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%

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


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)

General model The Hammarby Sjöstad model

The EcoCycle Model of Hammarby sjöstad – The Hammarby Model


Solar Energy

PV Cells Solar panels

10% of electricity supply 50% of tap warm water


The key to Hammarby Sjöstads success –


- Integrated planning


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

10 000 apartments (25 000 residents) 30 000 workplaces

Period of implementation 2010 - 2025

Passive and Plus Energy Buildings


Sustainable transportation


Active homes and demand control

• Increased energy efficiency and peak levelling

Dispersed local energy production

• Integration of local energy production

Use of electric vehicles and smart charging

• 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.

1+1=>3

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.

Swedish experiences, summing up

Collaborative and communicative processes

Consensus at an early planning stage

Systems thinking

Transdisciplinary collaboration

Monitoring and evaluation

The City leads the way – is a forerunner

Planning is more than regulating (”PBA+”)


Avoid suboptimisation

– economic benefits Facilitate co-operation

– sharing of knowledge

children and grandchildren”

Thank you for your attention!

Sustainable cities – an issue of responsibility for our and future generations…
