1. Passive Houses A regional energy efficiency solution? Ir.-arch. Erwin Mlecnik, senior expert R&D

2. ‘Passive house’ can be a regional solution for energy efficiency and quality improvement in the built environment  What are the real needs/ problems?  What are the lessons from passive houses?  How can regional development be introduced?  Expected consequences? Content

6. SEE 2001

7.  Need for integrated approach  Improved quality - High energy efficiency – cost effective  Need for market assurance  Energy performance  Comfort  Levers for quality improvement Needs / problems

8.  Factor 4 – factor 10 – factor 20  Natural capitalism Rapid development of the ‘Passive house’ concept Basic & applied research

9.  ‘Passive house’ advantages:  Energy performance standard set (demand space heating < 15 kWh/m 2.a)  Knowledge available (www.europeanpassivehouses.org,..)  Comfort and financial issues examined (CEPHEUS,..)  Tools available for skill development (PHPP,..)  Quality assurance procedures available (certification,..) Basic & applied research

19. How to market? Quality increase reached! Energy efficiency = added benefit THERMAL COMFORT VISUAL COMFORT ACOUSTICAL COMFORT AIR QUALITY USER FRIENDLY LESS MAINTENANCE HEALTHY COST EFFICIENT BUILDINGS Basic & applied research

20. What to market?  Reduction of heat losses  Improved airtightness  Use of passive solar gains  Comfort ventilation  Efficient household equipment  Renewable energy INTEGRATED CONCEPT Regional development

21.  Clustered technology groups  Glazing  Frames, doors  Thermal insulation  Mechanical ventilation  Heat production  …  Technology does not cause CHANGE Regional development

23.  ‘Change agency’ to stimulate innovation  Regional = reduce geographical distance  SME oriented  Technology is a 2-way exchange of information Regional development

24.  Crucial = start  Pressure to approve innovation  Provide gatekeeping & communication channel  Credible change agent  Recommend innovations with beneficial consequences Regional development Arch.: denc!-studio, photo: PHP Arch.: E.
