11. ETAP Forum, Brussels, June 11, 2007 From European Worst Practice ….

12. ETAP Forum, Brussels, June 11, 2007 … to European Best Practice!

13. ETAP Forum, Brussels, June 11, 2007 Measures for European Best Practice Decentral ventilation units with 82% real heat recovery, one ventilation unit per flat Ca. 75 m² solar thermal area as canopy Easy heating system solution with radiators 10 cm insulation of cellar ceiling Roof insulation: 30 cm with green roof Wall insulation: 16 cm polystyrene (additional) Flats windows: S and W: 2+1 glazing, shading, U W = 1.1; N: 2-glazing, U W = 1.4 Groundfloor windows: U-value: 1.4 TOTAL Cost: 240 EUR/m² + VAT

19. ETAP Forum, Brussels, June 11, 2007 Satisfaction with Flat

20. ETAP Forum, Brussels, June 11, 2007 Additional Thoughts and Benefits 1 Considering ONLY energy cost savings: Amortisation at current price: 17 years Amortisation at +60% price: 11 years ATTENTION: Thinking only in terms of this kind of amortisation does not solve the problems it created (e.g. energy scarcity; greenhouse effect)! Near future: Costs for CO2 certificates

21. ETAP Forum, Brussels, June 11, 2007 Additional Thoughts and Benefits 2 Very effective filtering of air (industrial area!) Noise protection due to high quality windows Very high thermal comfort (winter & summer) Steady, low indoor CO2 concentration No mould growth Increased well-being of people: Less costs for diseases Less absence from work place Higher productivity More useful space (wardrobe in front of external wall possible, less/smaller radiators)

26. ETAP Forum, Brussels, June 11, 2007 Conclusion Germany Andreas Hermelink hermelink@solanova.org We have the obligation to master a triple challenge which is far beyond the usual marginal improvements. Lets satisfy occupants needs within environmental limits at reasonable cost! SOLANOVA proves: It is possible!
