  • 1. © OECD/IEA 2013 Clean Energy Solutions Center IEA Buildings Book Launch Didier Houssin and Marc LaFrance International Energy Agency
  • 2. © OECD/IEA 2013 IEA/SPT Flagship Publication, Energy Technology Perspectives  6 C Scenario – business-as-usual; no adoption of new energy and climate policies  2 C Scenario - energy-related CO2-emissions halved by 2050 through CO2-price and strong policies Source: Energy Technology Perspectives 2012 6 C Scenario emissions 58 Gt ------------> 2 C Scenario emissions 16 Gt ------------>

  • 4. © OECD/IEA 2013 Transition to Sustainable Buildings Key messages:  Energy demand in buildings set to rise 50% by 2050  40 EJ energy savings potential (25% reduction over 6DS) • Equivalent to current energy use in India and Russia  Stringent codes required for all new buildings  Aggressive measures to encourage renovation key as 50% of existing buildings will still be standing in 2050  Majority of technologies needed are already commercially available in OECD countries
  • 5. © OECD/IEA 2013 Priority Recommandations Note: Recommendations limited to top two for technology and policy, all items could be relevant for most countries. Red indicates immediate priority, while gold indicates medium-term priority ASEAN Brazil China European Union India Mexico Russia South Africa United States Technology Advanced envelope – cold climate Reduced cooling loads – hot climates Heat pumps Solar thermal More efficient use of biomass Policy Building codes with supporting infrastructure Appliance and equipment standard Deep renovation of existing buildings Zero-energy new buildings
