POLIS - Identification and Mobilization of Solar Potentials via Local Strategies

POLIS was an european cooperation project that focused on implementing strategic town planning and local policy measures to utilize the solar energy capability of structures in European cities. Only a strategic approach by the municipality can enhance the expanding integration of small-scale, decentralized energy applications into the built environment.

The aim of the project was to identify and evaluate current practices in solar urban planning, and unite the key responsible 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.

To ensure the viability solar energy for new structures in the urban environment, certain requirements need to be included in development planning and building legislation. Several instruments are available to promote solar energy such as municipal agreements or private law commitments.

Existing buildings should also be guaranteed consideration for the installation of solar energy systems. A comprehensive knowledge of the style and structure of these buildings is essential to establish strategic planning to unlock their solar potential.

Through the cooperation of those cities that were engaged in solar urban planning, the mobilization of solar urban potential was promoted at a local level. Since municipalities are the key actors in the process of urban planning and local initiatives it was important that the planning departments of towns and cities be intrinsically involved in the POLIS project.

The first stage of this project involved the identification of the current situation in each of the countries represented in the consortium in terms of the initiatives in the area of ​identification and mobilization of the solar potential, urban planning practices and policies and incentives in place. In parallel, successful projects were analyzed for the appropriation of some of these successful initiatives on the part of the consortium cities. The result of this work was compiled in Urban Planning Solar Manual, available in all languages of the consortium, including Portuguese.

In the context of this project all partner cities, Lisbon, Paris, Lyon, Munich, Malmo and Victoria, have developed a Solar Plan Action. The Solar Plan Action for each city can be found on the project web site.

The Lisbon's Solar Action Plan was developed and approved by the Municipality in 2010, contemplating the development of several pilot projects:
- Evaluation of the potential solar installation of solar systems in the built heritage of Lisbon at
the parish. The Lisbon Solar Potential Map can be seen in the following link:

- Definition of the goals of adoption of solar, thermal and photovoltaic medium and short term. This action was not developed during the project.

- Analyze the potential for integration of solar technologies in the Urban Plan of the District of Boavista (currently the subject of a rehabilitation program in the context of  ECO-NEIGHBORHOOD).
- Identifying the solar potential of the built heritage of Lisbon City Council at the level of service buildings supplied with medium and low voltage special (in portuguese). Lisboa E-Nova in partnership with Lisbon Municipality and Wee Solutions developed this study

- Organization of a Solar Training in Urban Planning and a Cycle of Workshops on Solar Technology.

As a result of these actions and cooperation between the various European partners, the consortium aimed to identify measures that contribute to the definition of public policy at the level of development of municipal urban planning regulations, as well as new legal and financial mechanisms to encourage the adoption of these technologies in the urban environment.
