6 WP 5: Case Studies

7 Case Study Stuttgart Stuttgart, Schlüsselwiesen Built Flats Rough analysis of the building example (saving potentials, investments, LCC) Discussion with the administration preparing a presentation to the owners. Goal: Start of a detailled study Quelle: Google Maps Planned start of the reconstruction 2014 Folie

9 Case Study Berlin Berlin - Hansaviertel, Bartningallee 16 Built in 1957, listed building Architect Hans Schwippert 60 Flats

10 Case Study Berlin 2-story flats Facade = energetic desaster, bur protected (listed building) Thin concrete walls Large glass surfaces Large unused roof area New heating system in the cellar District heating

11 Case Study Berlin Cogeneration in the future is possible Contracting i an interesting topic for the residents

12 Case Study Aachen Aachen- Burtscheid, Klosterweiher 2-14 Built in Flats

13 Case Study Aachen

14 Case Study Aachen Problems Non-insulated inner walls flat/staircase Large glass surface in the staircase area Non insulated basement ceiling Non insulated roof ceiling Large garden area owned Perspectives Cogeneration Insulation in the problematic building areas Solar energy usage thermal and electric District heating

15 Case Study Bonn Bonn - Bad Godesberg, Zanderstraße 2-14 Built in Flats

16 Case Study Bonn The facade The housekeeper Heating system The facade inside

17 Case Study Bonn Large glass surfaces in the facade area Old heating system Not any kind of insulation in the facade area Very thin walls behind the heating radiators Average age of the owners over 65 (former residents since it was built) Non insulated cellar ceiling over the underground garage Decision for the energetic refurbishment of the cellar area

19 INTEGRATED PLANNNG METHOD FOR THE SYNERGETIC POWER SUPPLY OF SETTLEMENT COMPLEXES M.Sc. RWTH Georgi Georgiev Fraunhofer

20 Contents Urban policy and regulations + technical solutions + economy + + society + stochastics Developing of a planning process for the sustainable energy supply of settlement complexes based on practical experience in indiustry complexes, industrial areas, settlements with a mixed usage (work, living, industry), as well as residential districts Investigation of intelligent common energy supply on a district level: Heating, electricity, combined methods and systems. Fraunhofer

21 Contents Urban policy and regulations + technical solutions + economy + + society + stochastics Fraunhofer

22 The three factors, used for the systemic assignment of the energy stakeholders on the analysis level in the respective settlement area, are: Type and quality: Is the respective object an energy consumer or a producer, which scale does it have? Amount: detailed empiric analysis of every relevant stakeholder Topology, as energy transport distances lead to losses in efficiency and additional costs Fraunhofer
