  2. Energy as new vector in urban planning 1. Urban planning 2. How to analyse a city energetically? 3. How to unfold future opportunities? 4. Define “energy areas” for the further development 5. Challenges 6. Outlook and conclusion

  3. Urban planning Urban planning + is one of the oldest cultural techniques of mankind + is driven in parts by architects, in parts by rather pragmatic considerations to supply new business opportunities and cheap housing + environment a major issue (noise, emissions and so forth) but energy is only considered a minor item In times of climate change: a new urban planning is required including energy and the impact of climate change as major consideration!

  4. How to analyse a city energetically? Time

  5. How to analyse a city energetically?

  6. How to analyse a city energetically?

  7. How to analyse a city energetically? Space

  8. How to analyse a city energetically?

  9. How to analyse a city energetically? + add energy in the existing planning tools like GIS. + make early estimates of heat, cooling and electricity demand + embed the results for new quarters in the overall picture of the city + look then for city-optimal not for quarter-optimal solutions

  10. How to analyse a city energetically? + create a data-base on buildings, major services and industry, use modern methodologies like laser scanning to add as much information as possible + local authorities should supply in regular frequencies energy reports about the city as a whole + co-operation with the local suppliers to up-data the data-base and to include time resolved information + map available renewable resources, map waste heat reservoirs + supply special energy reports for new building areas

  11. How to unfold future opportunities? Models help to understand opportunities and technical limits New-Urbs TIMES-NT Monte-Carlo Simulation of new demands

  21. Challenges Development of new structures: + ageing societies + new definition of workplaces due to information and communication technologies, only a fraction of the time in the “office” + new forms of shopping: will we by at some time vegetables via the internet, will a completely new infrastructure come up for home delivery? + how will the service sector be organised in the future? How will banks, insurance companies, schools, hospitals operate?

  22. Challenges City as centre of festivals and other leisure activities

  23. Summary and outlook + cities can play a major role in reaching a sustainable energy future + urban planning has to be revised to include energy as a major pillar in the reasoning + analysing the energy situation, monitoring developments should be become a “daily” procedure in city administration (building data base, …) + energy models help to show future opportunities and challenges, the use of models should also become part of the planning procedures + many challenges like “new economy” of cities require completely new approaches + urban planning considering energy might become of the key technologies for the 21st century
