Kaukonpäivä 2014: Energy efficiency building envelope, IEA Marc LaFrance

  1. 1. IEA Technology Roadmap: Energy Efficient Building Envelopes Opportunity for Modern District Heating Systems Marc LaFrance International Energy Agency 4 March 2014 Kauko’s Day Helsinki Energy © OECD/IEA 2014
  2. 2. Importance of Buildings Sector Other sectors 4%  Largest end-use sector  1/3 carbon emissions 4% 11% Coal 22% Transport 30% Oil Natural gas  50% of electricity Buildings 35%  Major portion of GDP Electricity 5% Industry 31% 28% Commercial heat 30% Renewables  Stock opportunities:  75% - 90% of OECD building stock still in service by 2050  Large population growth in developing world will drive new floor area that needs to be efficient (2.5 billion more by 2050) © OECD/IEA 2014
  3. 3. Transition to Sustainable Buildings: Strategies and Opportunities to 2050  The overall ETP strategy for buildings  Global and regional analysis, energy savings and emissions reduction forecasts  Technical opportunities and recommendations: envelope; heating and cooling; appliances, lighting and cooking  Policies to transform buildings © OECD/IEA 2014
  4. 4. Technology Roadmaps & Policy Pathways  Technology Roadmaps  Policy Pathways © OECD/IEA 2014
  5. 5. Technology Roadmap Energy Efficient Building Envelopes  Construction transformation strategy  Provides technical, economic and strategic framework  Assessment of high priority areas for 12 regions of the world  Policy criteria and evaluation © OECD/IEA 2014
  6. 6. Transformation to Low-Energy Buildings © OECD/IEA 2014
  7. 7. Envelope Savings Potential © OECD/IEA 2014
  8. 8. Insulation Opportunity  Very stringent U-values for electric resistance heaters in Sweden, and Canada’s coldest climate zone  IEA recommending goal for average wall and roof U-values ≤ 0.15 W/m2K cold climate, ≤ 0.35 W/m2K hot climate based on LCC © OECD/IEA 2014
  9. 9. Validated Air Sealing  Validated air sealing is a critical measure for building codes and renovation  Majority of energy performance certificates do not require validation  More research needed to offer more affordable testing and solutions (mostly for developing markets) Source: Oak Ridge National Laboratory © OECD/IEA 2014

  14. 14. Criteria for Policy Assessments, IEA Perspective Policies © OECD/IEA 2014
  15. 15. Advanced Envelope Synergistic with Modern District Heating  Lower building heating loads is fully compatible with modern, 4th generation DHC systems  Lower operating temperatures reduce distribution losses  Lower heating loads allow for system expansion without increase in distribution capacity  Holistic approach with end-user considerations will be essential in competitive market with individual heating system opportunities (e.g. heat pump systems) © OECD/IEA 2014
  16. 16. Tracking Progress – Next Steps  Much more data is needed (e.g. new technology adoption rates, market share of zero-energy buildings, district heating and CHP, etc)  More specific performance criteria needed even for most advanced regions (e.g. EU specifications for renovation in public buildings)  IEA is considering a new building’s partnership (for policy assessment, to improve data and modeling, and to enable deployment) © OECD/IEA 2014
  17. 17. Framework for Partnership © OECD/IEA 2014
  18. 18. IEA Sustainable Building Partnership/Collaboration  Establish expanded and more formal partnership with wide range of stakeholders, NGO’s, Academia, Governments, Industry, Trade Associations to improve data and expand modeling capability  Assess policy formulations and timing, ranging from standards enactment, deep renovation, building codes, integrated DHC, zero energy buildings, etc  Work to establish sponsors to allow for IEA Building dedicated resources, increase staff, allow for event participation, workshop support, and general enabling of deployment  Next steps – hold small consultations with key stakeholders to establish a base for initiating a partnership; hold large stakeholder workshop later this year © OECD/IEA 2014
  19. 19. Key Focus for Action  Greater deployment of proven technology in developed countries  Introduction of mature products and technologies to developing markets (e.g. infrastructure – skills, product availability, performance metrics, etc)  Integrated advanced building envelope renovation with modern DHC  R&D to improve performance, reduce cost and provide greater overall return on investment © OECD/IEA 2014
  20. 20. IEA CHP/DHC Collaborative – Phase III  Country Score Cards – Finland, Korea, Japan updated 2013; India, US - ongoing Learn more at http://www.iea.org/chp/countryscorecards/  Analysis report – CHP and DHC solutions for a clean energy system - 2Q 2014  Policy strategies to overcome CHP/DHC deployment barriers throughout,  Project development:  Technology selection  Financing mechanisms  System operation:  High interconnectivity, bi-directional energy flows  Smart business mechanisms  Case studies  Next Collaborative’s Strategic workshop 27-28 May Paris  Phase IV (2015-2016) programme  Focus on flexibility benefits  integration of greater renewables, bridging thermal and electricity systems, smart thermal networks.  Lead IEA Contact – Araceli Fernandez-Pales, araceli.FernandezPales@iea.org © OECD/IEA 2014
