Swedish ExperiencesIntegrating sustainability, energy and environmental issues
in urban planning
Energy summit in DublinSession 3: Meeting practical challenges of developing renewable projects20151217
SwedenConsiderable environmental improvements since the Stockholm Environmental Summit 1972
Strong political leadership
Economic instruments – carbon dioxide taxes
energy tax relief on renewables etc
Triple helix collaboration
Integrated planning
Embedded carbon dioxide emissions in imported goods and material are not included
Sweden has already achievedits 2020 targets: 50% renewable energyAnd 10% renewables in the sector of transport
Bio fuels22%
Coal4%
Oil/Crude oil23%
Natural gas2%
Others2%
Nuclear33%
Heat1%
Hydro11%
Wind2%

Total energy input in the Swedish energy system, 2013
Target for wind energy 30TWh 2020 from 12TWh 2013
Ulf Ranhagen Dec 2015
Sweden has a low share of solar energy (0,06% electricity from solar cells
2014) but it increases rapidly.
Potential 2020: 4TWh solar electricity (3%) and 4TWH solar heat
Long term potential 2020: 35-40 TWh solar electricity and 100TWh solar heat
Ulf Ranhagen Dec 2015
Primary energy600 TWh
Use of energy377 TWh (63%) and losses ofenergy221 TWh (37%)
Use of energy in different sectors377 TWh
Residentialand service sector

Final energy use in the residential and service sector 1970-2010
Energy sources for district heating 1970-2011 TWh

Swedish ”energy hero” – district heating and district cooling
Successful examples of low-energy and passive buildings
New buildings without heating systems –Lindås 15kWh/sqm
Renovation of existing apartments –Brogården, Alingsås
Buildings from 216 kWh/sqm to
85 kWh/sqm (60 kWh/sqm possible)

The key to Hammarby Sjöstads success –

- Integrated planning
Ulf Ranhagen Dec 2015
The Royal Seaport in Stockholm – transportation, logistical center, smart grids, smart buildings, eco-cycle model etc
2. By 2020, the CO2 emissions are cut to 1,5 ton per person/year
1. By 2030, Stockholm Royal Seaport is a fossil fuel free city district
Three comprehensive objectives:
3. Stockholm Royal Seaport is adapted to climate change effects
• An integrated infrastructure for charging electric vehicles
Energy storage supporting customers and grid
• Improved grid quality and levelling out of power peaks
Smart and electrified port
• Reduction of CO2 emissions with high voltage connections for the ships
Smart grid stations
• Improved operational safety through increased automation
Centre for operations, research and follow-up
• Operation, research and development as well as follow up of the smart grid

Symbiosis means the mutual integration of organisms in a mutually
beneficial union. In this context symbiosis means finding synergies
between urban systems that save natural resouces and cost less.

The SymbioCity Approach promotes urban review and planning processes that consider potential value-adding synergies between urban systems

SWECO Symbio City Applications Globally
SWECO 16 Examples 2002 - 2012
Cork in February: View towards the South Docklands along the northern key of River Lee.
The mild climate – mean temperature pending between +5 - +20 degrees Celsius – makes
the concept of the so-called Passive Building most feasible.

Collaborative and communicative processes
Consensus at an early planning stage

The City leads the way – is a forerunner
Planning is more than regulating (”PBA+”)
Ulf Ranhagen Dec 2015
Avoid suboptimisation
– economic benefits Facilitate co-operation
– sharing of knowledge
