Case Study Stuttgart

Stuttgart, Schlüsselwiesen 29-33

Built 1965

34 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

Planned start of the reconstruction 2014

Case Study Berlin

Berlin - Hansaviertel,

Bartningallee 16

Built in 1957, listed building

Architect Hans Schwippert

60 Flats

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

Case Study Berlin

Cogeneration in the future is possible Contracting i an interesting topic for the residents

Case Study Aachen

Aachen- Burtscheid,

Klosterweiher 2-14

Built in 1970

60 Flats

Case Study Aachen

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

Case Study Bonn

Bonn - Bad Godesberg,

Zanderstraße 2-14

Built in 1970

59 Flats

Case Study Bonn

The facade The housekeeper

Heating system The facade inside

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

Contents

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.

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
