2 Agenda 1. Project Aim and Project Structure 2. Approach 3. Analysis 4. Integrated Assessment 5. Exemplary Results (Case Study Leipzig)

3 Project Aim and Structure Assess Conditions of Brownfield Re-Vitalisation (exemplified through sites of German Railways Group) Comparing brownfield and greenfield developments a. Model Regions b. Location Types Analysis of land use patterns a. Spatial b. Economic c. Environmental Integrated Assessment Recommendations

4 Approach 2 Modell regions 5 Location types 8 Municipalities

5 Approach: Location Types Location Types a 3b 4 5 Prosperous large city (except city centre) Less prosperous large city Peripherally located small or medium-sized town In between (interspace) zones with starting conurbations In between zones of less densitiy or peripheral regions with starting conurbations Medium sized town outer central area Suburban area = greenfield

6 Approach: Analysis Inner city brownfield portfolio Spatial Analysis Selection of model sites Identification of re-use proposals Economic Analysis Environmental Analysis Integrated assessment

7 Spatial analysis Brownfield portfolio Macro analysis (Identification of development focuses/ regional level) Check formal and informal restrictions Interviews with local authorities On-site analysis (functional and urban context) Micro analysis (model site) Scoring model Re-Use Proposal

8 Economic Analysis Real Estate Feasibility Real Estate Market Actors and economic incentives : DB - Investor Municipality Brownfield Government aids and subsidies RES invest

9 Environmental Analysis Traffic implications in the environment (emissions and space) Ecological structure of the region Traffic volume Ecological Site Value Scenario 1 (current use): & Scenario 2 (reuse proposal) Environmental compartments (soil, water, climate/air) Landscape Scenery Biodiversity Soil Sealing Soil Quality Groundwater Regeneration 0 Biota (flora, fauna and man) Fresh Air (Ground-)Water Quality Air Convection Air Quality Current Use Reuse Proposal Environmental site value

10 Assessment: Economic Viability economic disadvantage economic advantage NCV - Investor > 500 Tsd > 100 Tsd > 10 Tsd 0 > 10 Tsd > 100 Tsd > 500 Tsd NCV - Municipality 0 > 500 Tsd > 100 Tsd > 10 Tsd > 10 Tsd > 100 Tsd > 500 Tsd economic disadvantage economic advantage

11 Assessment Eco-Efficiency = value of product or service environmental effect or resource consumption 4 Environmental site value (--) (-) (+/-) (+) (++) Value (Municipality)

12 Case Study Leipzig Former Railway Yard Leipzig-Plagwitz Location Type 1 Site (DB AG): ha Former railway yard: Few buildings Railway tracks Western part of Leipzig URBAN II area Vicinity housing areas and commercial zones

13 Leipzig brownfield re-use proposal: Miscellaneous land use Northern part: commercial buildings, research and development Southern part : detached houses

14 Leipzig (greenfield) Alternative greenfield development: Detached houses

15 Economic Analysis: Leipzig Stakeholder Scenario Brownfield Greenfield NCV before revitalisation / project development Project Owner / DB AG present Municipality present 0 0 NCV after revitalisation / project development Investor expected worst case Municipality expected worst case Time scale: 10 years

16 Environmental Site Value Leipzig Brownfield Comparison before and after development Soil structure 4 City and landscape quality 3 Soil quality 2 Biotope quality 1 0 Groundwater recharge Fresh air formation Groundwater quality Fresh air exchange Air quality and emissions Present use Re-use proposal

17 Environmental Site Value Leipzig Greenfield Comparison before and after development Soil structure 4 City and landscape quality 3 Soil quality 2 Biotope quality 1 0 Groundwater recharge Fresh air formation Groundwater quality Fresh air exchange Air quality and emissions Present use Re-use proposal

18 Eco-Efficency Brownfield Environmental Ökologische Standortwertigkeit Site value NCV Investor: EURO Plagwitz - Ist - present Plagwitz - Soll exp. Plagwitz --Soll exp (Worst (worst Case) case) NCV Investor: EURO 1 NCV Owner: EURO 0 (--) (-) (+/-) (+) (++) Value Nutzwert (Municipality) Kommune

19 Eco-Efficiency Greenfield Ökologische Standortwertigkeit Environmental Site value Greenfield Grüne Wiese - present - Ist Greenfield = - exp Greenfield Grüne Wiese - exp - Soll (worst (Worst case) NCV Owner: Case) EURO NCV Investor: EURO NCV Investor: EURO 0 (--) (-) (+/-) (+) (++) Nutzw ert Kommune Value (Municipality)
