Solar Thermal in Major Renovations and Protected Urban Areas (URBANSOLPLUS)
Article 13 of the 2009/28/EC Directive requires minimum share of renewables for new buildings and major renovations. Given the current very low construction rate for new buildings, renovation play a key role for addressing a large part of the building stock, thus assuring a fruitful implementation of the Directive. However, building codes very often do not allow a wide use of renewables, because their scope just include only new buildings and not renovations and since building located in protected areas are often exempted, even though the extension of these areas is actually relevant. Moreover renovations, especially of large buildings, are complicated from several points of view.Supporting the implementation of Article 13 of the RES directive the goal of the project was to enhance the integration of Solar Thermal (ST) systems especially in "demanding situations" understood mainly as major renovations of multi-family buildings located in urban and/or protected areas.
To fulfill this goal, the IEE UrbanSolPlus project put together a consortium of experienced and newcomer partners with the intention of building a "know-how pool" in order to allow the participating local partners (replication partners) to implement and/or improve experiences and models. These participating (replication) local partners are Lisbon, Berlin, Barcelona, Province of Benevento and Province of Pescara.
1. Installation of a number of solar thermal systems on large residential buildings in the participating communities: Operative figures are available from Barcelona, Berlin and from Lisbon for the years 2011-2013 (figures have been calculated using some assumptions):
- Berlin, total 462 m2,
- Barcelona, total 7,234 m2,
- Lisbon, total 346 m2
2. Capacity building for Local Authorities, Energy Agencies and local stakeholders. For each of the replication communities the following has been produced:
- 5 development strategies for promoting the use of solar thermal in urban quarters, building renovation sector and protected areas
- 5 master plans for developing the use of solar thermal in one representative urban block, quarter or area
3. A total of 19 practical implementation of models for developing solar thermal in demanding urban areas have been developed.Increasing awareness and knowledge about the use of solar thermal plants in special situations and urban development. This project is now closed.
- Lack of knowledge about solar thermal: in Slovenia, Province of Pescara, Province of Benevento the knowledge of solar thermal systems is not that diffused as in other countries. The development of very well constructed tools and of comparative knowledge on solar heating potential for buildings, like the feasibility decision base developed in the project, has reached many stakeholders, who are now more aware of possibilities and importance of ST in urban areas.
- Involvement of dwellings owners: in all the process it is important to involve the key actors, in order to better explain the possible expectations and to look at the needs of the future plant owners. Working with condominiums is a complex decision process: to reach the success it is important that all the key stakeholders play their role in establishing a good and clear communication channel, developing suitable technical solutions and helping in funding processes.
- New solar energy strategies: the awareness about the potentials and their feasibility and the implementation of successful cooperation models can lead to new solar energy strategies at higher level through political commitments. In Portugal this was done with Lisboa Ciudade Solar.keholders play their role in establishing a good and clear communication channel, developing suitable technical solutions and helping in funding processes.
Project duration: June 2011 to May 2014.
