Retrofitting Technology Solutions

• Session D

2
Speakers

• Daaf De Kok on recycling of concrete
• Jan Desmyter on eco-innovation barriers in the
  construction industry
• Andreas Hermelink on a pilot project of
  refurbishment of multi-dwelling building
• Agnès Thibault on the importance of the SME in
  the construction industry
• Ronald Rovers on the need to tackle the existing
  building stock.

Client Awareness

• The more demanding, experienced and
  professionalised the client, the more likely it
  will pull for renewal and innovation.
• Increasing the competence of clients as buyers
  and demand setters as well as partners in the
  design and construction process, reinforces their
  innovation driving facilities.

4
Need for Education and Training of SMEs and the
architects

• There is not a lack of techniques and
  innovations, there is a lack of technicians.
• Stimulate young people to enter the industry
• Innovative technologies, processes or products
  require education and training.
• Find an equilibrium between the generalist and
  the specialist.
• Clustering of SMEs and competences could be a
  solution.

5
Need for RTD and Demonstration

• Introducing a new technology in the construction
  industry needs intensive research and
  technological development.
• It has to be demonstrated/proven that the
  customer/client can be convinced of the utility
  and performance.

6
Need for Standards

• As Sordyl stated the hallmark of an accepted
  technology is its inclusion in standards such as
  building codes and specifications. It provides
  designers, specifying professionals and
  contractors with
• Confidence in the viability of the technology
• Basic information for its application
• It reduces the perception of risks associated
  with its use.

Complexity of the Job

• Insulation of roofs, cellars, facades,
• Ventilation
• Windows air and water tightness, insulation
  performance
• Installations lighting, heating, cooling,
  electricity
• Renewable energies
• Water use of rain and grey water, etc.

8
Role of the Government

• Stimulate RTD
• Stimulate demonstration
• Lead by example
• Adapt regulations, not to overregulate (a new
  barrier), but to give confidence in the
  technologies.
• Focus on behavioral changes.

Conclusion

• With the existing technologies a substantial
  improvement can be realised. For energy
  reductions of up to 90 were mentioned.
• Nevertheless there is still room for additional
  improvements.
