Transcript of "Background and Scope for Building Envelope"

  1. 1. Background and scope of the building envelope Yamina SAHEB Yamina.saheb@iea.org © OECD/IEA 2011
  2. 2. Buildings sector share of the total finalenergy consumption 16 000Mtoe Other 14 000 Buildings 12 000 Transport Industry 10 000 8 000 6 000 4 000 2 000 0 2007 Baseline 2030 Baseline 2050 BLUE Map 2050 © OECD/IEA 2011
  3. 3. Background Buildings are complex systems  Holistic approach for the envelope  Policy package  Regulatory instruments (codes and MEPs) and their enforcement  Labels and certificates and their enforcement  Economic instruments (financial, tax, market based instruments and direct investments)  Efficient technologies for the envelope  Envelope  Insulation for walls and roofs  Efficient windows  Cool roofs for hot climates  What else?  HVAC equipment and appliances (excluded) © OECD/IEA 2011
  4. 4. Building Types Residential (new and existing ones?)  Single family residential  Multi-family residential  Other residential (mobile homes…???0 Non-residential (new and existing ones?)  Office building  Hotel  Education building  Public assembly (community centres, meeting halls..)  Health care  Mercantile & Service  Institutional lodging (retirement homes…)  Other non-residential (factories,…????) © OECD/IEA 2011
  5. 5. Energy perspective Energy consumption in operation phase only? Embodied energy? Which end-uses to include in the energy balance?  Heating and cooling only?  Lighting?  Ventilation?  Other end-uses to include? Other criteria and impacts to consider? © OECD/IEA 2011
  6. 6. Key questions to answer by the end ofthe workshop Which policy packages are the most effective in terms of energy savings? New and existing buildings Different building types Regional differences? Can we prioritize policies and how? Main barriers and how to overcome them? International collaboration? © OECD/IEA 2011
  7. 7. Key questions to answer by the end ofthe workshop What are the most efficient technologies New and existing buildings Different building types Regional differences? Cost effectiveness? Barriers to efficient technologies deployment International collaboration Is there a timing issue? 2 separate publications; one on policies and one on technologies or one single publication on building envelope? © OECD/IEA 2011
