ETAP Forum, Brussels, June 11, 2007 CO2-Emissions – Scenarios

ETAP Forum, Brussels, June 11, 2007 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%!

ETAP Forum, Brussels, June 11, 2007 Symbiosis Solar Energy (Building, Quarter, Town) Efficiency (buildings & dwellers, supply systems)

ETAP Forum, Brussels, June 11, 2007 SOLANOVA – Factor 10 Philosophy

ETAP Forum, Brussels, June 11, 2007 SOLANOVA - Much More Solar …

ETAP Forum, Brussels, June 11, 2007 SOLANOVA – … Much Less Fossile

ETAP Forum, Brussels, June 11, 2007 Measured Space Heat Consumption

ETAP Forum, Brussels, June 11, 2007 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, U W = 1.1; N: 2-glazing, U W = 1.4 Groundfloor windows: U-value: 1.4 TOTAL Cost: 240 EUR/m² + VAT

ETAP Forum, Brussels, June 11, 2007 Satisfaction with Temperature

ETAP Forum, Brussels, June 11, 2007 Energy Share in Low-Income Household

ETAP Forum, Brussels, June 11, 2007 Annual Energy Cost Savings

ETAP Forum, Brussels, June 11, 2007 Satisfaction with Space Heat Cost [%]

ETAP Forum, Brussels, June 11, 2007 Estimated Sales-price of Flats

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

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

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)

ETAP Forum, Brussels, June 11, 2007 Replication Potential for SOLANOVA 100 Mio people in Eastern Europe only!

ETAP Forum, Brussels, June 11, 2007 Conclusion Germany Andreas Hermelink 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!
