  1. From Kyoto to Copenhagen – From Energy Waste to Clean Energy use in Buildings Cutting down energy consumption in buildings Towards a factor 4 policy for buildings 10 October 2009 Copenhagen International Energy Agency IEA Jens Laustsen Policy Analyst for Efficiency in Buildings © OECD/IEA, 2009

  2. Key messages • Energy efficiency is a critical part of a sustainable energy future • Buildings energy use can be reduced dramatically alone with existing solutions • A reduction to ¼ of BAU in 2050 is rational and economic reasonable (Factor 4) • IEA 25 recommendations provide direction – high emphasis on buildings • W.I.N = World-wide Implementation Now © OECD/IEA, 2009

  3. Energy efficiency – critical part of sustainable energy future Buildings: Can deliver larges reductions in CO2 emissions at low costs

  4. Reductions in energy-related CO2 emissions in the climate-policy scenarios 45 550 450 Policy Policy Gigatonnes Scenario Scenario Nuclear 40 9% CCS 14% Renewables & biofuels 23% 35 Energy efficiency 30 54% 77 % of the solution ! Energy Efficiency in buildings is a central part of this 25 20 2005 2010 2015 2020 2025 2030 Reference Scenario 550 Policy Scenario 450 Policy Scenario While technological progress is needed to achieve some emissions reductions, efficiency gains and deployment of existing low-carbon energy account for most of the savings. © OECD/IEA, 2009

  5. Energy efficiency in buildings is climate change abatement at low costs • Why ? - They are feasible on long term ! • Many recent studies shows exactly the same trends ! • But maybe we don’t take these initiatives far enough ! • How far can we take energy efficiency in buildings at rational costs ? • Examples from ongoing IEA study !

  14. Cut Energy Waste Going new ways – or finding old solutions

  15. Cut energy waste in buildings ! • There is a large potential: • We have to go new ways • Use control systems • and new solutions • But we also need to look at • history / tradition • Training of architects, engineers, installers, constructors is essential • Energy efficiency needs to be at the front page ! An example ! © OECD/IEA, 2009

  21. Study on Energy Efficient Buildings If very best practice examples and policies were implemented globally and fast: • Energy use for buildings (heating, cooling, ventilation and hot water) could be reduced far beyond 50 %. • 75 % reduction compared to business as usual would probably both be possible and rational. • Book to document this will be out early 2010. • Such and implementation of energy efficiency in buildings would have massive impact on: • Security of supply, • CO2 emissions, • Global health, • Investments in supply sector, • Would crate millions of new jobs. • Increased research and deployment can increase this potential. © OECD/IEA, 2009

  22. 25 energy efficiency policy recommendations across 7 priority areas 1. Across sectors 1.1 Measures for increasing investment in energy efficiency; 1.2 National energy efficiency strategies and goals; 1.3 Compliance, monitoring, enforcement and evaluation of energy efficiency measures; 1.4 Energy efficiency indicators; 1.5 Monitoring and reporting progress with the IEA energy efficiency recommendations themselves. 2. Buildings 2.1 Building codes for new buildings; 2.2 Passive Energy Houses and Zero Energy Buildings; 2.3 Policy packages to promote energy efficiency in existing buildings; 2.4 Building certification schemes; 2.5 Energy efficiency improvements in glazed areas. 3. Appliances 3.1 Mandatory energy performance requirements or labels; 3.2 Low-power modes, including standby power, for electronic and networked equipment; 3.3 Televisions and “set-top” boxes; 3.4 Energy performance test standards and measurement protocols. 4. Lighting 4.1 Best practice lighting and the phase-out of incandescent bulbs; 4.2 Ensuring least-cost lighting in non-residential buildings and the phase-out of inefficient fuel-based lighting. 5. Transport 5.1 Fuel-efficient tyres; 5.2 Mandatory fuel efficiency standards for light-duty vehicles; 5.3 Fuel economy of heavy-duty vehicles; 5.4 Eco-driving. 6.

  23. Conclusions • Energy efficiency in buildings is www: • Consumers win because they get lower fuel cost and lower total costs over time, increased comfort. • Business win because it creates activity and new jobs locally. • Governments win because it implements climate policy goals, improves security of supply, improves economy and health. • Potential is enormous. • Can contribute substantial to climate abatement policies. • A reduction with factor 3 or 4 is possible alone with known solutions. • Policies exist but need larger scope and global implementation. • Many barriers to overcome. • EE in buildings is cost efficient and it will save large investments and costs in supply. • EE in buildings will have many additional benefits: health, security of supply, creation of employment. • Start with the 25 existing IEA recommendations - already endorsed by the G8 and large developing countries. • We need W.I.N Much more can be done – both in new and existing buildings © OECD/IEA, 2009 © OECD/IEA, 2009
