available

Step 1: Defining sub-segments

Step 2: Determining indicators

Indicators as a degree for the energy efficiency in a sub-segment

Step 3: Setting benchmarks

Benchmarks on the basis of indicators as a criteria for the requirement of the execution of end-use efficiency measures


Alternative proposal – Markets of energy conversion

1. Market for domestic appliances1.1 White goods1.2 Entertainment- / information technology1.3 Lighting

2. Market for household heat technology2.1 Heating2.2 Hot water production2.3 Air conditioning2.4 Ventilation

3. Market for industrial furnaces

4. Market for motor and drives in the industry

5. Market for public institutions5.1 Schools / public administration5.2 Hospitals5.3 Swimming baths5.4 Street lighting

6. Market for transport services

More than 70 % of the energy end-use consumption in Germany


Alternative proposal – Indicators

Indicators reflect energy efficiency for individual applications in the respective market of energy conversion

Indicators allow for consideration of the complex market structure and the various customer requirements

Choice of indicators influence evaluation-effort Sensible choice of indicators has to orientate on transaction costs

High transaction costs – labels, standards, codes of conduct, e.g.

Low transaction costs – audits, services (e.g. contracting)

Determining of indicators for 25 Member States is complex

Establishing of an European brain trust (e.g. Comitology in line with CHP-Directive)


Alternative proposal – Indicators (example)

Indicators reflect energy efficiency for individual applications in the respective market of energy conversion.

Market of energy conversion: Domestic appliances

Sub-segment: White goods

Use: Cooling and freezing

Indicator: %age market share of sold A, A+, A++ -appliances

Example:


Alternative proposal – Benchmarks

Benchmarks on the basis of indicators serve as a criteria for the requirement of the execution of energy end-use efficiency measures.

fulfilment

No measures for increasing energy efficiency in this application market required

Non-fulfilment

Measures for increasing energy efficiency in this application market required

Benchmark: arithmetic average of the upper third of the Member States for the indicator „%age market share of sold A, A+, A++ cooling units“

Example:

Dynamic sampling of the benchmark by catching-up processes of the MS


Alternative proposal – Market specific efficiency requirements

MS1 X

1 = Requirement for MS1

MSn X

n = Requirement for MSn= 1

n+1 = Requirement for MSn+1 < 1


Alternative proposal – Pros and Cons

Consideration of the complex market structure and the various customer requirements, allow for implementation of goal-orientated measures, where call for action is identified (market specific approach)

Relatively limited evaluation effort (indicators of significant markets existing) Harmonisation of energy-efficiency-levels within EU Implicit consideration of „early actions“ is possible

„Technical“ questions have to be addressed on the European level

Advantages:

Disadvantages:
