Oekosan 09 - International symposium for high-quality energetic renovation of large-scale buildings

From October 7 to 9, 2009 the AEE INTEC has organized an international symposium "Ökosan 09". The emphasis of the symposium was the communication of (partial) results of running and closed cooperation projects by leading technical experts dealing with the retrofit of large-scale buildings.

Summary

Starting point / motivation

A major part of the energy consumption of the member states of the European Union is consumed by the building sector. Especially in the Central-European moderate climate zones nearly one third of the total energy consumption is spent on space heating. In the field of building renovation the potential savings for primary energy use is much higher than in the field of new buildings. Therefore in the future, essential energy savings can be achieved only by high performance renovation of the building stock. In order to obtain sustainable results new innovative developments and renovation alternatives have to be discussed. Very important in this connection is the aspect of their economical practicability.

Objectives and contens

Within a three-day international conference these topics on the building stock and approaches for solutions will be analyzed and revealed with representatives of policy, economic and research.  Parallel with the conference a technical exhibition will take place. Within these three conference days numerous companies will present their innovations and new trends to the visitors, in all fields of building construction and retrofitting. Additional to the technical presentations best practice examples and concepts of implemented or running projects, technical components and innovative materials will be presented in the frame of a poster exhibition. 

Objective of the symposium was to contribute to the know-how-transfer of the state-of-the-art of research and development for concerned target groups. So the conference contributed to ensure future energy supply and to reduce greenhouse gases caused by emissions of the building sector.

The topics of the symposium ´09 had been:

  • Energy efficiency in the e5-municipalities
  • Frame conditions for an ecological building retrofit
  • International programs to promote RES & RUE 
  • Building construction and quality assurance tools
  • Innovative building and retrofit concepts
  • Best practice

Results

458 participants representing 10 nations attended the symposium. On 8th and 9th of October the expert-conference was participated by 321 experts, decision-makers and stakeholders.

It was the 3rd ökosan symposium, which was hosted by AEE INTEC, and is now one of the most important conferences on sustainable building renovation within the german-speaking nations.

It was possible to welcome participants from the nations mentioned below:

  • Belgium
  • Germany
  • Finland
  • Ireland
  • Italy
  • The Netherlands
  • Austria
  • Sweden
  • Switzerland
  • Spain

The support service during the conference was to take care of all participants and speakers. But in addition to that everybody was provided with the entire conference documents printed and as a CD-Rom. All presentations held by the speakers are also available.

Perspective

It is assumed that all the interesting presentations and discussions during these three days could increase know-how-transfer for market-implementation and initiate a broader application of new technologies.

The positive results from all participants (which can be read in the evaluation forms and were heard during the conference) motivate AEE INTEC to host in two years the next symposium - the conference "ökosan 11".
