  1. ControlThe forgotten option in retrofitting Energy led retrofitting of dwellings 04 september2013 Wouter Borsboom*, Leo Bakker*, Ivo Opstelten (Platform31), Wim Kornaat*, Bas Knoll*, Piet Jacobs* *TNO

  2. Much achieved in the Netherlands How long does it take to retrofit?

  3. Day 1 Prefabricated facades back side

  4. Day 2 Prefabricated facades front side

  5. Day 3 Prefabricated roof

  6. Day 6/7 Finishing zinc en roof trims

  7. Day 8 Moving scaffolding

  8. Final result Zero energy in 8 days!

  9. How much money does an average consumer spend on energy in his dwelling in the Netherlands in 15 Years? 42.000 Euro

  10. Development in retrofitting Roosendaal 2010 130.000 Kerkrade 2011 100.000 Apeldoorn 2012 Integral renovation costs incl. VAT 80.000 60.000 Zero on the meter TimeE - performance

  11. Out of a selection of 21 projects in het Netherlands toward nearly zero energy how many houses use control? Ventilation: 3 controlled airflow inlet (passive) and 5 CO2 controlled ventilation systems Shading: None Heating/cooling: Most projects have central thermostat

  12. Why use control Reduce health impact Improve Comfort Save Energy

  13. In the indoor environment what has te greatest impact on health?

  14. Control Strategy • Particle filtration (PM2.5) • Example: Filtering of outside air • Combustion control (Acrolein) and moisture • Example: multigas sensor Low emitting materials Then dilution ventilation (odour)

  15. How much energy can we save with ventilation Flow control air inlets Efficient fans Improved airtightness Demand control Heat recovery Demand control and heat recovery

  16. Improved comfort by shading

  17. Energy saving by shading

  18. Saving potential by zone heating

  19. How do people use their windows Depending on outside temperature

  20. How can we save energy in heating and cooling Number of open windows Outside Temperature

  21. Development of a innovative control in the Herb Project • When a warm period / overheating is expected: • Additional ventilation to cool building mass • utilize solar shading to reduce solar gain

  22. InnoEnergy project proposal DCCS Ref 1 Ref 2 Holistic

  23. First measurements at first test site

  24. Challenge: reduce energy and increase user acceptance and well being
