  1. Experience with Energy Efficiency Monitoring in AustriaHerbert Lechner

  2. The big picture until 2009:increasing final energy demand …

  3. … since 2005 improving energy intensity final energy consumption per person final energy consumption per GDP

  4. Background for energy-efficiency monitoring in Austria • Directive 2006/32/EC on energy end-use efficiency and energy services • Adopted on 14 march 2006 • Purpose of the Directive • provide institutional, financial and legal framework that favors efficient use of energy • create the conditions for the development of a market for energy services and other energy efficiency improvement measures • Indicative energy savings target of 9% in 2016 • excluding the energy consumption of undertakings subject to the EU Emissions Trading Scheme (ETS) and of the military forces • Austria’s energy savings target 2016: 80.400 TJ;interim target 2010: 17.900 TJ

  5. Key issues of directive 2006/32/EC exemplary role of the public sector (procurement, refurbishment, etc.) distributors, distribution system operators, retail energy sales companies have to be included (covered with voluntary agreements) availability of qualification, accreditation and certification financial instruments and funds & funding mechanisms (home construction subsidies, Climate & Energy Fund, …) energy audits (households, companies) metering and informative billing (pilot projects, incorporated into electricity law)

  6. Implementation of Directive 2006/32/EC in Austria (1/2) Two main elements of implementation 1) State treaty between the Federal Ministry of Economy and the regional Provinces • Austria is a federal state, consisting of 9 provinces • Provinces have several legal competence in energy policy, especially in the building sector

  7. Implementation of Directive 2006/32/EC in Austria (2/2) 2) “Voluntary Agreements” between the Federal Ministry of Economy and interest groups of energy suppliers*) • electricity • gas and district heating • oil and coal • Target to reach by 2016: 10.900 TJ *) according to §6 2(b) – promotion of energy end-use efficiency and energy services by energy distributors, distribution system operators and retail energy sales companies

  8. Austrian Energy Agency acts as official monitoring body assigned by the Federal Ministry of Economy, according to Article 4 ofthe directive tasks • draft the 1st and 2nd National Energy Efficiency Action Plan (NEEAP) • monitor the implementation of the Directive by involving all relevant stakeholders in the monitoring process • develop bottom-up methods and top-down indicators to measure energy savings • report on the energy savings achieved • disseminate information

  9. For more informationhttp://www.monitoringstelle.at/

  10. Key task:development of bottom-up methods • why bottom-up methods? • at least 20% to 30% of the final inland energy consumption have to be proven via bottom-up calculation methods • monitoring of voluntary agreements • efficiency measure is compared to a baseline • dynamic baselines possible • energy consumption adjusted to external conditions (climate) and normalized • specific lifetime for each measure • possibility to take into account • rebound effect • spill over effect • uncertainty factors

  11. Formulas and values for bottom-up methods • Two kinds of formula • Default • Project specific • 4 level approach for formula and values • European default values and formula • National default values and default formula • Project specific formula and values • Measured (no formula, data on energy consumption before and after measure, normalized)

  12. Calculation and documentation of savings with bottom-up methods • general description of measure • quality criteria for each measure (e.g. which type of heat pump does the measure apply for – minimum requirements for efficiency of heat pumps and other technologies) • general calculation formula • (Number of units – free riders)* unit savings* rebound effect* spill over effect * uncertainty factor • Rebound, multiplier, free rider effects, uncertainty factors – not taken into account due to lack of consistant information • developed in a broad stakeholder process and documented in a ”methodology handbook”

  13. Online database (1/4) • for all measures for which bottom-up methods exist • open to all public institutions and energy suppliers the Directive applies for • accessible via www.monitoringstelle.at • registration necessary • activation of account by the AEA • user-friendly interface for data input: • default: number of measures • project specific: if additional information on measures is available

  14. Online database (2/4) • data entry • individually and directly by the user • data import by AEA possible (via Excel files) • user responsible for the data input • data is saved in the database and kept confidential by the EA • data evaluation • exported by the AEA (as Excel) • verification of the data entered by the AEA (plausibility check) • evaluated according to • user • region • type of measure • time series of yearly energy savings (Early Actions, savings valid in 2010/2016)

  15. Online database (3/4) • evaluation reports tailored to the needs of the user • process for setting up this monitoring system took about3 years (stakeholder process, development of methods and database) • set up of the database took about 2 years in total • cost of the process: approx. 100.000 € • data sources • only data input on measures which have somehow been initiated by the parties affected by the Directive • records kept on measures financed/subsidized by the federal state, federal governments or energy suppliers • e.g. home construction subsidies, alternative/efficient heating systems, reports on energy counseling, number of energy saving lamps distributed

  16. Online database (4/4) • advantages of the database • easy access after registration • standardized calculation of energy savings according to harmonized European bottom-up methods • flexibility due to adaptability of methods and default values • savings achieved are calculated and reported immediately • import and export of data via Excel possible • easy and cost-efficient data collection of energy-efficiency measures • challenges • double counting • creating methods for soft measures and mobility • dynamic baseline

  17. Bottom-up methods implemented in online database (1/2) • lighting • efficient street lighting • compact fluorescent lamps (CFL) in households • efficient lighting in service buildings • efficient lighting in hotels and restaurants • directly measured energy savings • energy audits (companies) • energy consulting (private households) • district heating • residential buildings • non-residential buildings

  18. Bottom-up methods implemented in online database (2/2) • building shells (new buildings, refurbishment, building elements) • residential buildings • non-residential buildings • cooling and air-conditioning • efficient cars • smart Meters in private households • heating systems • solar panels • replacement of gas- and oil boilers with condensing boilers in refurbished/non-refurbished buildings • heat pumps • circulating pumps • household refrigerators and freezers

  19. Results from the first monitoringTarget 2010: OK voluntary agreementstarget 2016: 10,9 PJ2010 reportedt: 3 PJ; included: 1,3 PJ

  20. Target 2016: can be reached with efforts comparable to 2008 - 2010

  21. Structure/measures of the calculated savings in 2010 (valid 2016)

  22. Most important measures listed home construction subsidies • thermal quality • efficient heating systems amendment of building codes to EPBD requirements legal framework for Combined Heat and Power energy counseling refurbishment of public buildings public procurement energy-efficiency programs for municipalities investment subsidies for companies smart metering and informative billing measures for sustainable mobility energy taxes research and development education, training labeling of appliances voluntaryaAgreements

  23. Most important measure: home construction subsidies and building codes

  24. Status of home construction subsidy schemes and building codes 2009 • social housing subsidy: total 2.892 mill. € • 956 mill. € for renovation • of which 564 mill. € for thermal renovation • heating energy demand • new residential buildings: 33 kWh/m2a (2006: 42) • deep renovation: 55 kWh/m2a (2007: 60) • 60% of supported heating systems in new buildings are based on renewables • 100 mill. € „renovation check“ (Federal program 2009) • 60/40 residential/non-residential buildings • residential: 20%, max. 5.000 € (heating systems 2.500) • support for 15.000 households, about 50% insulation • average subsidy: 4.300 €, feasible on-top of SHS • will continue 2011 – 2014 with 100 mill. € p.a. (70/30) • national grant scheme “Umweltförderung im Inland” (about 90 € p.a.) • one of about 20 different supported technologies is thermal insulation of non-residential buildings

  25. Energy Services Directive – outlookdraft for a new Directive presented in May 2011 • 9% energy savings target remains, indicative primary energy savings target of 20% by 2020 is added • refurbishment of public buildings has to be at least 3% p.a. • local authorities have to develop an energy-efficiency plan and introduce an energy management system • energy suppliers or distributors have to save 1.5% of their sales to final energy consumers (obligation but alternative models are possible) • obligation for large energy consumers (no SMEs or households) to carry out energy audits • obligation for individual metering and monthly billing on real consumption (electricity, heating with gas) from 2015 on

  26. Conclusions • first monitoring shows positive results for 2010 target and good perspectives to fulfil 2016 target • new EU-efficiency directive (planned to be implemented nationally until end 2013) will increase the demands on energy efficiency policy and establish efficiency obligations • the Austrian energy strategy intends to stabilise energy demand in 2020 at the level of 2005: this gives a further push for energy efficiency • from supply to demand focused energy policy:we have to reconstruct our energy systems
