1 Sustainable Energy Policies Examples in Austria DI Gerhard Bayer Austrian Society for Environment and Technology Österreichische Gesellschaft für Umwelt und Technik- ÖGUT 1

2 Austrian Society for Environment and Technology Mission founded 1985 as a non-party platform non-party association, platform for economic, political and environmental interests support environmental friendly solutions 2

3 Members and institution 80 members from: environment, e. g. Greenpeace, Global 2000, WWF business, e. g. Federal Economic Chamber, Financing Institutes administration, e.g. Ministry for Environment., M. f. Econom. Aff., M. f. Transport, Innovation and Technology, City of Vienna, County Lower Austria Institution 24 employees financing: 85% by projects, 15% by member fees 3

4 activities strategy consulting/ recommendations policy advice pilot and demonstration projects for environmental technologies management of public environmental support programme studies/publications working groups with stakeholders 4

5 Energy situation in Austria Bruttoinlandsverbrauch % for heating and cooling! PJ Standmotoren 3% 15% Industrieöfen 13% Beleuchtung und EDV Elektrochemische Zwecke 0% Raumheizung und Klima 30% Dampferzeugung 7% Verkehr 32% 5

6 Feasibility study: covering heat and hot water in Austria by 100% renewable energies Energieverbrauch Raumwärme und Warmwasser und Aufbringung aus Erneuerbaren 350,0 350,0 300,0 300,0 private Haushalte 250,0 öffentliche und private Dienstleistungen produzierender Bereich 250,0 Energieverbrauch in PJ 200,0 150,0 Landwirtschaft Aufbringung aus Erneuerbaren insgesamt 200,0 150,0 100,0 100,0 50,0 50,

7 100 % renewable for heating and HW How can this work? Reducing heating energy demand Thermal retrofitting of buildings: - retrofitting-rate from 1%/a to 3%/a ( HH/a to HH/a) - High quality of retrofitting (30 60% heating energy reduction) Rate of new buildings: ongoing trend 1%/a, high energy efficiency standard (Low energy or passiv house standard) Framework: continuing consumption trends; raising m²/capita 7

8 100 % renewable for heating and HW How can this work? Increasing solar energy for hot water private HH: increase from 4,1 PJ/a (2005) to 25 PJ/a (2030) 60% of hot water by solar Industry: thermal solar for low-temperature use (< 250 C) from 0,5 PJ/a (2005) to 6 PJ/a (2030) Use of CHP at biomass-power plants Heat pump for certain applications (single family home in passive house standard) 8

9 Heat supply by 100% renewables Wärmeaufbringung aus Erneuerbaren in PJ Aufbringung aus Erneuerbaren in PJ 250,0 200,0 150,0 100,0 50,0 Aufbringung aus Solarthermie gesamt Aufbringung gesamt Wärmepumpe (Brauchwasser und Heizung) Aufbringung gesamt Fernwärme aus Biomasse KWK Aufbringung gesamt aus Biomasse (ohne KWK)

10 Example: Program Building of Tomorrow State support program Building of Tomorrow Support innovation of sustainable building technologies - Focus on Energy Efficiency and Renewable Energies Support cost reduction of sustainable technologies Support market penetration Project results are public available on data base Website: 10

11 Example: Energy Efficiency power plant Virtual energy efficiency power plant EU-project EffCoBuild: Database on ertes-europa/effcobuild.php 11

12 Example: Energy efficiency power plant Example of a virtual energy efficiency power plant in Vienna Reduction of heating energy demand by 80% 12

13 Example: Energy Efficiency power plant Barriers: for policy it is easier to build 1 x MW power plant than 1000 efficiency projects x 1 MW producing is more sexy than saving (opening ceremony!) Strengths: Energy efficiency power plants can be build everywhere in the country saving transmission and distribution costs (investments and maintaining) 13

14 Passive house standard 300 Annual heat requirement for buildings in kwh/m²a Household energy Ventilation energy Hot water Heating Old buildings New minimum Energy saving Low energy Passivehouse standard house building 14

26 EU-policies on Energy Efficiency buildings Das Europäische Parlament fordert die Kommission und Mitgliedstaaten auf, bei Energieeffizienzanforderungen an Gebäuden das Potenzial voll auszuschöpfen Als verbindliche Bestimmung wird vorgeschlagen, dass alle neuen Gebäude ab 2011 nach Normen für Passivhäuser oder gleichwertigen Normen für Nichtwohngebäude gebaut werden müssen. Entschließung des Europäischen Parlaments vom 31. Januar 2008 zu dem Thema "Aktionsplan für Energieeffizienz: Das Potenzial ausschöpfen" 26

28 Energy Performance Contracting (EPC) Participants at Energy Performance Contracting Contractor (private company in the sector energy savings) Building owner (e. g. municipalities, ministries, counties 28

29 Energy Performance Contracting (EPC) cash flow: yearly pay-back rate contractor (private company in the sector energy savings) investments building owner (e. g. municipalities, ministries, counties) 29

30 Energy Performance Contracting (EPC) Strengths: company offers best technology (cost/benefit) company has self interests in optimising energy saving results all in one hand responsibilities pre-financing of contractor (if needed) weaknesses: more work for contract design (EPC only for larger projects ) re-evaluating, when user behaviour changes during the contract period 30

31 ECP example A: guaranteed savings overreached EPC-example A, savings overreached guaranteed savings Example A: investments: 700 units savings guaranteed: 100 units/a contract duration: 7 years effectively savings payment rate effectively savings: 130 units/a sum of all payments = 700 units 0 1. year 2. year 3. year 4. year 5. year 6. year 7. year 31

32 ECP example B: guaranteed savings not met EPC-example B, savings not met guaranteed savings Example B: investments: 700 units savings guaranteed: 100 units/a contract duration: 7 years effectively savings effectively savings: 70 units sum of all payments = 490 units payment rate 0 1. year 2. year 3. year 4. year 5. year 6. year 7. year 32
