future cities

what are future cities?

definition

Future Cities are cities and communities that use electronic, digital technologies, renewed agricultural and economic strategies to make city life sustainable in the long term and keep the impact of city life on the environment neutral.

Scarcity of resources

  • Economical use of resources
  • Lack of space (9.7 billion people by 2050)
  • Large quantities of building materials are needed
  • Selecting building materials sustainably
  • Build with foresight and efficiency
  • Saving materials (renovating houses)

Scarcity of resources

Water shortage

  • Climate change (heat/drought)
  • Local water shortage
  • Much water in one place (urban problem)
  • many Water pipelines
  • Salt water filtration plants
  • Economical use of water

Transport

  • Local public transport
  • Environmental impact is greatly reduced (transport sector accounts for 20% of global greenhouse gas emissions)
  • Pollution for humans is strongly reduced (smog)

---> Less traffic jams

--->Safety

Transport

Cycling

- Very environmentally friendly

- Healthy and happy people

Private mobility

Abolition

- Replacement (autonomous e-taxis)

Alternatives

energy

  • Increase in the amount of energy required worldwide
  • Efficient use of available energy (LEDs, automatic switching, public transport)
  • Short distances in the city
  • Germany (76% of all people live in cities and energy consumption is decreasing)

  • Energy supply
  • Electricity as the dominant energy source
  • Renewable energies
  • Electricity grids (reserves)

energy

Climate change

Urban climate

General increase of temperature

A lot of surfaces (high absorption)

- Few plants in cities

Green areas and green houses

CO2 in cities

- High CO2 emissions in cities (cars, industries)

- Few plants (low regeneration of air)

- Burden for humans and environment

Goal: - climate neutral cities

- Green cities

Green Copenhagen

- Many small parks (pocket parks)

- Greening of houses (law)

- No high-rise buildings

Energie

- Large offshore wind farm off the coast

- Climate neutral by 2025

- European environmental capital (2014)

Resource use

- Renovate instead of building new

- Building forms optimized (wind locks, green roofs)

- Technical progress (e-taxis, charging stations)

Green Copenhagen

Traffic

- Bicycling attractive

- Bicycle transport free of charge on the S-Bahn

- Bicycle fast routes

- Companies support the use

- Long network of wide bike lanes (400km/2.5m)

Public transport

- well developed

- One ticket for many means of transport and routes

- Bicycle and public transport are connected

- Metro runs day and night (3min 5-24h and 20 min 24-5h)

Pros

pros & cons

Clean streets, buildings, interiors

Money saved on gas tank fillings

Better air quality

More active, healthier people

Saving energy

through separate waste disposal, many public waste disposal points

through use of bicycles and public transportation

through more green spaces and car-free zones

through bike use

through LED, renewable heating systems, efficient construction methods

Cons

- Sustainable, modern renovation projects are expensive

- Green spaces need special care

- Clean city depends on people's initiative

Cons

Cities of the Future, are they worth living in?
