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!

to European Best Practice!

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 21 glazing, shading, UW
  1.1 N 2-glazing, UW 1.4
• Groundfloor windows U-value 1.4
• TOTAL Cost 240 EUR/m² VAT

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
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)

Conclusion

• 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!
