Carbon Reduction Demand
• EU 25, today: ca. 9.5 t/CO2 per capita• World, 2050 (-50%): ca. 1.2 t/CO2 per capita• This would mean a reduction in EU25 of 87%!

From European Worst Practice ….
ETAP Forum, Brussels, June 11, 2007
… to European Best Practice!
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, UW = 1.1; N: 2-glazing, UW = 1.4
• Groundfloor windows: U-value: 1.4• TOTAL Cost: 240 EUR/m² + VAT

Conclusion
GermanyAndreas Hermelink
• We have the obligation to master a triple challenge which is far beyond the usual marginal improvements.
• Let’s•satisfy occupants’ needs•within environmental limits•at reasonable cost!
• SOLANOVA proves: It is possible!
