Training for Renovated Energy Efficient Social housing (TREES)

Download PDFDownload PDF
Currently, existing material focuses mainly on new buildings, despite the fact that existing buildings offer the biggest energy-saving potential. This project aimed to incorporate energy efficiency into further education for architects and social housing managers. Educational material includes techniques, tools and case studies, developed and reviewed by a group which includes teachers themselves. Workshops were held to gather feedback and to prepare for inserting the material into courses.


  • Educational material (slides and texts) developed in which specialists describe advanced technologies such as integrated solar hot water and preheated ventilation air.
  • Modules now available online including tools for assessing energy savings from techniques including thermal simulation and life-cycle assessment in terms of energy, cost and environmental impact.
  • Case studies available in six countries.
  • Energy consumption in social housing can be reduced by a factor of four, but continuing education for building professionals is needed due to lack of awareness. In addition, political will is needed because investment costs are high.

Lessons learned

  • Efficient techniques and methods exist to reduce by a factor 4 the energy consumption of social housing in Europe, they are implemented in a few renovation projects,
  • Most building professionals are not aware of these possibilities, continuing education is needed, and our project allows educational material to be prepared,
  • The investment cost for a large scale energy efficient renovation is high and would require a strong political will (but importing even more expensive fuels would certainly be worse for low income persons).
