Project summary
The Bioclimatic boulevard of Vallecas is an open space for one of the major urban developments of Madrid (Ensanche de Vallecas). With the aim of creating a public space of similar quality as that provided by natural trees, 3 "urban trees" (called “Climatic”, “Ludic” and “Media” trees) have been installed that combine bioclimatic design principles, metallic structures, vegetation and Photovoltaic modules architecturally integrated. The trees are energy self-sufficient, which means that their annual electricity consumption is compensated by the PV electricity produced.

Best practice project
The project has been awarded as "Best practice energy project" by the Regional Government of Madrid (Directorate General for Economy and Technology Innovation).

Special PV project info
PV architecture and building integrationThe structures of the bioclimatic trees are made of steel tubular profiles, the PV modules are integrated in metallic structures (16 structures with 64 PV modules in each tree). Inverters are located at the basement of the PV modules structures, thus minimising DC cable losses.
PV ownership
Tariffs and meteringFeed-in-tariff
The economic benefits obtained from the PV production will be used for maintenance of the bioclimatic trees.
