Presentation of POLIS


POLIS is a European cooperation project that focuses on implementing strategic town planning and local policy measures to use the solar energy capability of structures in European cities. Only a strategic approach by municipalities can enhance the expanding integration of small-scale, decentralised energy applications into the built environment.

The aim of the project is to identify and evaluate current practices in solar urban planning, and unite the key parties of this process to create a more cohesive planning and legislation practice for solar developments. The physical structure of a building and its position within the urban pattern is clearly integral to its solar energy capabilities. Availability and orientation of external surface area is a crucial factor in the design of active solar systems and also important for the reception of passive solar energy. More than any other renewable energy integrated solar energy relies on the qualification of the built environment.

Best practices in Europe

Manual for solar urban planning
By Lisboa E-Nova

The Solar Urban Planning Manual of European Best Practice Solutions intends to be a guide for politics and urban planners to design local strategies towards the identification and mobilisation of solar potentials in their cities. This guide presents experiences in four categories of expertise: Identification of solar potential, Mobilisation of solar potential, Solar urban planning and Policy and legislation.

In the chapter "Identification of solar potential" some of the best practices presented will focus on specific potential assessment projects like the Lanzarote Solar Potential Study, a study developed for the Spanish Lanzarote. The chapter "Mobilsation of solar potential" presents projects on the definition of incentives and subsidies to adopt solar technologies. "Solar urban planning best practices" focus on planning instruments specifically developed considering the integration of solar technologies in the built environment. Finally, the chapter "Policy and legislation" analyses political instruments like ordinances and development frameworks dedicated to the adoption of solar technologies.

Clear guidelines are presented towards the integration of sustainable practices in urban operations, namely regarding buildings location and orientation according to the needs of passive cooling and heating strategies and the promotion of thermal comfort through the optimisation of solar gains. Urban operations should also focus on energy efficiency strategies, namely for natural lighting, and renewable energy adoption, especially for electricity and hot water production.

POLIS Workshop in Europe

Hamburg workshop
workshopBy Climate Alliance

The first POLIS project workshop took place in Hamburg, Germany, in November 2009 during Climate Alliance’s annual Municipal Climate Protection Conference (Kommunale Klimaschutz-Konferenz).

The overall aim of the workshop was to set up a national competence group to discuss the subject of solar potential in cities and municipalities so as to compile various local solar projects and pass these on to multipliers, such as urban planners, municipal decision-makers, business developers and local suppliers.

Malmö workshop
By Climate Alliance

The Swedish POLIS partner invited interested parties to a “Solar Energy in Planning Work” workshop in Malmö town hall on March 3, 2010. Around 25 people took up the invitation, including staff from the city planning office, real estate office, environment department, department of internal services, roads and parks department as well as representatives from other cities.

The workshop began with presentations providing inspiration and background information on both solar energy in cities and the POLIS project. Lisa Ossman who represents a cooperation of 24 cities determined to increase the use of solar energy talked about Sweden’s first “plus-energy multi-family house with solar heat”, in which the surplus heat will be fed into the district heating network. The city-owned housing company, “Eksta”, introduced its new passive houses and provided information about a newly-constructed multi-family dwelling for which 36% of the total heat requirements are supplied by solar heat.

Polis’s Website is online!
The new internet website for the POLIS program is now online : www.polis-solar.eu It presents all the information concerning the program and the results of the work done in each country. You can now download the national assessments for solar urban planning in each participating country, and the local assessment of each city (Munich, Paris, Lyon, Lisboa, Vitoria-Gasteiz and Malmö). You can also find a description of several current practices for Solar Urban Planning in Europe.

Best practice guide for solar urban planning in Europe
Focusing on Local Deployment strategies for the mainstreaming of solar technologies, the POLIS partners have gathered a series of Best Practices developed in their countries that details experiences and projects in four areas: Identification of solar potential, Mobilization of solar potential, Solar urban planning and Policy and legislation. These experiences will soon be presented and available to all the interested municipalities that whish to orient their cities urban planning developments within a solar maximization approach in the Solar Urban Planning Manual of European Best Practice Solutions. Stay tuned…

focus on one city

snabBy city of Munich

The City of Munich is trying to support solar energy generation with several initiatives and on different levels.

First: solarthermal – an urban design project concerning seasonal heating

In the late 90s we started in our local Planning Department developing a project supplying solar energy to the heating system of housing areas. After several basic studies decision fell on a new area being developed – a former military barracks – called Ackermannbogen.

So the solarthermal project is called “Solare Nahwärme am Ackermannbogen” or shortly “SNAB”. The idea is collecting solar heat and supplying a 6000 cubic meter storage, so the heat can be used in those months were heat is needed. 50% of the demand should be supplied by solar heat. Final evaluation of the project, that was finished two years ago is still ongoing.
