Local Renewables Conference

Green Buildings and the Future of Urban Development

The fourth conference of the Local Renewables series focused on “Green Buildings and the Future of Sustainable Urban Development”. Organised by ICLEI and hosted by the City of Freiburg (Germany) from 27-28 October 2011, the conference looked at the evolving role of renewable energy in sustainable buildings and addressed the issue of energy efficiency, both from a technological and city development point of view.

Buildings make up 40 percent of the energy used in the European Union and account for 36 percent of Europe’s CO2 emissions. For this reason, the building sector plays a key role in combating climate change and offers local governments an excellent opportunity to meet their climate targets.

The Local Renewables 2011 Conference focused on:

  • The political framework for sustainable construction and urban planning from a European, national and regional perspective
  • Upgrading options for the existing building stock
  • Best practice examples of zero emission districts across Europe
  • Cutting-edge technologies and clever design for energy efficient  solutions
  • District heating and cooling
  • Financing models and mechanisms  - in particular the new Energy Efficiency Fund
  • Challenges in the value chain of energy efficient building
  • and much more…!
