The approach of urban renewal by premise of large-scale GHG reduction through a case study in Rotterdam

2. Global warming 2 °C global temperatures is the tipping point

4. technologies = solution

5. technologies = solution ?

6. The Netherlands Energy Efficient Action Plan (EEPA) 2007 Transport sector >21% energy saving Household sector >22% energy saving until 2016

8. Large-scale application limited time, space and € by urban management with urban integration

9. by design a favorable condition for adopting energy saving measures Large-scale application limited time, space and €

10. This project illustrates integrated strategies concerning sustainable energy by a urban renewal master plan

11. Energy use pattern vs. spatial values

12. Greenhouse gas (GHG) emissions in local level from transportation

13. Bicycle Amsterdam vs. Rotterdam = 29% vs. 19% Data proved energy use pattern on transport — municipalities level

15. Energy use on housing

16. Large restructure housing area in Rotterdam south until 2030 Pre-war housing area post-war housing area Urban renewal area Necessity of spatial restructuring to achieve the goal of greenhouse gas (GHG) reduction. The priority switches to the urban renewal master plan

20. Systematic for refurbishment Source: Dr. Georg Wagener-Lohse, CEBra - Centre for Energy Technology Brandenburg, Cottbus - feasible in cost and time — old housing refurbishment Schemes of development II -- old housing renovation Boiler, Tube insulation Ceiling insulation Thermostatic valves Insulation of one wall Insulation of all walls I A I B I C Standard full energetic refurbishment Standard full refurbishment * estimated effect on consumption in kWh/m² Saving* time ? >20y ? >10y 45% 5-10y 30% 5y

21. Schemes of development II -- old housing renovation Good market value and add-values are possible Learn from precedent Falmouth, UK, 2003 30% energy saving 5.5 yr pay-back Berlin, Ger, 2007 50% energy saving 7 yr pay-back Veenendaal, NL, 2002 28% energy saving 7 yr pay-back

23. Tip A subsidy scheme for existing housing: - solar water heaters, - heat pumps - solar panels - Properly adopting low or zero carbon energy technology

24. Strategies ; spatial related solution
